In my May 7th post, I discussed the return of the western tent caterpillar to Kitsap county. They've been growing in size and damage. I've noted no catastrophic damage as yet...that may come next year. But the little buggers do seem to be starting to crawl away from their hosts trees now, possibly looking for a place to pupate. I've seen them crawling around. One showed up on my recycling bin (see photos).
And a note for those of you wanting to use Bt to control these caterpillars: It's too late. Bt is really only effective against very young larvae and by this point, the caterpillars are too old. Mid April would have been a good time to spray with Bt. But don't worry, they'll be back next year. Remember: Mid April.
