Pests often enter your crop using pets for transportation. Do not leave your pets in the garden. Their fur also builds up on the sticky buds.
Clothing worn outside may contain parasites. Even a single pest can be a vector for a fast growing colony.
Before entering, wash your hands and dress in freshly laundered clothes.
Before letting a plant get into a pest-free garden, quarantine it and use a pesticide or an fungicide spray or dip to make sure.
