How to Rid Spidermites From Fruit Trees

Overview

Tiny in size, the two-spotted spider mite can wreak major havoc on a gardener's investment of fruit trees. Fortunately, the pests don't have to take permanent residence. Whether you prefer to introduce a natural or chemical solution, there is a means to effectively get rid of spider mites from your fruit trees.

Step 1

Spray the infected plant with a water hose. Thoroughly spray the plant, including the underside of the leaves. Be careful, however, not to cause additional damage to the tree by using a stream of water that is too forceful. Spider mites do not like cold, wet environments. Treat infected trees, daily, for 1 week.

Step 2

Introduce Phytoseiulus persimilis, a natural predator of the two-spot mite, into the environment. (Purchase phytoseiulus persimilis from a local nursery or through a mail-order company that supplies beneficial bugs.) Release the Phytoseiulus onto the leaves of the infected plant when temperatures are between 50 and 90 degrees. Observe activity of the Phytoseiulus, which smells its prey, then quickly devours it over a two-to-three-week period.

Step 3

Spray WiltPruf or UltraFine according to the manufacturer's directions to remove spider mites from fruit trees. Rose Defense Spray will get rid of the pest but is gentle on plants. (WiltPruf, UltraFine and Rose Defense Spray are readily available at any garden center.) Make a solution of isopropyl alcohol, water and a few drops of dishwashing detergent for a treatment that is less harsh but still effective. Spray the solution early in the morning or late in the day for the best effect.
