Pheromones are also a possibility, of course. I’d certainly expect any other ants to follow an old trail. And, it’s not like you’d wash electronics down afterward.
Although that still doesn’t explain why they choose electronics in the first place - unless something in there smells like ant goodies to them. What got me in the first place was them choosing that one item when there was other stuff to choose from. I must’ve gotten 40 ants out of that one unit each time. They’re very tiny compared to carpenter ants or fire ants, and lighter in color.
I made a third trip over to that area, and they left the GPS and everything else alone - but it was a new house and had been gone over by a pest control person repeatedly before I ever arrived.
Can’t explain them eating the duct tape adhesive at all. Must have something sweet in it? They absolutely decimated it, though! If I wanted to trap some of them, I’d try that way.
