A Guide To Common Pests In Denver, CO

Colorado is known for its beautiful landscapes and natural wilderness. For many, the opportunities presented by nature are the reason they live in the state. Even if you're in Denver, you're not far from the mountains and the plains and all the critters that live there. This close proximity to nature is all the more reason to know about the pests that cause problems in the area. These problems include property damage, health concerns, and contamination. Knowing what pests can infest your property will give you the upper hand against them.

Since 1986, Absolute Pest Control has been an innovator in the Colorado pest control industry. We are built on the foundation of employee contentment and customer satisfaction. With knowledgeable staff, no contracts, and climate-based pest control, you won’t find another pest control service as honest and trustworthy as Absolute Pest Control.

When it comes to ants, it's never just one or a handful of insects; it’s hundreds and even thousands of individuals. This is because ants are subterranean social insects, meaning they mostly live underground in large colonies. The most popular species in the area are carpenter ants, sugar ants, and pavement ants. Although each of these species looks and behaves differently, they will continually infest in large numbers.

Species like carpenter ants are more destructive than others because they tunnel through wood, weakening it and damaging the structure of a property. Species like pavement and sugar ants are more of a nuisance than dangerous, but even if these species don’t cause damage or transmit diseases, they can contaminate food, making people sick.

For most ant species, you can try the following tips to prevent them from coming into your home:

  • Remove entry points: Cracks in the foundation and walls, doors, and windows should have proper screens and weather stripping.
  • Remove food sources: Store food in airtight containers, clean up crumbs and spills, and don’t leave pet food lying around; replace water-damaged wood.
  • Remove water sources: Fix leaking pipes and don’t let water stand on your property.

Although store-bought products might seem like they can get rid of an ant infestation or prevent them, they are often ineffective and used incorrectly. Not to mention, store-bought products can quickly run up an expensive bill. Instead, call in the professionals at Absolute Pest Control to get the job done right the first time. We will inspect your property, treat existing problems, and help you prevent them from coming back. To learn more about our ant control services, contact us today.


German cockroaches are the most popular invading cockroach species. Cockroaches have a reputation for being one of the dirtiest pests in the world. If they get inside your home, they will contaminate food and cooking surfaces with bacteria which can cause dysentery and food poisoning. Kitchens are an ideal place for cockroaches because, like most pests, they enter homes for food, water, and warmth. 

Cockroaches are difficult to get rid of, and no matter the size and severity of the infestation, you probably won’t be able to get rid of every individual on your own. This is because they are great at hiding, have strong defenses, and reproduce quickly. To prevent cockroaches from infesting your home, try the following prevention tips:

  • Keep human and pet food in airtight containers.
  • Secure trash cans, both inside and outside.
  • Sweep regularly.
  • Clean countertops and pick up crumbs daily.
  • Repair possible entry points into the home.

The good news is, you don’t have to combat cockroaches on your own in Colorado. Absolute Pest Control has been trusted to take care of pest problems since 1986. Our experience and knowledge allow us to provide pest-free homes to our customers where they can feel safe. To get started with cockroach control treatments, contact Absolute Pest Control.

Miller Moths

Miller moths come from army cutworms found in crop fields in Kansas and Colorado, making them the most popular moths in the state. When cutworms become miller moths, they will migrate from the crop fields to the mountains, and during this time, they can find their way into homes. Unlike other moth species, miller moths don’t eat fabric. Instead, they leave a dusty substance on anything they touch.

Like other moth species, miller moths are attracted to light, but this can be used as an advantage when they are migrating. People can leave their outside lights off to keep moths from gathering near their homes. Although miller moths are not dangerous, they are annoying, and no one wants to deal with them inside their home. To keep them from getting into your home, try:

  • Keeping lights off at night.
  • Switching white light bulbs out for yellow bulbs.
  • Sealing cracks and possible entry points.

Because miller moths are specific to Colorado, a local pest control company is your best bet when protecting against them, Absolute Pest Control has been serving the area for decades, and we're knowledgeable about the specific needs of Colorado residents.

Rodents like mice, rats, pocket gophers, and voles are common home- and property-invading pests in Colorado. They cause many problems, such as property damage, health concerns, and crop damage. Rodents can transmit diseases such as salmonellosis, hantavirus, leptospirosis, tularemia, and more. They can also carry parasites like fleas and ticks, making them dangerous to pets and people.

In addition to health problems, rodents can cause significant physical damage to homes and gardens. Rodents' teeth never stop growing, and to keep them from getting too long, rodents constantly chew. If they get into a home, they will chew through wires, pipes, structural wood, insulation, and more. On the other hand, voles are notorious for eating vegetables right out of people’s gardens. 

Rodents will try to get into homes for shelter, food, and water, and most of them only need a small space to squeeze through. To try to prevent rodents from getting into your home, you can do the following to discourage them:

  • Repair holes, cracks, and damage to the foundation and roof.
  • Make sure doors and windows close properly and don’t have holes around them.
  • Keep food appropriately stored in the home.
  • Clean up crumbs.
  • Take the garbage out frequently and make sure outdoor garbage cans close properly.
  • Fix leaking pipes and water-damaged wood.

Rodent infestations can be overwhelming. It’s not like dealing with tiny insects; the removal of rodents is much more complex. Instead of trying to handle them alone, you should get help from the professionals. Absolute Pest Control can handle any rodent in your Colorado home and make sure they won’t return.

Spiders are an essential part of a healthy ecosystem; without them, pests like mosquitos would be out of control. However, their helpfulness does not discount how scary they can be if they are in your home. A common species in Colorado is the wolf spider. This species isn’t venomous to people, but they still have a painful bite that can cause irritation.

There are only two venomous species in the United States. One of these species is the black widow, known for its shiny body and red hourglass marking. The other venomous spider is the brown recluse, but they are very rare in Colorado. No matter what kind of spider it is, no species is welcome in any home. 

To keep spiders from getting into your home or from living on your property, do the following:

  • Seal cracks in walls to keep them from getting inside.
  • Remove clutter from your home and yard to eliminate harborage areas.
  • Dust regularly to remove webs, so spiders aren’t able to catch food.
  • Don’t leave food lying around, as this can attract other insects that spiders eat.

No one wants any kind of spider in their home, especially dangerous ones. But unfortunately, they will find their way in. At Absolute Pest Control, we are dedicated to keeping our customers safe through prevention, treatment, and education. It is just as important for us to get rid of pests out of your home as it is for us to give you the tools and knowledge you need to protect yourself. If you need spider control or want to learn more about prevention, contact us at Absolute Pest Control.

Stinging Insects

Some stinging insects are often confused for their non-aggressive counterparts, bees. Wasps, yellowjackets, and hornets are more aggressive than bees, but can vary depending on species. Social stinging insects — meaning they create one large nest for the whole colony — are territorial. If they feel threatened, they will attack in numbers, and some, like yellowjackets, can bite and sting multiple times.

When it comes to being stung by one of these insects, it will cause swelling and redness, but it can be worse for people that are allergic to the venom. Anaphylaxis can occur, which can be life-threatening. Unfortunately, many people might not know if they are allergic to stinging insects until they get stung, which is why it is important to try and deter them from making nests on your property. You can do this in the following ways:

  • Limit sweet things outside like flowering plants, fallen and rotten fruit, hummingbird feeders, and open soda cans.
  • Make sure to rinse cans before recycling them.
  • Clean out garbage cans frequently.
  • Keep compost piles away from your home.
  • Discourage nest building by trimming foliage.

Another important part of preventing stinging insects on your Colorado property is regularly checking for nests. However, when you do this, you should be careful and never touch a nest even if you think it is not active. You don’t have to deal with stinging insects alone; Absolute Pest Control is here to help. We are trained to handle these dangerous pests, so you don’t have to. To hear more about stinging insects, how to prevent them, and what to do if they nest on your property, contact Absolute Pest Control.
