4 Most Common Household Pests

To help you learn about these pests, here is a list of the most common pests in Denver.

The 4 Most Common Pests in Denver


One of the most common pests in Denver is ants. Ants are tiny insects that build complex colonies wherever they go. While these colonies are fascinating and intricate, they can also be a huge problem in your home.

When ants start to build a colony, they may start off small, but that changes extremely quickly. The queen ants are capable of laying hundreds of eggs at a time and because they can live for years, they can lay hundreds of thousands of eggs in their lifetimes.

If that is happening inside of your home, it doesn’t take long for the colony to be massive.

There are things you can do to prevent and minimize an ant infestation in your home. Much of this involves preventive measures like sealing food in airtight containers, blocking cracks and gaps in your home that could be letting the ants in, and setting traps around your home to catch the ants that are present.

These measures can be effective for small groups of ants in your home and prevent them from building up their colony in your home. However, these measures will likely not be enough to get rid of a large population of ants.

If you have a large population of ants in your home you should still make sure to do these things and maintain as clean of a house as possible. But to fully get rid of the problem you will need to call Denver pest control to treat your home.

Professional treatments will be much more effective at removing a large infestation than DIY measures will be.

Bed Bugs

Bed bugs are an unpleasant and growing problem in the United States. They take up residence in or around your bed and then feed on your blood during the night.

If you wake up and find itchy red bumps on your skin then it is possible that you have bed bugs in your home.

However, you will need to look for other evidence as well, such as shed exoskeletons or small blood stains on your sheets, to confirm the presence of bed bugs.

Bedbugs are, unfortunately, difficult to get rid of on your own. You may be tempted to purchase a pesticide to try and get rid of the bed bugs, but bed bugs have become resistant to common pesticides.

Instead, you’ll need to call Denver Pest Control to treat your home for bed bugs. These professionals will do treatments specifically targeting bed bugs and will be much more effective at removing them.

Of course, your best defense is prevention. Bed bugs are wingless creatures, so they can only come into your home by hitchhiking in.

Check everything that you bring into your home as soon as it arrives, from furniture to clothing and so on. This should help you catch any bed bugs trying to come inside before they can become a problem.


Cockroaches are a gross pest any time they show up. And unfortunately, when they show up they can also cause some serious problems in your home. They can leave brown smears on the walls, cause breathing problems for you or your family members, and more.

Because cockroaches can be harmful to your family, you should do all you can to prevent them.

The best way to prevent cockroaches is by getting rid of anything that could be attracting them to your home.

Cockroaches are particularly attracted to moisture, so keep an eye out for standing water, leaky plumbing, and even mold in your home. Eliminating these things can make a big difference in whether or not cockroaches show up in your home.

You can, of course, call Denver pest control for help preventing the cockroaches and to get rid of them if they do infest your home.


Spiders are pests that most people aren’t particularly thrilled to see in their homes.

However, because spiders can be beneficial in keeping other pest populations down, finding an occasional spider in your home is not a bad thing. What you don’t want to see is a lot of spiders in your home.

When a lot of spiders are showing up in your home, it’s a good sign that you might have other pests infesting your home as well.

The best thing to do in that situation is called Denver pest control so they can check your home, not only for spiders but for other infestations, and treat for them.

That being said, there are a few things you can do on your own to minimize the spider population in your house. One of those things is to keep a very clean house.

Spiders aren’t necessarily attracted to the mess itself, the mess does make it easier for them to hide. A messy home can also attract other pests which will attract more spiders.

If you do see a spider in your home, first try to determine what kind of spider it is. Most spiders aren’t terribly concerning, but there are a couple of spiders in the United States that are dangerous to humans, so it’s important to keep an eye out for them.

Once you determine that a spider is not dangerous, you can then vacuum it up or catch and release it outside of your house. If it is dangerous, you will need to be extremely careful around it so you don’t aggravate it. The spider should leave you alone if you don’t threaten it.

You can try spraying it yourself or calling Denver pest control for help. You should also have pest control check for more venomous spiders in your home.
