Aphids are one of the most common insect pests found on garden plants, from vegetables to roses. Each aphid species typically targets members of a single plant family, but multiple species can be at work in one garden. Aphids can reproduce without mating, so their numbers can soar in just a few days. They also feed in very dense masses, making them one of the most destructive of all plant-eating insects.

Aphid Identification: Aphids are soft-bodied, teardrop-shaped pests that come in several colors. Depending on the species, they may be green, yellow-orange, black or reddish pink. They often have a wooly or waxy appearance, and adults typically do not have wings. Unlike similar-looking insects, aphids move slowly when disturbed.

Signs/Damage of Aphids: Aphids damage plants by piercing them with their mouthparts and sucking out the plant juices. They often target tender, young growth, such as soft stems and new leaves or buds. Plants are left wrinkled, curled and puckered, with stunted growth. Another sign of aphid problems is black sooty mold that forms on the sweet “honeydew" aphids excrete as they feed. Aphids can also transmit viruses between plants.

How to Control Aphids: Aphids multiply quickly, especially during times of rapid plant growth, so treat at the first sign of problems. Treat all plants surfaces, upper and lower, thoroughly — and check for aphids hiding in curled, distorted leaves. GardenTech® brand offers several highly effective options for treating problem aphids and protecting plants for up to three months

  • Sevin® Insect Killer Ready to Use simplifies target spot treatments of aphid masses as well as total plants. The adjustable nozzle lets you control the width of your spray, so you can avoid open blooms that draw beneficial pollinators.
  • Sevin® Insect Killer Concentrate provides an easy, economical alternative for treating larger areas with a pump-style sprayer.
  • Sevin® Insect Killer Ready to Spray connects to a standard garden hose to simplify treating shrubs, foundation plantings and other areas quickly and thoroughly.

Tip: Some types of ants feed on aphid honeydew. To keep the supply coming, these ants protect aphids from beneficial predator insects that normally help keep them in check. Treat problem ants along with aphids to nip both problems in the bud.

Always read product labels and follow the instructions carefully.
