Princeton: Rodents to Know Before an Inspection
Roof Rat
Long-tailed and nimble, the roof rat has a slim body, a pointed snout and large ears, and its tail is longer than its body. It uses fences, trees and utility lines to get onto roofs. Look in the attic for droppings with pointed ends and listen for running above the ceiling after dark.
House Mouse
Mice are the smallest of the three: grey-brown, big-eared and light enough to run along a pipe. They leave pointed droppings about as big as a grain of rice in cabinets and along garage walls, and they chew small, neat holes in bags and boxes to get at food or nesting material.
Norway Rat
Norway rats are the heavyweights, with blunt snouts, small ears and tails shorter than their bodies. They dig and stay near the ground. Look for burrows along the foundation or under a shed, gnawed trash carts and droppings with blunt ends in the garage or around the outdoor trash area.
Rats in Princeton
The City of Princeton's Code Compliance page says vegetation over ten inches creates an unsightly appearance, attracts mosquitoes and makes a property more susceptible to burglary, and that overflowing trash attracts flies and other pests. The page names mosquitoes and flies, not rodents. For rats, the same habits still help: keep the grass short, keep trash inside carts with the lids closed, and clear clutter along fences and walls. The rat control guide explains trapping and sealing when rats get inside.
What to check
- Check that trash carts close fully and are not overfilled.
- Look under the shed and deck for burrows and runways.
- Clear stacked materials and boxes from along the fence.
Mice in Princeton
At 84.8% of units, detached houses make up most of Princeton's housing, and each one gives its owner a full exterior to check. Mice can get in at the garage, where a gap under the door or around a pipe lets them in, and then move into the kitchen or laundry room. Check those rooms for droppings, set snap traps along the walls where you find them, and keep food sealed. Once catches stop, seal the gap. The mouse control guide covers trapping and sealing in order.

What to check
- Look along the garage walls near the floor for droppings.
- Look for pipe gaps behind the washer and under the laundry tub.
- Move bagged seed and pet food into sealed bins.
Keeping Rodents Out in Princeton
Princeton's housing is recent: 77.3% of units were built in 2000 or later and 12.0% from 1980 to 1999. Even so, any house can have openings a mouse will use, such as a cable hole left wider than the wire, a weep hole with no cover or a vent hood that does not close. Exclusion means finding each of those and sealing it with metal mesh, sheet metal or sealant. The rodent exclusion guide explains what a complete sealing job covers and how it is checked afterwards.

What to check
- Walk the outside and look for gaps around every line entering the house.
- Check that the dryer and bathroom vent hoods close fully.
- If the walls are brick, look for weep holes that have no cover.
Where Rodents Get Into Princeton Homes
Open Weep Holes Near the Ground
On a brick house, weep holes let water drain from behind the brick, but an open one is wide enough for a mouse. Check the bottom course all the way around and fit covers made for weep holes.
Garage Side Door
A side or back door into the garage is easy to overlook. Check its sweep and frame for gaps and chewing, and keep it closed.
Vent Hoods and Flaps
Dryer and bathroom fan hoods should close when not in use. A stuck or broken flap, or a missing guard, leaves a duct that leads straight into the house.

The Princeton cards show 77.3% of units built in 2000 or later and 12.0% from 1980 to 1999, with 84.8% single-family detached and 6.3% in buildings of five or more units. Two age shares are not shown because their margins of error are too wide.

Station: McKinney Municipal Airport weather station
Princeton's month cards rest on the McKinney Municipal Airport weather station and its NOAA normals. Its record puts average lows at or under 40F in January, February and December, and places the highest average highs in July and August. As the nights cool, it helps to check the garage and attic for any openings. According to Texas A&M AgriLife Extension public health training, Norway rat reproduction peaks in spring and fall, so a Princeton homeowner can use those seasons as reminders to check for burrows.

What Drives Rodent Control Cost in Princeton
Garage Clutter
A crowded garage takes longer to inspect and trap, and stored boxes may need moving. Clearing the floor along the walls before a visit helps the work go faster.
How Many Gaps Are Found
The sealing part of a job grows with each cable hole, weep hole, vent gap and door gap on the list. Ask to see the list before any sealing begins.
Rats or Mice
Mice in a garage can be a smaller job than rats nesting in an attic, which may add ladder work, trapping up high and cleanup of insulation.

Common Questions About Princeton Rodent Control
It is better not to. Bags on the floor are easy for mice and rats to chew into. Put bags straight into a cart with a lid, keep the cart closed, and rinse it now and then so food smells do not build up. If you must keep trash in the garage, use a sealed bin.
Seed is food for mice and rats, so store it in a metal or heavy plastic container with a tight lid, off the floor and away from the walls. Close opened fertilizer bags and keep them in a bin as well. Check the shelves now and then for droppings or chewed corners.
You can, but use covers made for weep holes so the wall can still drain. Do not fill them with mortar, foam or caulk. Clean out debris first, press the covers in firmly, and check them once a year. If you already have mice in the walls, deal with them before sealing.
Look for small, rough-edged holes in food packaging, chewed corners on boxes, and paired tooth marks on wood, plastic or wiring. Fresh gnawing looks pale and clean, while old marks darken. Larger, coarser marks can point to rats. Note where you find them to help locate the entry point.
The rat section above covers what the city's page says about overflowing trash. For rodents, the aim is a lid that closes every time. Rinse and drain food containers, flatten boxes to save space, and hold extra bags in a sealed bin rather than beside the cart. If it overflows most weeks, ask your trash service about a larger cart.
