Coyote poo poo?
We appear to have acquired a nice mealybug infestation. The stems and leaves of some of our shrubs and plants are affected. Looks like white cottony fluffy stuff- what do we use to get rid of them?
Actually, it sounds like you have spittle bugs, they have the white foamy appearance you describe. They love this dry weather and attack everything. I wash them off with the spray attachment of my waterhose, then douse them again, just when they think they've escaped by landing on the surface of my screened porch. A really good daily rinsing of the affected plants should save them until we get the much needed rain to take care of them for you.
