Heh heh! Well, depending on what it is eating your plant, you can use several items...Diotomaceous Earth cuts the legs of some critters, Lady Bugs eat some, BT makes worms sick, then you can use the big guns, the last straw, so to speak and it's natural pyrethrins...which are very toxic to *every* insect but are not toxic to humans. It kills everything, though...earthworms, lady bugs, butterflies.
All good information...I'll be bugging you again someday, for sure! ;-) Have to wait until I get a bit of earth...
