kills all insects. Pests; predators and

sprays also control aphids.or wash them off with a
little detergent and water
Cultural or Physical control "digital" control
"squish "em" and weed control, removing alternative
hosts or even primary hosts
Biological Control; parasitic wasps (usually of the
Hymenopterous Families Aphidiidae, Aphelinidae, or
Braconidae)
Aphid predators. Ladybird beetles and larvae
(Coleoptera: Coccinellidae) the larvae of lacewings-
Micromus tasmaniae (Neuroptera: Hemerobiidae).
hoverflies larvae (Diptera: Syrphidae)
An aphid fungus, Entomophthora aphidis attacks some
species, notably the cabbage aphid.
