Houseplants often acquire bugs when they are left outside or a new plant that is a carrier is introduced to the home. Aphids, scales, mealybugs, spider mites and whiteflies all pose a problem to houseplants. Always look at new plants closely before bringing them into the home to determine if they harbor any pests. If possible, quarantine a new houseplant away from the general houseplant population for up to three weeks to determine if it has any pests. If a houseplant suffers from a pest infestation, prompt treatment is necessary to reduce the risk of all the houseplants contracting the insects. Does this Spark an idea?
