No, our traps are designed to trap bed bugs without the need for any added substances or powders. However, some customers have found success adding small amounts of Diatomaceous Earth (DE) powder or soapy water to the moat of the trap. However, when adding substances to the traps, it is important to ensure it is done in a very small quantity and only at the bottom of the well in order to avoid creating a means by which trapped bugs may crawl out of the trap.
