Common Alabama Garden Pests

If you grow vegetables in Alabama, something else will eventually try to eat them.

That’s normal.

The goal isn’t to create an insect-free garden. The goal is to recognize which visitors are causing meaningful damage and respond without destroying the beneficial organisms helping you.

First Rule: Identify Before You Treat

Never spray an insect simply because it is sitting on a plant.

Many garden insects are:

Take a photo and identify the pest first.

Aphids

Aphids are small, soft-bodied insects often clustered on new growth or underneath leaves.

Signs

Management

A strong stream of water can remove light infestations. Beneficial insects often provide control when broad-spectrum insecticides are avoided.

Squash Bugs

Squash bugs attack squash, pumpkins, and related plants.

Signs

Inspect leaf undersides regularly and remove egg masses early.

Squash Vine Borers

A healthy squash plant can suddenly collapse when larvae tunnel into stems.

Signs

Early detection is critical.

Tomato Hornworms

These large green caterpillars can strip foliage quickly.

Despite their size, they are remarkably good at hiding.

Hand-picking is often practical in a home garden.

If you find a hornworm covered with small white parasitoid cocoons, consider leaving it in place so the beneficial wasps can complete their life cycle.

Cucumber Beetles

These small beetles feed on cucumbers, squash, melons, and related crops.

Young plants can be especially vulnerable.

Row cover can protect seedlings before flowering, but it must be removed or managed once pollinators need access.

Flea Beetles

Flea beetles make many tiny holes that can give leaves a shot-peppered appearance.

Young eggplant, brassicas, and other seedlings can be heavily damaged.

Healthy mature plants usually tolerate more injury than tiny transplants.

Cabbage Worms and Loopers

These caterpillars feed on:

Check leaf undersides and plant centers.

Small populations can often be hand-picked.

Stink Bugs and Leaf-Footed Bugs

These sap-feeding insects can damage tomatoes, peppers, and developing fruit.

They often become more noticeable later in summer.

Japanese Beetles

Japanese beetles can skeletonize foliage and flowers.

They feed on many plants and often appear in groups.

In small gardens, knocking beetles into soapy water early in the morning can reduce populations.

Slugs and Snails

These pests prefer moist, protected conditions and often feed at night.

Look for:

Reduce hiding places and avoid keeping the surface constantly wet.

Use Integrated Pest Management

A simple IPM approach:

  1. Identify the pest.
  2. Decide whether damage actually requires action.
  3. Use physical or cultural controls first.
  4. Encourage beneficial insects.
  5. Use the least disruptive effective treatment when intervention is necessary.
  6. Follow pesticide labels exactly.

Grow a Garden, Not a Sterile Exhibit

A few holes in a leaf are not an emergency.

Healthy gardens contain insects.

Your job is to keep the system balanced enough that pests don’t take over.
