When will I have robots that can chase invasive Argentine Ants back into the walls and ground where their queens live, and score non-toxic mechanical kills?
I've had good success around my house with cotton soaked in a combo of sugar, water and borax, then shielded from the pets by containing the cotton within a pair of used jar lids with holes poked in them. If that doesn't work, try peanut butter and borax.
Did this last year. The ants haven't even bounced back this year.
