Although they may look gross and off-putting, the webworms are an important food source for birds. Fall webworms are moth caterpillars that are native to North America. Webworms can typically be seen later in the summer, munching on a whole variety of deciduous trees such as maple, elm and poplar. Unlike other caterpillars, webworms like to live in large communities. One way to treat webworms is by using pesticide, one that specifically targets caterpillars so as to reduce harm to other types of insects.
