Getting rid of rats means fighting on two fronts at once. You trap the rats inside while cutting off the outdoor shelter and food that keep the population alive. Rats are smart, suspicious of anything new, and they breed quickly, so a half-measure almost never works. What clears them is careful trapping, sanitation, and sealing, done indoors and out together.
Quick answer
To get rid of rats, trap them inside with snap traps on their travel routes while cutting off outdoor food and shelter, then seal entry points with steel wool and caulk. Rats are wary and breed fast, so trapping, sanitation, and exclusion must happen together to last.

Why Rats Are So Hard to Clear Out
Rats are cautious animals. Unlike a curious mouse, a rat treats anything new in its space as a threat, so a freshly set trap can sit untouched for days. They also breed fast. One female can produce several litters a year, each with a large number of pups, and those pups can reproduce within a couple of months.
They're tough, too. Some rats gnaw through hard materials, climb walls, swim up through pipes, and slip through gaps far smaller than you'd expect. That's the reason getting rid of them takes a coordinated push instead of one quick fix.
The Health Risk That Makes Speed Matter
Rats are more than a nuisance. Rodents are known to spread dozens of diseases worldwide, and you don't have to touch a rat to be exposed. Contaminated food, dried droppings that break into airborne particles, and parasites like fleas and mites that ride along on rodents all put people and pets at risk.
Contamination spreads as the population grows. So acting at the first sign of rats, instead of waiting things out, limits both the infestation and what your household is exposed to.
How to Get Rid of Rats Inside
Indoors, trapping is the safest method you can control. With rats, two things make the difference: patience and placement. They avoid the unfamiliar, so rushing it backfires.
Here's how to set yourself up to actually catch them:
- Use sturdy snap traps sized for rats, set flush against walls and along the routes they already travel
- Place traps where you've spotted droppings, gnaw marks, or greasy rub marks
- Leave traps unset and baited for a few days first so wary rats get comfortable, then arm them
- Bait with something high-value like nut butter, and wear gloves so your scent doesn't warn them off
- Check daily and reset right away as long as activity continues
Getting Rid of Rats Outside
The rats outside are the source that keeps refilling an indoor problem. Ground-dwelling rats burrow near foundations. Climbing species nest in attics, vines, and trees. Treat the yard and the structure as one job.
Make your property a lot less appealing:
- Clear woodpiles, brush, leaf litter, and clutter that give rats shelter near the home
- Trim branches and vines back from the roofline so climbing rats can't bridge into the attic
- Secure trash bins with tight lids, and pick up pet food, fallen fruit, and birdseed
- Get rid of standing water and fix outdoor leaks that hand rats a drink
- Keep grass short and clear debris along fences and foundations where rats like to burrow
Seal Them Out for Good
Trapping and yard cleanup won't hold if rats can just walk back in. Exclusion, meaning you seal every workable entry point, is what makes the results stick. Inspect the foundation, the roofline, vents, and anywhere pipes or wires pass into the home.
Pack gaps with steel wool, which rats can't gnaw through, and back it up with caulk on small spots or hardware cloth and metal flashing on bigger ones. Add door sweeps, fix damaged screens and vent covers, and close the gap under the garage door. Rats gnaw to widen openings, so a quarter-inch gap you ignore today can be a doorway tomorrow.
What to Skip, and When to Call a Pro
Skip the rodent poisons around your home. They put pets, kids, and wildlife at risk, and a poisoned rat often dies inside a wall. Then you're left with a strong odor that's hard to find and harder to remove.
Rats are smart enough to learn your tactics and route around them. If your trapping stalls out, the activity keeps coming back, or you simply can't find where they're getting in, call a licensed local pro. A good exterminator can identify the species, trap with a real strategy, finish a full exclusion, and keep watching to confirm the rats stay gone.
