We have experienced Pest controllers that will identify the causes of your high population of wasps, (colours, temperature, plants, hedges, pool water condition etc.) in and around your house, and deal with the problem at source.
1) As a first treatment, we kill the wasps that are in the reported nest, and then (optionally) remove the nest. To prevent any other wasps returning and rebuilding a new nest in the same location, we treat the area in the immediate location of the nest with a strong wasp repellant and then coat the surface with an insecticide powder.
2) If the nest is inaccessible (e.g. in a wall, wall cavity or roof space) then an insecticide only treat will be performed to neutralise and kill the wasps in that nest. We may fit a mesh to prevent access by wasps not in the nest at the time. However it should be understood that a wasps nest is built to house wasp eggs, and these may hatch out 2 - 3 weeks after the treatment, so a second visit may be necessary. Also a wall may have, or the wasps may create more than one entrance/exit depending on the condition of the wall, but we will treat what we find at the time and provide advice.
3) If the nest cannot be found (due to the location being outside the clients property boundary) then wasp prevention and deterrent advice will be given.
Note: It is unreasonable to expect treatments 1) and 2) to provide a whole house or whole garden protection for air born pests (i.e to prevent any other wasps from making a new nest somewhere else) So as an additional option, should the client feel uneasy about the possibility of other wasps constructing another nest close to the original nest, then we also provide a repellent/insecticide treatment (chargeable) for the rest of the wall/roof tile area of that particular wall, wood timbers or that part of the house (where access is possible). Please inquire for cost. See also: Wasp Post Treatment Tips
Note: Wasps nests are a constant reoccurring problem (especially in the
Summer months) and can appear and grow in size very quickly. If the
post treatment advice has been followed and more wasps appear then we advise a
regular 3 weekly visit (booked in advance) to remove any new
