Spray the outside plants with Neem (orange) oil. Spray your house plants with Safer soap or with the Neem oil. Safer soap is not residual, and will have to be sprayed about every ten days until you get control. Neem oil will break down in a couple of weeks in the sun, and may have to be reapplied a time or two. Be sure to spray the soil under the plants too, as that's where they reproduce.
