Hi, Bob. One thing you might not hear is that they have many pests, too. If one does the arithmetic, he would expect to be innundated next year. Not so. Very small increase has been my experience. Considerable attention to detail is required. That said, they are excellent pollinators which stay relatively close to home. In Seattle, WA, with climate similar to UK, they emerge in March and are all dead (except for eggs in cells, of course) by early June. This duplicates the period needed for all pollination except late berries and many ornamentals. They are lots of fun to watch, like to bask on sunny surface and won't sting without receiving a request in writing. Dan __________________________________________________ Do You Yahoo!? Yahoo!
