George from Rosemead, Ca writes,
What is the most effective dilution? 1% or 2% or as shipped?
TERRO-PCO Liquid Ant Bait can be diluted with water to obtain a 1% or 2% solution of Borax. Such a dilution is helpful when you plan on using a substantial volume of TERRO-PCO Liquid Ant Bait in a baiting program designed to control very large multi-queen and multi-colony ant infestations. We recommend using the lower usage rate at first so more of the ants are able to get back and forth between the bait and the colony before they succumb to the bait.
