Anyone in Round Rock dealing with mice or rats, or hoping to keep them out.
What to look for
Seeing one in daylight usually means there are more. A mouse fits through a gap the size of a dime. You hear them at night and find droppings by morning. Rodents are mostly unseen.
- 1Small dark droppings on top of the water heater.
- 2A musky or ammonia-like smell in closed rooms.
- 3Live sighting, especially during the day.
- 4Scratching or scurrying sounds in walls or ceilings at night.
- 5Chewed holes in the bottom of cabinets or drawers.
- 6Tracks or tail drag marks in dust or flour.
Why it’s worth acting soon
- Mice breed fast, every few weeks.
- Droppings and urine contaminate food and insulation.
- Gnawed wiring can be a fire risk.
- Nests and odor get harder to clean the longer they stay.

Under the sink is the first place to check: the hole where the pipe passes through the cabinet back is often cut much bigger than the pipe.Which rodents live around Round Rock.
They burrow along foundations and enter low. Roof rats are common around Round Rock too. They climb, and come in high through attic vents and branches. House mice are the most common rodent in Round Rock homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
When they move in.
Listen for them in the attic after dark. Spring is breeding season. Small problems grow fast. Check for gaps before then. Roof rats are active all year.
This is what a proper seal looks like: metal mesh fastened with screws and sealed at the edges. Foam or caulk on its own gets chewed through.How they get into houses here.
Daylight under a door means a gap. Homes from Round Rock out to Austin share the same weak spots, so the checklist below works across the area. For roof rats, check soffit vents, gable vents and eaves. Trim branches back from the roof. Many homes in Round Rock sit on slabs. Garage seals, brick weep holes and pipe gaps are typical entries.

Rats avoid them for days. - Rub marks: rats leave greasy smudges along walls and beams. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized.
Sealing small gaps yourself.
- Hardware cloth: use quarter-inch mesh over vents and larger holes. - Door sweeps: close the gap under garage and exterior doors. - Expanding foam: fine on top of mesh, useless on its own. - Check your work: daylight through a gap means it isn’t sealed. - Steel wool or copper mesh: pack it into small gaps first. - Sealant or mortar: cover the mesh so it stays put.

Mice and rats nest in engine bays and chew wiring. Park in a closed garage when you can. Check the air filter box for nesting. Clear birdseed and pet food from the garage.

What affects the price
- Whether insulation must be removed and replaced.
- Materials used for sealing: mesh, sheet metal, mortar.
- Crawlspace or slab; crawlspaces add labor.

What's your biggest concern about rodents?
When to call for help
Attic cleanup is hard to do safely without training. They take a longer, more careful approach. Call right away if you see rats. So is a dead-rodent smell. Droppings in several rooms are another sign. Call if you hear them in the attic or walls.
What you can do yourself
Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off. Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins.

Local research
Rodents in Round Rock, TX: what the public record shows
Before you compare quotes, it helps to know which rodents actually live in Texas, when they are busiest around Round Rock, and what the state figures look like. Everything below links to the agency or university page it came from.
Flea-borne (murine) typhus cases reported in Texas, 2008-2025
Texas reports more flea-borne typhus than any other state; rats and their fleas are the natural reservoir.
Texas Department of State Health ServicesRodent species recorded in Texas
- House mouse (Mus musculus) — Enters at 1/4 inch; 5-10 litters per year; eats about 200 small meals a night.
- Norway rat (Rattus norvegicus) — Burrowing rat of basements, sewers and ground floors; tail shorter than head plus body.
- Roof rat (Rattus rattus) — Climber of attics and trees in warm and coastal regions; tail longer than head plus body.
- Deer mouse (Peromyscus maniculatus) — Primary U.S. hantavirus carrier; lives throughout Washington and the interior West.
Rat control in Texas is a flea-borne typhus issue as much as a structural one, so flea treatment goes with rodent removal.
For context, nationally
- 1/4 inch (the width of a pencil) — Smallest gap a mouse can enter. CDC
- 890; 35% fatal; 94% west of the Mississippi — Hantavirus cases reported since 1993 (through 2023). CDC

Questions people ask
How do I choose a rodent control company?
Ask what happens if rodents come back. A good company talks about sealing, not just traps. Make sure they're licensed in Texas. Ask how they seal gaps and what materials they use.
Do I need to replace attic insulation?
Light activity can often be cleaned up. Ask the inspector to show you before you agree to replacement. Only if it's heavily soiled or flattened by nesting.
Is it safe to clean up droppings myself?
Wait five minutes, then wipe up with paper towels. Never sweep or vacuum them dry. For small amounts, yes, with care. Wear gloves and spray the droppings with a bleach solution.
Will rodent control harm my pets?
Bait stations are locked. Tell the company about your pets before they start. It shouldn't. Traps go where pets can't reach.
Can I just seal the holes myself?
Foam alone won't stop them. Rooflines and vents are harder, and that's where a pro helps. Small gaps, yes. Use steel wool or copper mesh, then seal over it.
