Get rid of spider mites without pesticide

Below is an article I found on a home made recipe for getting rid of spider mites from your bonsai trees. We have not had a chance to try this ourselves, but we have found this is a popular method for treating spider mites semi-naturally.

Natural Spider Mite Miticide

By Carl L. Rosner


  • Water
  • Dish Detergent
  • Rubbing Alcohol


Fill a gallon jug with water and add one (1) or two (2) tablespoons of dishwashing detergent and one (1) tablespoon of vegetable oil (or Neem oil). Shake up the gallon jug to mix the ingredients.

Fill this solution from the gallon bottle into a spray bottle and just before using add 1 to 2 two caps full (from the rubbing alcohol bottle) of rubbing alcohol and spray immediately. If you do not use the full bottle of spray, I suggest the next time you are going to use the soap/alcohol solution add the same amount of rubbing alcohol again, since the alcohol will evaporate. I store this soap/oil solution in the gallon jug for months on end. It does not seem to go bad.

Spray on plants covering all leaf and stem surfaces. You may have to spray from three to four times with intervals of three days. I have eliminated almost any kind of pest that has attacked my trees, including scale.

I do not wash off the spray and have seen no adverse reaction to the trees from this mixture.
