Oak Processionary Moth Treatment

Oak Processionary Moth Nest Treatment

At ATS, we use an environmentally friendly chemical and specialist machinery to undertake the job effectively, correctly and with minimal risk environmentally and ecologically. This coupled with our trained, competent and experienced operatives therefore ensures a professional and efficient job.

The chemical we use is Dipel DF. Dipel DF is living bacteria Bacillus thuringienis which when applied is ingested by the caterpillars. The bacteria breaks down the alkalinity of their stomach which leads to paralysation of their digestive organs and the caterpillar therefore starves. Dipel DF is one of two chemicals endorsed by the Forestry Commission as a chemical applicator, the other one being Dimlin Flo.

At ATS we exclusively use Dipel DF as it targets caterpillars solely and can break down easily within the food chain. Also, it is environmentally and ecologically friendly. We apply the chemical when it is most efficient (between the 1st and 3rd instar (growth)) stages which is early May to June. To apply the chemical, we use two methods depending on the site and the degree of infestation. For large sites and multiple trees, we use our specialist 4X4 Ultra Low Volume spray unit which can reach lengths of 30m. Imported from Italy and used during OPM treatment works in 2013, we have found this machine both invaluable and incredibly efficient. The Ultra Low Volume feature therefore produces a dramatic reduction of water and chemical usage and in addition to this, the spray unit is electrostatic. This means the treatment is slightly positively statically charged thus reducing drip of the chemical once applied and again uses less water and chemical. For single spot treatments we use a knapsack mister worked by an experienced operative. ATS adhere to the correct use of the correct Personal Protective Equipment and we aim for an efficient, environmentally and ecologically friendly treatment unique to the situation.
