Did you hear that?
That tiny, squeaking, scratching noise in your wall? Or overhead in your ceiling? That tiny noise that gives you the creeps and won't let you sleep at night for fear of something suddenly appearing in your bed? And yes, if you are hearing that noise mostly at night, then you probably have a rat. Or two. Or even dozens.
Did you know that a female rat can go into heat days after she has a litter? As a result, just a few rats can grow into an infestation in no time. Rats do not like to be out in the open because of predators. They prefer dark, warm, safe places to hide such as your attic or walls. So by the time you actually see a rat, all the good places to hide in your home are probably full of his cousins. Rats are kind of like potato chips. You probably won't have just one!
