We have a potted plant that resides outside in the spring, summer and fall, and comes inside in the winter. It brings in with it tiny ants that take a tour of the house every time we water the plant. The pot is quite large. If we add insecticide to the watering can will it harm the plant?

It is not recommended to add insecticide to the water as it can harm the plant and it is not labeled for this use. Take the plant outside if possible. Try flushing the plant thoroughly with water to dislodge the ants and you may need to do this several times. After the plant is put in its location indoors put some ant traps on the surface of the soil to trap any ants that may be left in the soil. There are many types of ant traps. Try prefilled ant baits that contain a sweetener and borax as the active ingredients. As an added precaution you can place several ants traps at the base of the plant as well. As a last resort you can repot the plant.
