Around here they cut them off and burn them. I'm interested in
any other
way to treat them. What is BT?


I suspect Craig isn't concerned with them in webs, but the
individuals that drop from the webs and start chewing on his
bonsai. It's the webs that burn, not the caterpillars. It
usually is enough to just break open the webs. Birds LOVE the
caterpillars.

BT is Bacillus thuringensis, a bacterium which infects
caterpillars. They stop feeding, some time after infection and
starve. It is "organic" in that it only affects targeted
animals/critters. Another version of BT goes after mosquito
larvae and is the ingredient in "mosquito dunks." There are
other strains that go after Japanese beetles, etc.

Read my "Bugs and Bonsai" on our website in the "Knowledge Base."

should have - Paul Bigelow Sears.
