Pest Control

Pest Control

Don´t forget the basic prerequisites of thorough soil cultivation and reduction of weeds before resorting to insecticides. Pull up weeds and do not leave plant debris distributed about the place.

Take obvious safety precautions when applying insecticides, such as facial and hand protection. Make sure you only apply at the right times for edible produce; typically insecticides should not be applied close to harvest. Keep products well out of reach of children and animals. Also, keep containers well marked. Always, always, clean out thoroughly spray guns and receptacles if they are likely to be used for other purposes.

Please observe that BHC, frequently referred to below, is simply a shared use name for an organochloride pesticide generally containing DDT, dieldrin, heptachlor and chlordane. Check with your supplier that his or her product is genuinely BHC based, without any cancer concerns.
