An increasing number of gardeners and allotment holders are choosing not to use pesticides, but electing to grow organically. Biological pest control is totally safe to pets, children and the environment. The predators used occur naturally in the U.K. the only harm done is to the pest! Even for those willing to spray pesticides, choice is very limited and often predators and parasites help control a number of garden pests without the need to use pesticides.
