Keep pests off your plants without sprays using non-chemical pest exclusion products. Physical barriers such as fine insect netting, fitted net covers, fruit protection bags and sleeves, bird netting and copper slug barriers stop pests reaching crops in the first place. Exclusion is especially effective against fruit fly, cabbage moth, birds, possums and snails, and it means no withholding periods before harvest. Cover crops before pests arrive, seal the edges well and combine with traps to monitor what is around.
