I wanted to share my experience .My plants were overcome by these pests. I have birds and I didnt want to use any poisons .As with the rest of my yard because of my animals and fish .Sooooo..... I took quite a few ciggarette butts and soaked them in hot water for a few hours.strained off the water into a quart spray bottle then added 1/2 cup of rubbing alchahol ,1/4cup listerine mouthwash.a squirt of dish soap a vola!! I sprayed down the plants every other day until they were all gone! whooo hoo. It worked .It doesnt smell too great but once it is dry you cant smell it anymore.
