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.

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.

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

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.

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.
