Identifying Garden Pests

Pests in your vegetable garden can cause significant damage if left unchecked. It’s important to catch pest infestations early before they can cause significant damage to your vegetable garden.

Before you can effectively prevent pests in your vegetable garden, you need to know what you’re dealing with. Here are some common garden pests to look out for:

Aphids:

These small, pear-shaped insects can be found on the undersides of leaves and stems. They suck the sap out of plants, causing stunted growth and distorted leaves.

Signs: Stunted growth, distorted leaves, and a sticky residue on leaves are all signs of an aphid infestation.
Damage: Aphids can cause stunted growth and distorted leaves. They can also spread viruses between plants.

Caterpillars:

Caterpillars are the larval stage of moths and butterflies. They can be found chewing holes in leaves and can quickly defoliate a plant if left unchecked.

Signs: Holes in leaves, missing foliage, and droppings on leaves are signs of a caterpillar infestation.
Damage: Caterpillars can quickly defoliate a plant if left unchecked, leading to reduced yields or even plant death.
