The Q&A Archives: Green Bugs

Question: We are having a problem with I believe aphids on our perennials muffet daisy and the like they are small green worms nibbling up the leaf is there such a thing as a natural pesticide or a plant that drives them off or prevents them ?

Answer: Aphids are small soft bodied sucking insects that tend to congregate in the growth tips of plants. They can be treated with insecticidal soap or knoscked off with a stream of water from the garden hose. Based on your description it does not sound like aphids in this case. It might be the larvae of a beetle of some kind or some type of moth or butterfly. You can try a neem based spray or, if it is truly a caterpillar, Bt (Bacillis thuringiensis). Hand picking may also be effective if you only have a few plants.
