Treat Woody Landscape Plants

If you look closely at your trees and shrubs you may find a number of insects have become active. Now is the time to look for and treat for Gypsy moth, Pine needle scale, European pine sawfly, rose slug, Euonymus webworm, honeylocust plant bugs, and tent caterpillars. Specific information on many of these insects and general recommendations for woody landscape plants are published in Extension bulletin A3597, Woody Ornamentals Pest Management in Wisconsin, and can be found at http://www.entomology.wisc.edu/entobltn.html.

Deer Ticks

Deer ticks have been coming into the lab in numbers. With people out hunting turkeys, morels or just enjoying the spring woods you need to keep your guard up. There were over 1,000 cases of Lyme disease last year. It takes the female deer tick 36-48 hours of feeding to transmit the disease.

Carpenter Ant Nest

This is what a carpenter ant looks like inside a log. Notice they do not eat the wood but make small cavities to raise their young. We will be reaching the peak time for swarming winged forms in the next 2-3 weeks.
