The Tomato Hornworms

Is there something safe that can be sprayed on our tomatos to rid us of these?

Bt...you can get it at any nursery here or HD, Lowes, WMRT. Look for the active ingredient Bacillus thuringiensis.

Sometimes called BT Worm Killer or Dipel Dust, although I don't like the dust much. Difficult to apply without a special applicator.

Anthing sprayable. The dust thing does not sound like fun.
