Rodents are more than just a nuisance — they can cause serious damage to your home, spread harmful diseases, and contaminate food supplies. In San Antonio, the warm climate provides the perfect breeding ground for mice and rats, making year-round prevention essential. As a trusted local expert, Pro Defense Pest Control helps homeowners stay ahead of infestations with proven strategies that work.
If you want to keep rodents out of your home for good, here are some effective rodent control tips every homeowner should know.

1. Seal Entry Points Around Your Home
Rodents can squeeze through openings as small as a quarter-inch, so even the tiniest gaps can become a welcome mat. Inspect your home’s foundation, walls, roofline, and around utility pipes for cracks or holes.
Quick Fix: Use steel wool, caulk, or metal mesh to seal gaps. Avoid using materials like wood or plastic that rodents can chew through.
2. Eliminate Food Sources
A steady food supply is one of the main reasons rodents stay in your home. Keeping your kitchen clean and food properly stored can make your home far less inviting.
- Store dry goods in airtight containers.
- Clean crumbs and spills immediately.
- Avoid leaving pet food out overnight.
At Pro Defense Pest Control, we often see infestations start in kitchens or pantries where food is left accessible.
3. Maintain a Clutter-Free Home
Rodents love clutter because it provides them with nesting materials and hiding spots. Piles of cardboard, paper, or fabric are perfect for them to build nests.
- Keep storage areas organized.
- Avoid stacking boxes directly against walls.
- Regularly declutter basements, garages, and attics.
4. Control Moisture Levels
Rats and mice need water to survive, and damp areas are ideal for them. Fix leaky pipes, keep gutters clean, and use dehumidifiers in damp basements or crawl spaces.
By eliminating water sources, you make your home less appealing to pests.
5. Use Traps Strategically
If you suspect rodent activity, traps can help reduce the population before it gets out of control.
- Place snap traps along walls and behind appliances.
- Use peanut butter or seeds as bait.
- Wear gloves when handling traps to avoid transferring human scent.
However, traps are only a short-term solution. For complete eradication, professional rodent control is often necessary.
6. Trim Outdoor Vegetation
Overgrown trees, bushes, and shrubs near your home can give rodents an easy path inside. Keep vegetation trimmed at least a foot away from your exterior walls, and store firewood away from the house.
This also reduces the number of hiding spots near entry points.
7. Inspect and Maintain Your Home Regularly
Prevention is always better than dealing with a full-blown infestation. Schedule seasonal inspections to check for signs of rodent activity, such as:
- Droppings along baseboards.
- Gnaw marks on wood or wires.
- Scratching sounds at night.
8. Call in the Professionals
While DIY methods can help with small problems, a large or persistent infestation requires professional attention. Rodents reproduce quickly, and without expert intervention, they can cause significant damage in a short time.
