How do I treat lilac bushes that have insects?

Answer by  sanityrose (2664)

You should treat insects on a lilac bush with very mild insecticides or a simple home remedy. The best remedy is soap and water. Add one teaspoon of mild dish soap to each 2 cups of water and spray the affected areas of the lilac. You should continue to spray twice a day until the insects are gone.

In most cases, insects in lilac bushes can be treated with a spray bottle filled with soapy water. In more severe cases, you may need to purchase some type of insecticide.
