How to Seal Your Home for Winter and Keep Rodents Out

As the temperatures drop, different types of rodents like mice and rats start looking for a warm, cozy place to spend the winter and that often means inside your home. Attics, crawl spaces, garages, and even kitchen pantries become prime real estate for these uninvited guests.

Once inside, they don’t just settle in, they chew through insulation, wires, and stored items, contaminate surfaces, and can spread bacteria and allergens that threaten your family’s health.

The good news? You can stop them before they make themselves at home.

What’s Included in Our Winter Rodent Exclusion Inspection

At LONESTAR Pest Solutions, we offer a Rodent & Wildlife Exclusion and Monitoring Service a proactive, preventive approach designed to seal out pests before they find a way in.

Here’s what our Rodent & Wildlife Exclusion inspection includes:

A full interior and external inspection for signs of rodent activity.
Detailed exterior check of gaps, cracks, vents, and utility penetrations.
Installation of discreet monitoring or bait stations where needed.
Professional exclusion (sealing and proofing) of entry points to keep rodents and wildlife out for good.

This service isn’t just reactive it’s part of a comprehensive prevention strategy that protects your home year-round.

Early Rodent Prevention for San Antonio Homeowners

Here in San Antonio, our mild winters mean rodents don’t go fully dormant. Instead, they stay active and with cooler nights, they start sneaking indoors sooner than most homeowners realize. Neighborhoods with mature trees, older construction, and nearby greenbelts or drainage areas are especially vulnerable.

By the time you see a mouse or hear scratching in the attic, there’s a good chance a nest has already been built. That’s why early pest prevention is key. A single proactive visit now can save you hundreds (or even thousands) in future repair and cleanup costs.

Lonestar does our quarterly pest control and we had to call for re-spray of our kitchen due to these 100 plus degree temperature days. They sent Eddie over right away and he was so helpful telling me to pick up dog food every day, plug drains daily, use vinegar solution for drains, and make sure they always spray an area of the custom cabinets that has a gap between the cabinets and wall. He was the best! Really educated me and was so patient and even funny as I stared wide eyed over his knowledge of all things cockroaches.

Have used Lonestar for years for normal treatments inside and outside, but just recently used them for mosquito control prior to an outdoor graduation pool party. EXCELLENT RESULTS AND PHENOMENAL SERVICE! We had them do a general area fogging and then leave-behind portable remote controlled area “mister” — we haven’t seen a mosquito in two weeks!

— John Seamon

We have used Richard’s team for years. Recently we learned our neighbor’s had termites. We contacted Lone Star to learn about our options. The solution provided was better than solutions our neighbors suggested. In fact, we learned of several pitfalls that our neighbors might encounter (beyond higher cost over the long term).
