Wingnut - I used Carpenter Ant/Termite Killer Plus from Bayer sold at Lowes. It's in a big blue bottle. It's concentrated but I didn't dilute. I used a decent sized artist brush and applied it into the cracks of the cabinet in question (TV) and also where the cabinet meets the floor and ceiling. Never saw any dead bugs. I also poured a ring of this stuff around the tires and all 5 stabilizers at the ground. It left a white residue on the stuff I painted but I think it will wipe off.
