Easy way to test this is to get a granola bar in the silver tin wrapping, open it up and put it under your bed as you sleep. We did this to a guy from India in my old army unit when we stayed in a train car in Fort Irwin (it was a town mock up, train car was a building). The guy was 6'6 and heavy, highly educated (went to college in China), and had a fear of rats. One of the Mexicans put the granola bar opened up on the floor and we heard the rat take it back and forth across the wooden floor of the train car all night long. We could hear him sqeal and curse out in Hindi all night long, was so funny.
I don't recommend poison pellets bejng left out, because they will either due on your floor, or in your wall. You'll either have to pick them up or smell them. Glue traps exist. Sprinkle some food on them.
@DeWayfarer when I got a pet bunny, all three remaining cats were feral born, but one came in as a little kitten from outdoors (black female). The other was a long time black feral male but quite friendly to humans. Third.... he wasn't born feral but spent alot of time outdoors because successive owners outright hated him (big cat, was trained by first owners to hide and jump on their backs, and he did it with claws from hidden spots) and kicked him outdoors homeless.
I had the bunny in a big dog cage, with kitty litter on either side. She could hide in the middle out of range of any swipe, and plenty of places to hide. I was slow to clean up after her poops to let the smell overpower the cats litter smell. They all got used to her, except the jumping cat who I did not really like. First time I introduced him he tried to kill her. Only time I ever heard that rabbit make a noise was in the middle of the night when it attacked the cage, but I lept up immediately from the couch, other two cats sitting on the couch with me. That bad cat died from a stomach ulcer from local city water a week later (lots of people were getting it, not me because I didn't drink the water and I switched the survivors over to bottled water like me).
I would have to sit each cat down and pet it saying Nice Nice, then take their paws and pet the bunny saying nice nice, then them again, on repeat. The black male cat liked delivering live mice to me. I kept one he found in the winter time in a cage for a week until it died..... gave it plenty of food and water, had no injuries. Guess being around cats freaked it out.
@Colonelmustardseed I found fly infestations are solved by covering every source of light, including windows, and then opening the microwave. The light turns on, flies enter microwave. You run it for a minute, open it. They fly out, but die in a short while. Repeat. Much quicker killrate than flytape. But still use flytape.
I had a fly infestation as a kid (can't remember why, was in the basement) and also as a kid a cricket infestation (they fell from the sky like rain in central valley, california and infested everything indoors and outdoors). I would get sent into the laundryroom, told to kill all the crickets and would just swing a wooden broom at them for hours waiting for their sounds to stop.
this may seem a little weird .before my wife died she was all ways giving me money to keep for her. if she had the money she would spend it .after she died I would find $10 some times $20 dollars extra in my wallet .after a few times this happen I started counting my money before bedtime .but the extra money still there. after few months it stopped ..still bothers me .that was 20 years ago.
