Aphids damage plants by sucking
the sap from the leaves, twigs, stems or roots. They sometimes transmit plant
diseases in the process. Leaves attacked by aphids have spotty yellow
discolorations, usually on the undersides; the leaves may later dry out and wilt
or curl. Some species of aphids form galls - swellings of plant tissues that are
globular or spindle-shaped. The galls, which often turn brown, contain many
aphids in all stages of development.
Do you see a clear, shiny sap on the top of the lower leaves on your plants?
Many aphid species produce large amounts of honeydew, a sweet and sticky sap.
The honeydew will accumulate on anything found under infested trees or plants
(such as your car!). Because of its sweetness, the honeydew will attract other
pests such as ants, flies and wasps. Eliminating the aphids can often help aid
the management of problem ants.

Control
We suggest Talstar Flowable or
Suspend SC. These odorless concentrates are mixed with
water and applied with a pump sprayer. These are great products to use when you
have large areas to treat and need something which works well so you don't have
to constantly retreat with something like an insecticidal soap. Use these
products outside of the home on just about any plant or tree as well as around
the home for general pest control.
