bag worm infestation
greetings, i have a question regarding a bag worm infestation in our neighborhood. do you or does anyone come to spray the infected area? the worms are in the canopy level of the trees and are too high reach. could you point me in the right direction if you do not offer this? thanks for your anticipated help,
Baltimore County Maryland
We suspect you are seeing tent caterpillars. There are very high numbers of them this spring. They are a native caterpillar of a moth. Since they evolved with native trees, they normally eat the leaves (primarily of wild cherry trees) but do not kill or damage trees. They do not bite or harm humans. They do not merit spraying by the State or counties, but there are a few things you can do if you don't like the look of them. Here is information from our website: http://extension.umd.edu/hgic/eastern-tent-caterpillar-trees Keep in mind that they will disappear in a week or so and their nests will disintegrate. On the plus side, they provide a huge food source for birds.
Incidentally, bagworms don't make webs, they make little bags that don't show up until later in summer. Here is what they look like and how to control them: http://extension.umd.edu/hgic/bagworms-trees-and-shrubs
