How to avoid the reproduction of the black fly
According to EP, to avoid the reproduction of the black fly, they apply spray treatments biocides that affect the larvae of the black fly aimed at reducing their presence. These larvicide treatments aim to reduce the number of larvae present and prevent their transformation into pupae in the water, which are not affected by the larvicide treatment, and thus prevent their passage to adult insects.
As a complement to these treatments are carried out clearing and pruning of vegetation which is in direct contact with the water layer, since it serves as a support for larvae and a refuge for adult specimens, according to information from EP.
