Control Measure for Tent Caterpillars
Higginator is right about bacillus thuringienis kurstaki (BT), which is also effective against gypsy moth caterpillars. However, keep in mind that BT kills ALL caterpillars, even the good ones, so, first of all, know your caterpillars. Second, read up on the product because it is most effective when used in the early stages (instars) of the caterpillars' lives.On Umbra on tent caterpillars posted 1 year, 6 months ago 14 Responses
