The Attack Spiders worked just great. I hung them up and watched from a distance. A short time later a pecker tried to land and enter his nest, as soon as he was close the spider dropped. He took off and I haven’t seen any since nor signs of more holes started. I know they haven’t been back as the battery power is still up. If they were persistent, the batteries would be down or dead .Now all I have to do is patch the holes. Thank you.
