An exterminator used this product on the entry ways into each room of our house. Was that correct? And how long it last once applied?
Eco PCO ACU is a contact kill insecticide that does not provide a lasting residual. Insects must be contacted by spray to ensure 100% mortality. Once the spray has dried it will no longer be effective.
