Dealing with wasp nests can be a tricky and dangerous undertaking. But store-bought wasp killer products often have little effect on one particular kind of wasp nest. If you can’t physically see the wasp nest structure store-bought products will not be effective. This includes ground nests, nests in retaining walls, trees, foundations, etc. The store-bought products will not be able to reach deep enough into the nest to affect the Queen. The only wasps that will be affected are the workers that fly in and out of the nest. Our professional-grade products keep the wasps alive long enough to carry the product deep inside the nest. Once inside it spreads to the entire colony killing the Queen in the process. This can take between 14-30 days depending on the size of the nest.
