    Oleander Aphids are a MAJOR problem growing milkweed. Do you know if the Worm Castings have any effect with reducing or eliminating such concerns?

      We, Central Iowa Organic Fertilizer, have had quite a bit of feed back information on pests and Earthworm Castings. We have read a lot on the same subject. It should be noted that we do not have hard science on this topic and are relaying what our customers have told us and what other users of Earthworm Castings have written on this topic.
      There seems to be substantial success in pest control by making and using “Castings Tea”. The instructions for making Castings Tea are on our bags and website:
      After making the Castings Tea, thoroughly spray your plants. The nutrients from the Tea will be taken in by the leaves and from the ground where the Tea drips off the plants so the plant is being fed from two places at once. The Tea seems to also act as a natural insect repellent.
      One customer told us that he sprayed his crops with the Tea and the farmer just across the road did not. Japanese Beatles destroyed the other farmer’s crops, but the crops using the Castings Tea were untouched.
      The Castings Tea is beneficial as a feeding and fertilizing method and is reported to be a successful insect repellent. The key in the repellent seems to be the application of the Castings Tea. Our castings are OMRI Organic Listed, have no chemicals, and are safe for people and pets.
      Thanks for your interest in Central Iowa Organic Earthworm Castings.
