Red spider mite

Symptoms

Leaves become speckled, as though covered with hundreds or thousands of little dots. A badly infested plant becomes covered with fine webs.

Cause

A little mite (1mm long) which sucks the sap from the leaves. Despite the name the mites are red only during the autumn and winter months when they are hibernating.

Harm

Sucking out the sap weakens the plant. If the infestation is bad, so much sap can be taken that the leaves can dry up and fall off. House and greenhouse plants are most often affected but they can also be a problem outside in hot, dry summers.
