Rodent control in Denton, TX works best as a two-part job: trap the rats or mice already inside, then seal the openings they used so new ones can’t follow. Pest Renewal connects Denton homeowners with a licensed technician who inspects the attic, garage, and exterior, finds the entry points, and builds a plan around what’s actually living in your house.
In North Texas, rodent problems tend to surface as nights cool in fall. Roof rats climb in from trees and rooflines, Norway rats work in from ground level, and house mice slip through cracks most people never notice. Pest Renewal takes rodent calls in Denton, Midland, and Waco.

Signs of Rats or Mice in Your Home
Rodents are cautious and mostly nocturnal, so you’ll usually find their traces before you see one.
Droppings along walls
Dark pellets under sinks, behind the stove, or along attic joists. Mouse droppings are tiny and pointed; Norway rat droppings are larger with blunt ends.
Scratching in the attic
Scurrying or gnawing overhead after dark, especially in fall and winter, points to rodents nesting in insulation or running the rafters.
Gnawed wiring and boxes
Fresh chew marks on wood, plastic, or cardboard. Chewed wiring in an attic or wall is a potential fire hazard.
Greasy rub marks
Dark smudges along baseboards, beams, or the edge of an opening come from oily fur brushing the same route every night.
Shredded nesting material
Torn paper, fabric, or insulation bundled behind the water heater or in a storage box signals an active nest.
Burrows by the foundation
Holes along the slab, under sheds, or beneath woodpiles are typical of Norway rats, which dig at ground level and forage outward.
How Rodent Control Works
Traps handle the rodents inside today; exclusion handles the ones that would arrive next month. A complete service does both.
Describe what you’re noticing
Tell the specialist what you’re hearing or finding and where, and mention any kids or pets so traps go where they’re safe.
Inspection inside and out
The technician looks for droppings, runways, and rub marks, then walks the exterior and roofline for gaps at soffits, vents, garage doors, and utility lines.
Trapping along travel routes
Snap traps set along walls, rafters, and runways remove rodents quickly, with follow-up visits to check and reset them.
Sealing entry points
Gaps are closed with materials rodents can’t chew back through, such as metal mesh, sheet metal, hardware cloth, and sealant.
Final check
Once captures stop, traps come out and the technician points out any remaining weak spots.
What Affects the Cost of Rodent Control?
A rodent job can be a few traps in the garage or sealing an entire roofline, so one advertised price wouldn’t tell you much. The specialist will cover what applies to your home on the call, and our Texas pest control cost guide explains why rodent work is priced separately.
Number of entry points
A home with a handful of gaps costs less to seal than one with openings at every soffit, vent, and roof junction.
Roof height and attic access
Two-story rooflines, steep pitches, and cramped attics take more time and equipment.
Rats versus mice
Each species calls for different traps and sealing materials, and roof rats often mean more work up high.
Follow-up visits needed
Trapping usually takes several return trips until activity stops.
Attic cleanup
Removing droppings, nesting debris, or damaged insulation is a separate scope from trapping and sealing.
Roof Rats, Norway Rats, or House Mice — Which Do You Have?
Roof rats are slender climbers with tails longer than their bodies, and they nest high in attics, walls, and trees. Norway rats are heavier and burrow at ground level around foundations, sheds, and woodpiles. House mice are small enough to squeeze through very narrow cracks and nest in walls, cabinets, and stored items.
That difference shapes the plan. Roof rat work focuses on the roofline and overhanging limbs, while Norway rat work targets burrows and ground-level gaps. Mice demand the most meticulous sealing: Texas A&M AgriLife notes a mouse can enter through a dime-sized hole or a ¼-inch gap under a door, while a rat needs a quarter-sized hole or ½-inch gap.
Why Does Sealing Entry Points Matter More Than Trapping?
Trapping removes the rodents living in your house now, but it does nothing about the gap they came through. As long as that opening exists, new rats or mice will find it, often by following the scent trails left by the last ones. Exclusion closes those routes, which is what stops a rodent problem from returning every fall.
- Gaps where an upper roofline meets a lower roof, chimney, or dormer
- Soffit and roof vents with torn or missing screens
- Garage door corners and worn bottom seals
- Openings around AC lines, plumbing, and cable entries
- Foundation vents on older pier-and-beam houses
Skip the loose poison
Rodents that eat rodenticide tossed into an attic may die inside walls where nobody can reach them, leaving a lingering odor. Any professional bait belongs in locked, tamper-resistant stations.
Is It Safe to Clean Up Rodent Droppings Yourself?
Small cleanups are manageable with care. Don’t sweep or vacuum dry droppings, because that stirs dust carrying viruses such as hantavirus into the air. CDC guidance is to air out the space, wear rubber gloves, soak droppings and nesting material with a disinfectant or bleach solution, then wipe up with paper towels. Heavily soiled attics are better left to professionals.
Between visits, store pet food and birdseed in sealed containers (a habit that also supports cockroach control), pick up fallen pecans, and trim limbs back from the roofline. Fall is a smart time to pair exclusion with a quarterly pest control plan, and soft attic wood is worth a termite inspection. See our Denton pest control page for local conditions.

Rodent Control FAQs
How long does it take to get rid of rats in the attic?
Plan on several follow-up visits rather than a single trip. Timing depends on how many rodents are present and how quickly every entry point gets sealed. If you still hear movement after traps stop catching anything, call back so the technician can look for a missed opening.
Why do mice show up in winter but not in summer?
Rats and mice don’t hibernate. When fall nights turn cool, they hunt for warm, sheltered spots near food, and a heated house with an unsealed gap is ideal. North Texas winters are mild, but cold snaps still drive rodents indoors, which is why early fall is the best time to seal entry points.
Are rodent traps and baits safe around kids and pets?
Traps belong where children and pets can’t reach them, such as in attics, behind appliances, or inside covered stations, and rodenticide labels call for tamper-resistant bait stations wherever kids or pets could get to the bait. Mention kids and pets when you call. Professional products are EPA-registered and must be used according to their labels.
Do you provide rodent control in Midland and Waco?
Yes. Pest Renewal handles rat and mouse calls in Midland and Waco through the same phone number as Denton. The approach is the same everywhere: find entry points, trap, and seal. Call, and the specialist will schedule a licensed technician who serves your area.
