Caught a sparrow, good thing I didn’t see it. They got it loose, but it lost feathers. The rat only stuck one foot on it and the got loose. We picked them up and threw them away. Not the way I really want to view some creature exiting. We did , however, use bait traps and this method has worked to our best knowledge. The bait disappeared for weeks and then stopped. The rats were eating our equipment, clothes, cushions, fabric, we had to do something fast and the bait traps worked.
Due to road construction we have a rat problem, I put 5 traps down under and in back of a chair in the living room where I knew the rat had been. In the morning all 5 traps were stuck together at various angles in front of a shelf in my dining room. Outside of a few tufts of fur there was no rat to be found. Save your money!
