The jet spray can reach a nest up to 1.5 metres away. Like a fly spray it kills the wasps on contact quickly minimising the threat of stings. The residual sticks to the nest making it unusable by other wasps. It has a water based formulation which is easy on plants and reduces staining. Managing wasps in the garden is great for the bee population. Wasp-X can be used on nests inside buildings and outside in the garden and on building surfaces.
