How to Control Spider Mites
Spider mites are a type of insect that prey on garden plants and fruits. These little creatures are related to spiders but suck the juice of plants rather than other insects. Spider mite infestations can happen quickly, making these pests a risk for foliage, ornamental plants and vegetable and fruit crops. If left unchecked, spider mites can cause enough damage to kill plants. Red spider mites are most likely to occur in greenhouses and conservatories, and they thrive in hot, dusty conditions.

Instructions for Controlling Spider Mites
-
1
Inspect your plants carefully, and inspect them often. Walk your garden, greenhouse or orchard several times a week to check for spider mites. Infected plants will look dusty and have small spider webs tangled in the leaves. Pay particular attention to the undersides of leaves. Always check new plants for spider mites and spider mite larvae before bringing them into your garden.

If you find pests or have an infestation, take steps immediately. Stop fertilizing heavily, to start. Plant-feeding insects such as mites prefer the fresh new growth brought on by heavy fertilizer. If you must fertilize your greenhouse plants, use a slow-release fertilizer.

Use insecticides to kill spider mites. Purchase these at a home and garden center, or make your own. Home remedies can be mixed up using dish or laundry soap and warm water.

4
Buy and use spider mite predators such as ladybugs and lacewing moths. These insects feed on spider mites and spider mite larvae. If you're going to use beneficial insects, however, keep in mind that they breed as well. You'll have to release a number of them into the wild consistently to keep your greenhouse from being overrun.
