NOTE If you are an avid indoor gardener and want to get into biological insect control like the experts, get yourself one of these packets containing Amblyseius cucumberis, a microscopic predator that loves to chomp on thrip, a common plant sucking insect. They last up to 28 weeks. Place packet near the soil, the predator ( invisible to us) crawls out and eats the thrip like mad
