How do you get rid of cochineal?

Answer 1

* If you catch the problem in the very early stages with just a few white tufts, you can spray them off with water. Be sure to do a thorough job and check back every few days. Repeat as necessary.

* If the problem is more advanced, you probably will have to use chemicals. We find Malathion to be adequate. Mix to the recommended strength for ornamentals -- cactus is usually not listed on the label. Add a little liquid soap to the mix so the water/Malathion stays on the plant better. Spray thoroughly paying special attention to the places where the pads or joints come together. This process should be repeated seven days later and again fourteen days later to catch the bugs you missed AND to get the newly hatched cochineal that were protected by egg cases. You will know your treatment is successful when the white tufts turn a dingy gray and squeezing them does not produce the crimson stain.
