Eastern Tent Caterpillars

Now is the time to remove the egg masses of the Eastern Tent Caterpillars. They will begin to hatch as the tree buds open. Look for small swellings on twigs. They can be easily pruned or scrapped off. Look for egg masses on apple, cherry, plum, crabapple, or other flowering fruit trees. For more information, look under Extension bulletin (A 2933) and can be found at http://cecommerce.uwex.edu/showcat.asp?id=15.


Tent Caterpillar Hatching

Carpenter Ants

Spring always brings ants along with flowers. If you have been seeing medium to large black ants for the last 2-3 weeks it strongly suggests that you have a carpenter ant colony in the home. Activity seems to peak in April and early May and as food becomes available outdoors the ants number may drop. The best control is to find the nest, but some of the new ant baits made specifically for carpenter ants are also very effective. For more information go to http://www.entomology.wisc.edu/entobltn.html and click on the controlling carpenter ant bulletin.

Insect ID

Adult carpet beetles are most active in the spring. To help you identify the critters you find in your home we have expanded the insect ID section.

Go to http://www.entomology.wisc.edu/insectid/index.html.

We will begin to work on the outdoor insect pest section this summer.
