The Rentokil Wasp Killer is a potent, ready-to-use insecticidal dust supplied in a 300g puffer pack, specifically designed for treating wasp nests. The powder formulation is ideal for application directly into the nest entrance hole or other hard-to-reach areas, ensuring the lethal active ingredient is carried deep inside the nest by foraging wasps. This method ensures the entire colony, including the queen, is killed, providing effective and definitive control of the infestation. It is a highly effective solution for eliminating wasp nests quickly and safely, providing long-term relief from these dangerous pests.
