Wasp control concerns wasps that live in colonies containing many thousands of insects with a queen at the head. We call this Eusocial, describing how they live in a cooperative group.
Living in a group has many advantages, including defence. Once disturbed, wasps and hornets will defend their nests with a ruthless, efficiency that has to be both feared and admired.
Modern wasp control provides many different options for effective control, and these include.
Fumigants & Fogs
Insecticide sprays come in the form of aerosols and mixtures delivered with a pressurised sprayer unit.
Insecticide dusts are delivered with many different devices using compressed air of varying levels to provide the dust into and around a wasp or hornet nest.
Freeze sprays are also gaining popularity as a noo-nonsense, pesticide-free method of control for smaller wasps nests.
Each form of control has its advantages and disadvantages. Knowing which is going to be best in a given situation requires a full understanding of wasp behaviour, the limitations of your pesticides and delivery methods, and the safety limitations of each.
The most popular method of control is using insecticidal dust called Ficam D injected into the nest or around the nest entrance. Dusts use the wasps as a vehicle to carry the chemical into the nest, providing a thorough level of elimination in under an hour.
Huge nests or nests requiring instant control will need a combination of treatments. A typical procedure in an emergency might include a solvent or oil-based spray to coat and saturate the nest in a matter of seconds.
Control is easy if you have the training, equipment and experience to complete it safely – But never underestimate a nest! Stay safe.
