Want to keep your houseplants healthy?
Those that summer outdoors will require extra attention, but even those that stay inside can harbor insects.
Wash the pots and foliage with mild, soapy water.
Use a mild soap such as Ivory, not a detergent.
Then turn the pot over and dunk the plant in mild, soapy water.
Rinse in clear, lukewarm water.
Repotting in clean soil often will physically remove insects that otherwise would travel indoors with your plants.
If you dont wish to repot them, let the soil dry out completely before watering.
Humidity loving insects will either die or find a new home.
Remove discolored or dying leaves and stems, and youll remove a potential hiding place for insects.

Identifying Specific Pests
#1.
Aphids
Wilting plant tips are a sign of aphids.
Aphids multiply rapidly, and for much of the year bear live young without mating.
#2.
Mealybugs
Look for bud drop and foliage damage.
Mealybugs have soft, oval bodies and produce cottony fluffs over themselves.
Look for them on the undersides of leaves in leaf axils.

#3.
Mites
Look for fine webs and mottling on plant leaves.
Mites themselves are extremely tiny, the size of dust specks.
They also spread easily, traveling on hands and clothing or in puffs of air.
#4.
Scale
These light-colored insects look just like their name implies.
The light-colored scales sometimes have hard-shelled bodies.
On the plant, they often look like a growth or fungus.
#5.
Whiteflies
When disturbed, they fly around the plant like swirling bits of dust.
Whiteflies easily develop resistance to insecticides.
Ants are attracted to the sweet honeydew secreted by aphids, mealy bugs, scales, and whiteflies.
Ants nesting in the pot must be repeatedly flooded.
This works best when you provide a drier home nearby.
Place a bucket of compost next to the infested pot.
Place a stick bridge between the two containers.
Once the ants have all left the flooded plant, you’re free to dump the compost outdoors.
Insect Pest Controls
The simplest and safest method of controlling insects is a soap and water bath.
Aphids, mealy bugs, mites, and young scales all can be washed away.
Those that remain will be more susceptible to disease outbreaks because of the higher humidity in their immediate environment.
Dip the cotton swab in alcohol to rub away aphids or mealy bugs.
A bath in weak alcohol and water solution will kill large infestations without harming most plants.
The spray is safe for most plants.
Chemical insecticides should be used as a last resort on indoor plants.
Choose a spray formulated for indoor use and apply according to label directions.
Garden insecticides such as Sevin or malathion may be used.
However, use half-strength or weaker solutions.
Take the plant outdoors to spray and allow it to dry before bringing it back in.
Never spray indoors where ventilation is inadequate.
Be sure the wind carries the spray away from you, not onto you.
Wear protective clothing and gloves.
Mix only as much insecticide as you need, and dispose of any leftovers according to package directions.
