At least your squirels are dumb enough to get caught in the rat traps.
I have a red squirel, who I have named Lucifer... cause he is a little devil.. He is in the crawlspace under the house, there is no way to seal up the house or basement/crawlspace. Lucifer chews his way into the house from below. and has ignored the rat traps the live traps, he did leave behind some fur on one of the 'glue sheet traps'. But that is it... He is so damned smart!!
He gets into the Laundry room where I keep the dog food and chews his way through any kind of plastic container to get to the dog food. and he Knows when the new bag of Purina shows up, he'll be there that night and chew a hole in the new bag.
I finally found a short galvanized trash can that I store the food in, but Lucifer has even been gnawing on the lid of the galvanized can!!
In the live trap and on the rat traps I've tried, peanut butter, dog food, marshmallows, different lunchmeats. and every other concoction I have heard of. Right now I have some dog food stuck to peanut butter on a dowel over a five gallon pail of water, hoping he will go after the dog food, and fall into the pail, and won't get out..
He generally just ignores any traps or placed food, he likes dog food in the new bag, and the stored dog food in the plastic pail, that he has chewed holes in.
I've shot several of his cousins eating bird food in the breaze-way, but have never seen Lucifer in the laundry room only seen the aftermath of his visits...
any ideas on bait or traps??? I'm about to leave a pan of ethylene glycol in the crawlspace for his 'pleasure'.
