White Fly

The small insect making itself known this summer!

 Whiteflies are small white sap sucking insects 1-2mm in length and are often visible as they fly away when disturbed. They produce a sugary excretion called honey dew, which can directly cause sooty mould, a black mould that covers the leaves and branches of plants. With the removal of sap sucking pests, sooty mould will usually disappear.  Whiteflies damage plants, contribute to the spread of diseases, and can sometimes cause plant death.

White Fly breed rapidly in warm conditions and can therefore cause a lot of damage to plants in the summer months. We have definitely noticed a large number of infestations this summer!
