I buy a bag of fireant stuff at wallyworld is red& black bag and kills the workers so the queen is screwed
and I use some butter containers with boriac acid& peanut butter and poke holes on lid so they go in& eat and die.I duct tape the lid on so squirrls don't eat it.but had same results preplaceing peanut butter with butter& sugar...but peanut butter holds up better with the heat in TX
I had fun burning some though...sprayed some lighter fluid on on a book of matches I lit.roasted fireants...yummy
