When the queen dies, the colony dies. When using aerosol treatments, spray the nest to immobilize individual workers as much as possible, which helps you get to the queen.

If a liquid treatment does not reach the queen, applying dust at the entrance of the nest will facilitate movement of product into the colony, eventually killing the queen.

When nests are located in foundations or voids, pest management professionals (PMPs) usually will need to drill holes through the foundation and fill the void with foam containing an active ingredient designed to transfer from one insect to the next.

Remember, killing the queen is imperative.
