Unless you have a pet rat, you probably don’t want one in your home. Most people know rats can carry a number of diseases that can be transmitted to humans — some are even deadly. On top of that, rats have monophyodont teeth that never stop growing, so they constantly chew to wear them down. That’s why they can gnaw through soft metal, electrical wiring, and more. It’s no surprise they can do serious damage to a home — and even to car wiring.
Are rats still a problem in the summer months?
Yes. People often assume winter is the riskiest time because rats look for warmth and food — but hot weather can push them indoors too. When it’s very warm and dry, food and water outside can be scarce. Your home has both, plus cooler shelter, so summer becomes just as attractive.
Once inside, rats can tear up belongings and easily get into food packaging. Nobody wants to eat at a table that’s had rats running across it all night.
How do rats get inside a home?
Rats are mostly nocturnal, so they’ll scout your house at night for any weak spots. Because of their long, flexible bodies, they can squeeze through tiny gaps — smaller rats can get through a hole about the size of a quarter. It only takes one opening. Small cracks, gaps around pipes, broken vents, or roof intersections all look like front doors to a rat.
If you have one rat, you probably have several.
Rats are social, smart, and reproduce quickly. A single male and female can turn into up to 2,000 rats in a year under ideal conditions. That’s why a “small problem” can become an infestation fast — the longer you wait, the harder it is to control.
How can I protect my home from rats?
Start outside. Walk around your home and check the foundation, siding, and utility penetrations for cracks or gaps. Seal small cracks with exterior caulk. For larger gaps, push in steel wool and seal over it — rats don’t like chewing through it.
Don’t forget the roof. Many rats are excellent climbers — that’s where “roof rat” (Rattus rattus) comes from. They can get in through roof cracks, eaves, or damaged flashing. Repair those areas so they can’t drop straight into your attic.
Also remember: a rat anywhere on your property is a rat that can end up inside. People often ignore an outdoor rat sighting, but it’s better to act early.
Traditional controls like rodenticides work, but they carry risks to pets, kids, and wildlife. Snap traps are cheap, but they don’t always kill instantly.
A safer option is a toxin-free, quick-kill trap. The Goodnature A24 Automatic Rat & Mouse Trap kills instantly and then resets itself. It’s powered by a CO₂ canister, so it keeps working without you having to rebait or rearm it every time. Outdoors, scavengers often clean up the remains.
