We have had a rat infestation for quite some time now. Only successfully trapping 4. We thought we got rid of their nest, but now we are getting worried. Tonight we saw 2 rats chasing each other across the yard and another sat and watched. We set up many traps outside after seeing this, even the last resort glue trap. We took a flashlight and saw many rats, including an enormous one that ran across the yard whenever we turned off the light. But rats aren't the only problem, we saw some mice in our wall vines, meaning we have rats AND mice!!!! Later we checked a trap with poison bait, we hadn't checked it in a while because there was no progress. We found it half-eaten, yet no signs of dead rats or mice! I think are after chicken food because we found poop where there was old feed, but we moved the feeder inside with only a small amount of it leftover outside. They used to eat peaches from our peach tree, but they just finished! Why so many animals, what are they looking for?! I'm actually surprised there are no owls helping. Last time it was all just mice and there was an owl on the scene immediately. Does anyone know how to fix this problem or have any idea why they're here in the first place?
