Control red spider mites on your plants in greenhouses, conservatories or on house plants using this speedy predatory mite
The Problem : Glasshouse red spider mite. These sap sucking tiny pests are , despite their name , a greenish yellow colour with two dark blotches of their backs. You usually need a magnifying glass to spot them beneath the plant leaves and causing tiny flecks on the leaf, which, in extreme cases turn bronze-brown, crispy and then die. There may also be silken webbing present. Red spider mites love hot, dry conditions and hate wet feet.

** (Larger, economy pack of 2,000 predators also available)
NB : If you have used chemical pesticides in the greenhouse/conservatory/frame/house the residues they may leave may harm the beneficial ones you are introducing ! Please Note :
*Chemicals such as soaps, fatty acids will kill beneficials if applied to them but once dry it is safe for them to walk
across treated leaf surfaces.
*Pyrethrum - Will kill beneficials if applied to them and lasts about 3 days on treated surfaces.
*Neonicotinoids (imidacloprid, thiacloprid, etc.) These are very persistent and adversely affect a wide range of creatures, even if used as a soil drench rather than a spray they become systemic and will poison predators eating pests that then feed on treated plant.
