Why Rodents Enter Your Home in Winter (And How to Stop Them)

💡 Quick Answer: Every fall, homeowners across the USA notice something: rodents start showing up inside. This isn't a coincidence. Understanding why rodents enter homes seasonally is the key to preventing — or stopping — an infestation before it gets out of control.

Key Tips & Information

Mice can squeeze through gaps as small as 1/4 inch (the size of a dime)
Rats can fit through holes the size of a quarter
Common entry points: gaps around pipes, damaged soffits, garage door gaps, foundation cracks
Rodents seek warmth, water, and food — your home provides all three
A female mouse can produce 5-10 litters per year with 5-6 pups each — act fast
Steel wool + caulk is effective for sealing small gaps (rodents can't chew through steel wool)
Snap traps remain the most effective DIY rodent control method
Remove outdoor food sources: secure bird feeders, compost bins, and pet food

When to Call a Professional

Professional rodent control becomes necessary when: you hear scratching nightly, find droppings throughout the home, notice gnawed wires (fire hazard), find a nest, or DIY trapping isn't controlling the population. Our exclusion services find and seal every entry point permanently.
