How to Get Rid of Woolly Aphids


Woolly Aphids, of the family Eriosomatinae, secrete a coating that looks like cotton or wool onto your plant. Once you notice you have a problem with woolly aphids, time is of the essence; the insects can destroy your plants if not watched closely and taken care of quickly. Treatments to get rid of the woolly aphid range from poisons to home remedies. It is critical to be vigilant and repeat treatments three to four times in one week to ensure that all aphids and eggs have been removed.

Things You'll Need

  • Rubbing alcohol
  • Spray bottle
  • Hand soap
  • Peppermint organic soap
  • Garlic juice/Tabasco sauce/jalapeno juices
  • Water
  • Dimethoate

Rubbing Alcohol

  • Pour rubbing alcohol into a spray bottle.

  • Spray plant and surrounding soil heavily. This will dehydrate the bugs.

  • Repeat this process until all aphids are gone.

Dish Soap

  • Mix 1 tablespoon of dish soap with a spray bottle full of warm water.

  • Spray the entire plant and surrounding soil. This will break down the waxy coating of the aphid.

  • Treat the plant this way three to four times over a week's span.

Household Foods


  • Spray Dimethoate onto all portions of the plant and surrounding area. Dimethoate is a chemical available at garden centers.

  • Moisten all areas are thoroughly.

  • Repeat steps four times in a week. It will take longer to kill all aphids due to the waxy coating on them.

Tips & Warnings

  • You can also combine the tablespoon dish soap with the tablespoon of rubbing alcohol. This will help destroy the aphids faster, as the soap will break down the waxy coating while the alcohol will dehydrate the aphids.
  • You can add peppermint extract to your soap mixture, or use an organic peppermint soap such as Dr. Bonner's. The smell of peppermint will deter not only the aphids but other insects and pests, as well as rodents.
  • If the aphids have infested the root of your plant, Dimethoate can be mixed with water. Soak the soil repeatedly over the next week until the aphids are gone.
  • Always do a spot test on your plants first to make sure that the treatment you will be using is safe for the type of plant you are using it on.
