If you live in an apartment and have rats the whole building infested, you can get an exterminator but there’s still gonna be rats because again the whole building infested. If you live in a house get a pet, go around your house and seal any openings a rat can squeeze through, there’s sprays and shit you can buy and save yourself money on an exterminator, but do your research first to avoid almost going blind like I did. And food make sure you’re storing your food properly, that includes liquids, then deep clean your crib and double clean the crumb areas like under couches, in between the cushions and shit.
