The Wilco squirrel trap arrived Thursday and I immediately set it. I had been putting out a few walnuts for three days before the trap arrived to get the rodents use to a meal. On Friday a squirrel had entered the trap and after the meal managed to force open the top door. The aluminum hooks are cheesy and just stretched to let the animal out. So I reset the trap with nuts and put a sledgehammer on top of the door. By the end of the day I needed to dispose of the first victim. The trap works as advertised.
