Look around for any food sources that attract pests. Get rid of them or close them in air tight containers.





You can buy traps and bait them with peanut butter. Rats love pizza, BTW. They also have a taste for potato chips. I've done research on rats since 1978.





The problem with poison is that they can crawl into some inexcessable place and die and then smell really awful.
The ultrasound repellants do not seem to be too effective. Exterminators tend to use poisons.
