Natural Predators
Natural predators are another way to keep aphid, and other insect pest, populations in check and reduce the need for chemical controls. Several predatory and parasitoid insects as well as spiders feed on aphids. Ladybugs, ladybug larvae, soldier beetles, hover flies, predaceous midges, big-eyed bugs, lacewings, parasitic wasps, hornets, yellow jackets, spiders, and assassin bugs all feed on aphids. Predators do not show up in the garden until there is a food source present, so there will be a gap between the appearance of aphids and the appearance of predators.
Controlling Aphids
If spraying your plants with water isn't working or your aphid problem exploded faster than your predator population could handle, there are many different chemical control options for every areas of your yard. On your roses and ornamentals, use Ortho® Insect Killer Rose & Flower Ready-To-Use. For aphids in multiple areas of your garden and landscapes, use Ortho® Insect, Mite & Disease 3-in-1 Ready-To-Use for small jobs and Ortho® Tree & Shrub Fruit Tree Spray for large jobs. Always check the label to make sure your plant is listed before applying, and always follow the directions for use.
