Rodents
Deer mice & house mice
Deer mice live in the prairie grass and piñon around Penrose homes. Hay, sweet feed and bird seed pull them into barns in late summer, and cold nights move them into garages, campers and walls.

Pest control in Penrose, CO: quick facts
Quick answer
Pest control in Penrose, CO usually costs $100–$150 for a one-time general visit, or about $40–$60 a month on a quarterly plan. Penrose is in Fremont County, so we serve it on scheduled route days rather than same-day. Most acreage visits take about an hour and cover the house, barn and sheds for mice, black widows, wasps, flies and field ants.

Penrose is an unincorporated community in eastern Fremont County, on Highway 115 near where it meets US-50, roughly 30 miles west of Pueblo between Pueblo West and Florence. It isn't a town of tight subdivisions. Most homes sit on a few acres or more, with horse pens, hay sheds, small orchards, gardens, chicken coops and a lot of open prairie, piñon and juniper between neighbors.
That open country is the main reason Penrose pest problems look different from the river towns farther west. Deer mice come in straight off the prairie, prairie dog colonies sit on nearby pasture and vacant ground, horses and their manure bring flies, and every stack of fence posts or unused stock trailer becomes black widow habitat. The house is usually fine on its own; it's what surrounds the house that keeps feeding pests toward it.
A & M Pest & Termite Control works out of Pueblo, and we want to be clear about timing: Penrose is outside Pueblo County, so it's served on our scheduled Fremont County route days. We'll give you a firm appointment window when you book, and the drive doesn't change the price.
Which pests cause the most trouble on Penrose acreage?
These are the calls we get most from Penrose properties, with the local reason each pest turns up:
Spiders
Black widows in sheds & trailers
Dry Fremont County weather and plenty of stored gear suit the western black widow. Tack rooms, stock trailers, irrigation boxes and post piles are where Penrose owners meet them.
Spider control
Stinging insects
Paper wasps & yellowjackets
Barn eaves, loafing sheds, hay feeders and the underside of horse trailers are favorite paper wasp nest sites. Yellowjackets build in the ground and work orchard fruit in late summer.
Wasp removal
Ants
Field ants
Field ants build mounds in the sandy, gravelly ground along driveways, arenas and fence lines. They rarely nest indoors, but colonies next to the foundation send foragers inside.
Ant control
Fleas
Fleas from wildlife & prairie dogs
Dogs that roam pasture, rabbits and rodents under outbuildings, and nearby prairie dog colonies all keep fleas in the picture. Prairie dog fleas can carry plague, so they deserve real caution.
Flea control
Overwintering
Boxelder bugs on sunny walls
Shade trees planted around Penrose homes support boxelder bugs. In fall they bunch up on south and west siding and squeeze in around windows to spend the winter.
Preventive plansFlies on horse properties
Horse properties produce flies; there's no way around that. House flies and stable flies breed in wet manure, soiled bedding and spilled feed, and they're ready to bite or come indoors within about a week in warm weather. Cleaning stalls and spreading or composting manure on a regular schedule cuts numbers far more than spraying. Once sanitation is in place, we treat fly resting surfaces around the house, doors and porch.
Is it safe to clean up mouse droppings in a Penrose barn or shed?
It can be, if you do it the right way. Deer mice are the main carrier of hantavirus in Colorado, and they are common in the dry grassland and piñon-juniper country around Penrose. The virus spreads when dried droppings, urine or nesting material get stirred into the air, which is exactly what happens when someone sweeps out a tack room or opens a camper that sat all winter.
CDC-style wet clean-up
- Open doors and windows and let the building air out for at least 30 minutes
- Wear rubber or plastic gloves; add a well-fitted respirator for heavy contamination
- Spray droppings and nests with disinfectant or a bleach solution and let them soak
- Wipe up with paper towels and bag everything; never sweep or vacuum dry droppings
- Disinfect the area again, then wash gloved hands before removing gloves
Clean-up only helps if the mice stop coming back. On Penrose properties we trap and use locked bait stations placed where horses, dogs and chickens can't reach them, seal gaps in the house, garage and tack room with metal and hardware cloth, and give you a short list of feed-storage changes. See the CDC hantavirus guidance for the full clean-up steps, and our rodent control service for how we handle exclusion.
Prairie dogs and plague: what Penrose owners should know
Black-tailed prairie dogs live on open ground across this part of the Arkansas Valley, and their fleas can carry the bacteria that cause plague. Outbreaks can wipe out a colony quickly. Plague in people is rare and treatable, but pets that hunt in colonies can bring infected fleas home.
- Keep dogs and cats out of prairie dog towns and on a vet-approved flea preventive year-round
- Don't handle sick or dead prairie dogs, rabbits or rodents; report die-offs to your county health department
- Wear repellent on legs and boots when walking or working near burrows
- Keep woodpiles and junk away from the house so wildlife and their fleas don't settle near it
- Call a doctor promptly if fever and swollen glands follow a flea bite or contact with wildlife
We treat fleas in and around the home and outbuildings, and we can advise on reducing rodent harborage near the house. Prairie dogs themselves are wildlife with their own regulations, so colony management is a separate matter from household flea control. Our flea and tick page covers how indoor and yard treatments work together.
What makes Penrose different from other Fremont County towns?
A few local conditions shape the way we service Penrose:
- Space between buildings. A typical property has a house plus a barn, hay storage, a shop and maybe a coop or RV. Each one is its own pest source, so we inspect all of them on the first visit.
- Dry, open ground. Prairie, sandy soil and piñon-juniper favor deer mice, field ants and black widows over the moisture-loving pests found closer to the river.
- Animals on site. Horses, goats, chickens and working dogs mean bait placement and product choice have to be planned around them.
- Fruit and gardens. Small orchards and big gardens feed yellowjackets and mice through late summer.
- Distance. Some properties are a long way from the next house. We bring what we need to finish in one trip.
Because of all that, a quarterly plan that covers outbuildings tends to save Penrose owners money compared with calling every time a new pest shows up.
Penrose pest calendar
| Season | What Penrose owners see | What we focus on |
|---|---|---|
| Spring (Mar–May) | Field ant mounds open, wasp queens start nests in barns, mice still in sheds and campers | Ant treatment, outbuilding inspection, early nest removal |
| Early summer (Jun–Jul) | Fly numbers climb around pens, black widows active in stored gear, fleas on dogs | Fly-resting-surface treatment, web clean-out, flea treatment |
| Late summer (Aug–Sep) | Yellowjackets on orchard fruit, boxelder bugs gather, deer mice move toward hay | Ground-nest treatment, exterior sealing, bait stations |
| Fall (Oct–Nov) | Mice enter garages, tack rooms and walls; boxelder bugs slip indoors | Rodent exclusion, door sweeps, station checks |
| Winter (Dec–Feb) | Mice in campers, attics and feed rooms | Trapping, safe clean-up guidance, entry-point repair |
Penrose sits a little over 5,000 feet, and wind across open ground makes cold snaps feel sharp. The first hard freeze is when rodent calls jump, so late summer is the best time to book exclusion work.

Homes on acreage
A residential visit covers the living space, garage and foundation, then works outward to the barn, sheds and coop. We look for rodent runways, wasp nests, widow webs and ant mounds, and we explain what we find while we're there.
Horse boarding, small farms and home businesses
Boarding barns, hay sellers and small farm operations get scheduled rodent and insect service with written visit records. We keep products away from feed, water and animals, and plan bait placement around how your property actually runs.
Small habits that help on Penrose properties
- Store sweet feed, pellets and bird seed in metal bins with tight lids
- Stack hay on pallets with an inspection gap along the wall
- Clean stalls and pens on a regular schedule in warm months
- Park campers and trailers away from the house and check them before trips
- Wear gloves when moving posts, tarps and stored equipment
- Keep a gravel strip around the foundation instead of tall grass

Frequently asked questions
How much does pest control cost in Penrose, CO?
A one-time general visit in Penrose typically costs $100–$150, and quarterly plans run about $40–$60 per month. Large barns or heavy rodent problems are quoted after a free inspection. New customers get 10% off their first service.
Can you come to Penrose the same day?
Usually not. Penrose is in Fremont County, outside our Pueblo County same-day area, so we serve it on scheduled route days. Our line is open 24/7, and we'll give you the next available route day when you call.
Is there a travel charge for Penrose?
No. Penrose is part of our regular service area, and grouping visits on route days lets us keep the same pricing we charge in Pueblo.
Will you treat my barn, tack room and hay shed?
Yes. On most Penrose properties those buildings are where mice, wasps and black widows build up first, so we include them in the inspection and quote them with the house.
Is rodent bait safe around horses, chickens and dogs?
We use locked, tamper-resistant stations placed where animals can't reach them, and traps in sensitive areas like feed rooms and coops. Tell us about every animal on the property so we can plan placement.
How worried should I be about prairie dog fleas?
Prairie dog fleas can carry plague, so keep pets out of colonies, use flea preventives, and don't touch sick or dead wildlife. Human cases are rare and treatable, but see a doctor quickly if fever follows a flea bite.
Can you get rid of flies around my horses?
We can reduce them, but sanitation does most of the work. Regular stall cleaning and manure management come first; we then treat fly resting areas around the house, porch and doors.
Do mice really carry hantavirus in Penrose?
Deer mice are the hantavirus carrier in Colorado, and they're common around Penrose. Ventilate, wet down droppings with disinfectant and never sweep them dry when cleaning sheds, barns or campers.
