Which is the best to use and where to buy in bulk.
Thanks, Sarge

Most of my stuff like that comes from Lesco/site one. They may or may not, probably not the cheapest, but they’re local and I can text the manager on his personal cell if I need something really early in the morning.

Question: I wonder if these heavy duty rat glue traps would be effective on squirrels in an attic? If you had several close together, would the squirrel get so wrapped up in glue traps that it could not get away? Dumb idea?

Dusty, to me it's a dumb idea. I don't even like them for rats and mice. Glue boards have a limited use, there are better options.

I use glue boards in fly lights and commercial monitors. I don’t use them in residential work.
