Tool or Gardening Product
Spinosad is a natural product derived from one of the beneficial soil microbes known as actinomycetes. It is low in toxicity and works especially well against leaf-feeding pests such as caterpillars and some types of beetles. It is most effective against those fall webworms now plaguing our pecan and mulberry trees, if used before the caterpillars grow to over about 1/2 to 2/3 inch in length. Break up the webs prior to spraying so you can get the product to the foliage where the caterpillars are feeding.
