| I've been using the OVE worm tea for about 14-16 months and I have NEVER had any pests. I spray a few times a week and occassionally water all my plants with the worm tea. Even when my coleus plants were swarming with mealy bugs, the orchids were safe. Not sure what this worm poop tea does scientifically, but obviously it keeps the critters out and that's good enough for me.
Safer's7 soap works great, Bayers 3 in 1 spray and I think that any mild soap solution you concoct will probably work as long as you keep abreast of the problem and respray a couple times a week. As previously mentioned, Dr Bronner's Liquid Peppermint Castile soap is also great stuff for making your own home made soap sprays. For some reason, bugs don't seem to enjoy peppermint! |
