Pest Control in Castle Rock, Colorado
OMNIS Pest Control is a locally owned Castle Rock company that has treated homes and businesses in town since 2013. We handle mice, rats, ants, spiders, wasps, hornets and wildlife. Call 720-583-4126 or ask for a free quote, and we will call you back within one business day.
Locally Owned Since 2013
OMNIS Pest Control started in 2013 and has been based in Castle Rock ever since. Our office is at 2274 Manatt Ct, Unit A10, and our technicians work the same streets you drive. Bryce Wardell, our CEO, has worked in Colorado pest control since 2007.
Castle Rock is the Douglas County seat, about 6,200 feet up along I-25 between Denver and Colorado Springs. That setting shapes the pests we see. Cold winters push mice, rats and spiders indoors, dry summers bring ants and wasps, and homes that back onto open space see more wildlife.
Every visit follows the same steps. We find how the pest is getting in, treat the problem, seal the entry points where we can, and follow up. We use as little product as the job allows and follow Colorado Department of Agriculture guidelines.

How We Treat Your Home
We start by finding the cause. Pests come in through specific gaps and stay for specific reasons, such as food, water or warmth, so spraying without finding them only brings the problem back.
- Find it. We look for the entry points and what is drawing the pest in.
- Treat it. We choose the lowest amount of product that solves the problem, with pets and children in mind.
- Seal it. Where we can, we close the gaps so the pest does not return.
- Follow up. We check that it worked, and removal is guaranteed.
Common Pests in Castle Rock
These are the pests Castle Rock homeowners call us about most. Each one links to the service page for your area.
Ants
Ants are most active from spring through early fall, when they follow food and water into kitchens, bathrooms and around slabs and patios. Store-bought sprays often kill the ants you see and leave the colony alone, which is why they keep coming back. Our Castle Rock ant control service finds the trail and treats the source.


Mice
Mice are the most common fall call along the Front Range. When nights turn cold in October, they move into garages, crawl spaces and walls, and a gap about as wide as a pencil is enough. Our Castle Rock mouse control service treats the problem and seals the entry points. Read how to keep mice out of your house, or when to call an exterminator for mice if you have already seen one.
Wasps and Hornets
Wasps and hornets guard their nests and will swarm anyone who gets too close, so nests under eaves, in sheds and by the garage door are best left to a professional. See our Castle Rock wasp control, hornet control and yellow jacket control pages.


Rats
Rats are less common than mice, but they do more damage once they get in. They chew wiring, tear up insulation and often nest in attics when the weather turns cold. Our Castle Rock rat control service removes them and closes what let them in.

Castle Rock Pest Calendar
- Spring. Ants wake up, wasp queens start new nests, and spiders become active again.
- Summer. Wasps, hornets, yellow jackets, crickets and mosquitoes are at their peak.
- Fall. Mice, rats and spiders look for warmth indoors once nights get cold, usually starting in October.
- Winter. Rodents settle into attics, garages and crawl spaces, and indoor problems often go unnoticed until spring.
A recurring plan keeps you ahead of each season. See our Castle Rock residential pest control plans.
