Re. misting.

I once drenched pots with malathion for the fly, and all of them came to the
surface coughing. I thought right I can blast them with something else now
and used an aerosol, a household flea and fly spray containing pyrethrin.
Boy it was good control and really successful for the fly. Sadly all the
seedlings died as well, it would seem that the plants were phytotoxic to the
butane propellant.

Good idea, dreadful mistake. Next time I'll be more careful. Actually I am
hearing a lot of people are great success using insectivorous plants for
control.

Best Wishes,
Dave
