Let’s face it – there are a lot of critters in Colorado. Mice, rats, bats, birds, raccoons, termites, spiders and insects of every shape and size are all out there looking for a cozy place to call home.

When you’re purchasing a home, the last thing you want is to find some unwelcome guests shacking up with you and your family. Pests and insects can cause significant property damage and even pose health concerns. That’s why it’s never a bad idea to call in a specialist for a pest inspection before closing.

Where Do We Conduct the Pest Inspection?

At Scott Home Services, our pest inspection is a complete visual review of the structure and foundation of the home. We follow the guidelines created by the National Pest Management Association and the NPMA-33 inspection procedure.

Our inspectors access and examine all readily accessible areas where pests and wood destroying insects might be a concern. Essentially, our pest inspectors will follow the same path as a standard home inspection. However, their sole focus is, of course, pests. The areas we inspect include:

  • Exterior and Grounds
  • Roof
  • Crawlspace
  • Basement
  • Attic
  • Garage
  • Interior
  • Additional Structures (sheds, outbuildings etc.)

What Pests Do We Inspect for?

Wood Destroying Organisms (WDOs) – This is a category of insects that feeds on wood, which includes termites, carpenter ants, carpenter bees, and wood boring beetles. Being that most homes have certain wood components, these critters can pose a serious threat to structural integrity.

Due to the relatively dry climate of the Colorado Front Range, our inspectors don’t come across WDOs very often. But we do find them from time to time, and we make sure to always stay vigilant for signs of WDOs.

This means inspecting the property for any evidence of live or dead WDOs. Our inspectors will also take note of any damaged wood, tunneling, termite mud tubes, or frass (tiny fecal pellets that several WDOs commonly leave behind).

Unfortunately, much of WDO damage may be hard to identify, as it occurs behind walls. So when we do detect any signs of WDO activity, we will recommend further evaluation from a specialist.

Rodents –  Rodents, especially mice and rats, are very common home intruders in Colorado. They like to shack up in less busy parts of the house, such as basements, crawlspaces and attics.

Our inspectors will always inspect the nooks and crannies of the premise looking for signs of rodents. The most prominent clue is droppings, but we will also often find signs of nesting or rodent trails in insulation.

Whenever we discover a significant presence of mice or rats, we always recommend consulting with a pest control company. Although they might look cute, these rodents can cause costly damage and unsanitary conditions.

Birds –  These critters are primarily nesting in certain parts of the roof and gutter systems or under decks. But we have also found them in less common locations such as chimneys or attics. Birds can also cause damage and make unwanted messes.

Wasps – It is very common to see wasp nests a the exterior of homes, especially under overhangs and soffits. This is generally a maintenance item, and we will recommend removal from a pro, as needed.

We also occasionally see wasp nests located inside the home, usually the attic. This can be more concerning, being that it is in the living space, and removal is recommended.

Other Insects – No matter how airtight your home is, bugs will somehow find a way inside. We see a lot of spiders, flies, ants, etc. While these types of pests aren’t usually much of a concern, our inspectors will make note for removal or extermination as needed.

Additional Animals – Having been conducting inspections for almost 20 years, our inspectors have seen quite the spectrum of animals in homes. Raccoons, bats, snakes, squirrels to name a few.

If our inspectors don’t actually see the pest, they can generally identify them by their droppings, and will recommend further evaluation when necessary.

How To Prevent Pest Intrusion

At Scott Home Services, we are all about setting our clients up for success. That’s why, during our pest inspections, we don’t only identify existing pest issues. We also make note of the ways that you can prevent future pest intrusion!

For instance, any holes, cracks or openings will be noted. This includes gaps in weather stripping, garage door gaps, holes or damage in screens, openings at penetration points, gaps at the eaves and all other vulnerable areas.

Many insects thrive in damp conditions (including subterranean termites), so we call out any moisture concerns around perimeter. In addition, our inspectors will mention any grading issues or improperly installed gutters that could promote moisture build up.

We all know that WDOs love wood, and any wood piles in contact with the home will be called out for relocation. Subterranean termites also love when they have access to wood sources directly from the soil – so we call out any siding or deck components that are in contact with soil.

Also make sure to trim back those bushes and trees! They may look pretty, but foliage in contact with the home or overhanging the roof (as shown below) give pests an easy route to access the home.

What Extra Add-On Services Should You Consider? https://scotthomeinspection.com/what-extra-add-on-services-should-you-consider/ Sun, 03 Nov 2024 19:47:27 +0000 https://scotthomeinspection.com/?p=18527 We offer many add-on services that can be performed alongside your home inspection. We consider ourselves a one-stop inspection shop! But which add-on services should you consider? We break it down for you here.

The post What Extra Add-On Services Should You Consider? appeared first on Scott Home Inspection.

]]>

A very common question we get when talking to buyers who are scheduling a general home inspection is “What other services do you think I need?” The answer can depend on the age of the home, whether any remodeling has been done, and what specific concerns the buyer has with the home. The more information we have about the home, whether it has been vacant for a long time, or whether it was meticulously maintained by the homeowner, the better we can help suggest whether certain add-on services are recommended.

There are a couple of services we usually recommend with every inspection, especially to those who might be moving in from out of state and may not be familiar with our area. We’ll go through each service in this article, and help you decide what extra inspections you should realistically consider.

Radon Testing During A Home Inspection

Radon Testing in Colorado is important because it is known for its elevated levels of radon gas, due to the specific mineral content in the soils. Radon exposure is the second leading cause of lung cancer after smoking, but you can’t tell if a home has high radon levels unless you test for it.

If a home does test high for radon levels, then that is something that your agent can help negotiate, possibly for a credit or for a radon mitigation system.

During the test, the radon monitor is always set in the lowest living area of the home, even if it is an unfinished basement. These areas may be converted into bedrooms, office space, or a play area for the kids, so it is important to test at this location. It is in the lower parts of the home where the concentrations are highest.

Whether a home has a basement, crawlspace, or is on a slab, it should still be tested for radon, according to the EPA. If a home has a radon mitigation system, it’s always good to check when the last test was performed.

We will check to make sure the system appears to be in working condition during the home inspection, but the only way to know that the radon gas is truly mitigated is to perform a radon test.

When Should I Get A Sewer Scope Test?

A Sewer Scope is another important service that is suggested, particularly for single-family homes and townhomes, where the owner is responsible for the condition of the line from the home to the city’s or HOA’s main sewer line.

While we believe this is one of the most important add-on inspections for all properties due to the high cost of repair, it is even more important for older homes.

Many older homes will have original sewer lines made from clay or cast iron piping. Older pipes are more prone to issues like root intrusion, cracking, and offsets than newer PVC lines. We highly recommend a sewer scope on these types of lines.

Sewer Scope Performed On Roof

What about septic systems? Many people tell us that they don’t need a sewer scope because the property is on a septic system. However, the main sewer line from the home to the septic tank is still susceptible to the same issues as a line from a home to a public sewer pipe and it should be checked.

Agents and buyers need to ensure that the septic tank itself and the rest of the septic system are properly inspected by a qualified septic servicer as well.

Problems with a sewer line can be very costly to repair, so it is always a good idea to have an independent and unbiased scope of the line. What is out of sight should not be out of mind!

Water Conscious Or Buying A Home With A Recent Water Event?

For properties that have had a “water event” or for clients with sensitivities to mold allergies, the Infrared (I/R) Scan service is a great way to help the inspector find hidden moisture concerns. An infrared camera reads the surface temperatures and moisture will show itself as cooler compared to the surrounding areas.

The camera cannot “see” behind the walls as some might think, but it can help the inspector focus on an area of concern, and recommend repair and mitigation of an area if active moisture is found.

Mold Air Sample Testing can further help to quantify whether there are elevated levels of mold spores in the home. A typical test consists of taking a minimum of 3 air samples. One is taken outside as a control sample, and then two more are taking on the inside of the home.

Using Infra-Red Cameras To Find Hidden Moisture Issues

The samples are then sent to a specialized laboratory, where the samples are analyzed for fungal types and levels. The results are sent back to the buyer the next business day, in an easy-to-understand report.

While these tests can be beneficial during any home inspection, we recommend them to buyers with allergies or mold sensitivity, or in homes where water issues may have been disclosed.

Hate Pests? We do Too!

For those who are particularly concerned about wood-destroying insects, rodent intrusion, and other critters in the home, a Pest Inspection might be a good option to consider.

The pest inspection is performed by a specialist who follows the National Pest Management Association guidelines. This inspection includes a visual review of the entire home including the structure and foundation where any evidence of pests will be documented.

Observations and recommendations will be made as to how they might be entering the home, and how best to address any future entry or intrusion.

If a home is older, if pest issues have been disclosed, if the home is built in a high humidity area, or if the home is a mountain home in Colorado, we will typically recommend this inspection.

Concerned About Energy Consumption?

If you’re an energy efficiency geek, or just want to save on your future energy bills, an Energy Check will help to identify several ways to improve your future home’s comfort and efficiency.

During an Energy Check, insulation levels will be checked in the attic, which is one of the greatest sources of heat loss in a home, in addition to the crawlspace or basement.

An I/R camera is also used to help find voids of insulation in the walls and ceilings. The HVAC system, and other components of the mechanical systems are also assessed for their energy efficiencies, in addition to the windows.

Appliances and lighting fixtures are reviewed as well, with recommendations made for possible improvements.

An Energy Check provides information to a future home owner, and is primarily information only for future reference. Many of these items may not be negotiable in the purchase of a home.

So should you order an Energy-Check with your inspection? Many newer homes have been built to higher energy-efficiency standards per the building codes of a particular area. However, some of the older homes that are inspected were built when energy-efficiency was not fully appreciated for either the homeowners or the planet!

Generally, you will receive the most benefit from this in older homes pre-1990s or if you are looking to make improvements.

What About My Drinking Water?

Finally, a Water Quality Test is a test that is becoming more popular as well. Everyone wants to know that the water they are drinking does not contain dangerous substances, but also that it doesn’t put unseemly spots on your dishes.

Even though the public source of the water is tested regularly, there may be older pipes through which the water runs that may contaminate it, resulting in poor quality water at the tap.

We utilize state-of-the-art equipment approved by the EPA, which provides immediate results. The primary components that are tested include lead, copper, chlorine levels, hardness, pH, alkalinity, and total dissolved solids (TDS).

Performing a water quality test

The age of the home and age of the neighborhood can help you decide if this test is right for you. Older homes, typically built before 1950 may have been built with some lead supply pipes that have yet to be removed. While we try to find these during the inspection, there may be small sections that are not visible.

Even if the house is brand new, it may be built in an older neighborhood. This increases the likelihood that there are lead supply pipes running to the lot itself. Any house built in an older neighborhood is a good candidate for this test.

When In Doubt, Give Us A Call.

Hopefully this article helps you decide which add-on services you should consider. When making a large purchase, like a new home, the more information you have the better.

If you are still unsure about which services to order with your home inspection, visit us online or contact us and our customer service team can help look up the home and give you recommendations.

We hope to hear from you soon on your next Colorado home inspection.

We’re not the only ones who enjoy Colorado’s warm and dry climate in the summer. Colorado has its share of bugs. Mosquitoes, bed bugs, Miller moths, and others that itch a ride on people, may be the most annoying, but others are even more destructive. It’s a huge problem when these pests decide to camp out around your house, yard and garden.

When inspecting your Denver home for problems like termites and mold, knowing which pests to look out for is crucial. Cockroaches, ants, and mosquitoes keep the exterminators busy, but beetles, girdlers, webworms, and billbugs are some of the most common backyard pests in Denver.

Scarab Beetles

Scarab beetles are another name for June bugs. They fly near bright outdoor lights and in direct sunshine. June bugs start as fat white larvae, eating foliage, flowers and killing the grass. Dead patches of grass or damaged plants may mean there are ground-dwelling June bug larvae on the lawn. Natural insecticides such as neem oil and Bacillus Thuringiensis (Bt) are effective ways to control them. Bt is a type of bacteria that acts as a toxin against insects like caterpillars and beetles, but it won’t affect beneficial bugs in the yard and garden.

Cranberry Girdler

Cranberry girdlers look like something out of the movie “Alien.” They’re light-gray grubs with orange-brown heads.  These sod-loving webworms eat turf roots before ascending on trees. Girdlers chew on Kentucky bluegrass, bentgrass, and fine fescues that grow in Denver yards. Chemical pesticides such as trichlorfon (Dylox), clothianidin (Arena), or halofenozide (Mach 2) are effective treatments to control these invaders. But keep in mind, trichlorfon is toxic to people, birds, and fish, and is easily absorbed through the skin. Clothianidin isn’t toxic to humans, but it can pose a risk to honey bees and other beneficial insects.




Billbugs and White Grubs

White grubs and billbugs feed on the roots of turfgrasses and can attract skunks and other mammals that dig into the sod searching for food. White grubs eat the roots of your grass and usually live on the top few inches of soil.

The best way to control infestations of white grubs is to attack when eggs are beginning to hatch. Parasitic nematodes are useful for controlling billbug and white grubs. Keeping your lawn watered will also help keep these insects at bay.

Source

Billbugs burrow down to grass stems and roots while they destroy turf crowns, especially in periods of drought in Denver. Billbugs are rather difficult to control because their hard bodies do not easily absorb pesticides. Kentucky bluegrass lawns are particularly susceptible to the larvae, and can spread from yard to yard.

Water and fertilizer may help to control infestations of billbugs and white grubs, especially before the grass enters dormancy in late summer. But if tunneling larvae kill grass plants before new blades have established roots, the young sod will die. Turf killed by billbugs must be reseeded.

Sod Webworms

These are moth-like insects that spin sleek webs in the grass and on foliage.  One of the most common backyard pests in Denver, webworms are gray or brown, and have dark spots on their backs.

Sod webworm larvae are about ¼ to an inch long and even though they’re living in the grass, they won’t do much damage to a healthy lawn. Organic fertilizers and lots of water will help keep infestations under control.

Other Common Backyard Pests in Denver

Source

They’re not a major problem, but some Denver lawns may see minor damage from chinch bugs. Various kinds of mites — spider, clover, banks grass — are critters to watch for.  Mites settle in during hot and dry months, even in the winter, feeding on grass roots and blades. Leafhoppers are very common in Denver as well. The tiny insects are ecru to light-brown and they suck the sap from grass blades.

Water, Water, Water!

There are various types of organic and chemical pesticides to control common backyard pests in Denver. But one of the best ways to keep the bugs away is to water your lawn. Lawn mites hate water! Water also washes previously-applied insecticides into the soil and grass roots, as it pushes grubs to feed closer to the surface of the turf.  Dry turf encourages bugs to dig down deeper to find water — that’s where the serious damage occurs. If it’s not raining, water the lawn in the early morning so that it won’t dry up before reaching the roots.

Source

Birds love to feast on worms, grubs, and other various insects. You can draw these feathered friends to the backyard with feeders and water baths. Make sure to put an agitator in the birdbath to avoid attracting mosquitoes! Before beckoning the birds, make sure there are no chemical insecticides on the lawn that will harm them.

Something that we come across very often during a home inspection are wasps or hornet nests. These nests usually come as quite the surprise when you are crawling in the attic or when you pull off an electrical panel cover! These are some of wasps’ favorite places to colonize as you can see in the pictures above. Wasps like to build their nests in areas that are protected from rainfall so these locations make perfect homes.

For the most part, wasps and hornets do not cause significant damage to your home, but they have obvious concerns for service professionals and home inspectors! A home inspection is not a pest inspection, but we can identify visible concerns with pests. At that point you should get a specialist pest inspection company to evaluate the problem and see if it needs to be addressed.

Prevention is the best way to treat a wasp or pest problem. Here is what researchers at MSU had to say:

Exclusion is the best defense against wasps and bees. If they can’t get inside the equipment, they can’t nest there. Many companies do a good job of making insect-proof housing for their equipment. But housing gets damaged; covers get left open, and not all equipment is insect proof to begin with. When wasps build nests inside electrical or telecommunications equipment you can’t just spray them with any available wasp spray. It might cause a short or cause damage or corrosion of components. – Blake Layton, Extension Entomology Specialist

Wasps can be more of a nuisance to humans than posing a real problem. They also serve a purpose in feeding on the population of other insects. Due to a global decline in wasp population it is best to avoid destroying their nests when it makes sense. Instead, proper sealing and wasp-proofing common nest areas can help prevent future issues in your home, yet helps to keep this pest-eating species thriving.

During a home inspection, our inspectors can attempt to identify any nests that are visible, and we can help to identify any open areas or penetrations that can be covered and sealed to prevent pest entry. However, if you believe pests are an issue in your home or the next home you are buying, contact us to schedule a pest inspection.

Wood Rot or potential termite damage can be present in older homes:

An interesting defect was found in an older 1940’s home this week by our Inspection Manager Luke. Down in the crawlspace of the home, a deteriorated piece of wood was spotted. Sometimes it can be difficult to tell the difference between wood rot and termite damage. Here is what Luke had to say about it.

“I thought it was wood rot from moisture damage, but if you got up close you could see the little tunnels typical of termites. Also, there was no moisture damage or dry rot anywhere else around this joist. This appears to be old termite damage, with the wood soft to the point that you could crush the whole joist with your bare hands in one area.  There were little tunnels and a mud like substance inside the wood, which appears to be consistent with termite tunneling. This is a very rare item to observe in our area.” – Luke Griess

As a result of this finding, we recommended to the buyer to have a pest inspection company come in to investigate for active termites.  We also recommended a structural engineer evaluate the beams to determine what repair or replacement of structural components is needed.  While this type of wood rot defect is very rare in our home inspections, it is exactly the reason you want a home inspection company that is willing to get into those hard to reach areas and do a full visual inspection for potential concerns.

At Scott Home Inspection, we perform all our Colorado home inspections to the American Society of Home Inspectors (ASHI) Standard of Practice.  All of the inspectors on our team are ASHI Trained and we visually inspect structural components and beams for this exact type of concern.

Our home inspection services in the the Denver, Boulder, Fort Collins and Colorado Front Range area, can help determine if there are wood destroying organisms in your home or future home. Learn more about our pest inspections here.
