Spider Mites Miticides such as Kelthane and Pentac will control spider mites. Other insecticides with some mite activity include acephate, malathion and diazinon. Inseticidal soaps can be effective early in the season, before populations are high. Washing trees, especially spruce, periodically with a strong stream of water will keep spider mite populations at low levels. Pine Tip Moths Chemical sprays for pine tip moths need to cover the branch terminal ends at the time of egg laying and egg hatching.
Pheromone traps are available to determine the peak mating and egg-laying periods for most species.
Insecticides that will control pine tip moth include acephate, dimethoate, Bacillus thuringiensis, carbaryl and diazinon. The Nantucket pine tip moth has multiple generations, which may require two to four spray treatments over the growing season. NMSU and the U.S. Department of Agriculture cooperating.
