Leaving one aphid alive can result in the production of a new colony very quickly. In addition, the use of insecticides kills the beneficial insects that normally keep aphid populations under control. As with all pesticides, read and follow all label directions and precautions. Mites are not insects, but are more closely related to spiders. They tend to be more of a problem during hot, dry periods.
Mites are extremely small and can barely be seen without a magnifying lens.
They have piercing mouthparts with which they puncture plant tissue and suck plant sap. Early damage is often overlooked until damage is more severe. With heavier infestations, symptoms include distorted leaves, and withered and discolored blooms. In addition, fine webbing can be seen on flower buds, between stems and on the undersides of leaves. Spider mites can be removed by spraying plants forcefully with water.
