How do you keep tent caterpillars away?
Insecticides can be used on webs as a spot treatment. Apply them in the early morning or evening to concentrate the spray on the tents when the caterpillars congregate. During the winter, smother the eggs by spraying them with dormant oil, a highly refined oil that spreads uniformly and coats dormant insects and eggs.
Are tent caterpillars bad?
The good news is the tent caterpillar is not as damaging to trees and not as annoying to humans as the gypsy moth. The larvae often eat all the leaves off a tree. Although this damage is unsightly and worrisome, it usually only weakens the tree after three or more years of more than 50% defoliation.
What home remedy kills caterpillars?
