im dont no if it works but a good friend of mine and also an out door grower told me out side thay hang a bar of sope next to the plant to keep the insects way try it out
Pull out the artillery! Id say a few m80s and a nickles worth a' c4 oughtta do the trick... yep. dont be shy, just stick em in and light em up! try spraying a light soapy water solution on the top of the soil, see if this works. dr bronners peppermint soap would probably kill em instantly now that I think about how it feels like its burning a hole in your head while shampooing in the the shower... i have not tried it though to be able to tell you if its safe on a plant or not... i just dont know. take care.
