Issues In Choosing An Insecticide For Tent Caterpillars
Because tent caterpillars spend most of their time safely hidden in their silken tents, they are rarely harmed by chemical insecticides which cannot penetrate the tents. The caterpillars are most vulnerable when they have recently hatched and before they start to spin their webs. In some cases, when other trees in an area need protection, a professional arborist will know when to spray a tree and what insecticide to use.
