What did you use for bait in the squirrel trap?
Corn on the cob - a piece a couple of inches long. You can buy a bag of these for feeding squirrels. They’d been coming to corn on the cob set out on a nail on the fence. Once we moved it to the trap, they knew what it was and went in fairly easily.
The other thing I found that works really well in a regular trap with a trigger plate is a cracker spread with peanut butter & black oil sunflower seeds on top. I have not tried this in the squirrelinator, but I’m guessing it would work, especially if the squirrels were raiding the bird feeders & were familiar with sunflower seeds. I think the PB smell helps attract them & they love the sunflower seeds.
