Gardening can be both rewarding and frustrating. On the one hand, it is deeply satisfying to create something from nothing, growing a bounty of vegetables and flowers from a patch of soil. On the other hand, garden pests can wreak havoc in a short amount of time, destroying all your hard work. Here is an overview of some of the most notorious garden pests and how to squash them.

Common Garden Pests


Aphids are small insects, usually ranging in color from green to yellow to brown. They feed on the sap of plants, and their secretions can cause yellowing and wilting of the leaves. Aphids reproduce rapidly and can quickly take over a garden. To control them, use organic sprays of pyrethrin, insecticidal soap, or neem oil. You can also use beneficial predators such as ladybugs, lacewings, or hoverflies.


Caterpillars are the larvae of butterflies and moths, and can vary drastically in size, shape, and color. They feed on the foliage of plants, creating holes and damaging leaves. The best way to prevent caterpillars from taking hold of your garden is to keep the area clean, removing any debris or weeds that may provide shelter. If the population grows too large, use a Bacillus thuringiensis (BT) spray to keep them in check.

Slugs are small, slimy creatures that love to munch on garden plants. They can be particularly damaging to seedlings and newly planted flowers. To combat slugs, sprinkle diatomaceous earth around your plants, which will act as a barrier and reduce the slug population. You can also use beer traps to lure the slugs away from the plants, or hand-pick them off the foliage at night.


Snails are similar to slugs, but they have hard, protective shells on their backs. They can be found hiding in dark and damp places, munching on young foliage and flowers. To control them, keep the garden clean by removing any piles of debris, as these can provide a hiding place for snails. Sprinkle diatomaceous earth and salt around the plants to make the soil inhospitable to snails.


Cutworms are the larvae of night-flying moths. They feed on young plants, cutting through seedling and plants with their sharp, firm jaws. Their damage can be substantial, with plants and seedlings completely decimated. The best way to prevent them is to use a sticky material such as molasses or corn syrup around the base of the plants; this will act as a barrier to keep the cutworms away.


Whiteflies are tiny, powdery white insects that feed on the sap and juices from plants. They reproduce rapidly, and in large numbers can quickly take over a garden and cause severe damage. To control them, introduce beneficial predatory insects such as ladybugs, or use an organic spray to kill off the whiteflies.

Fungus Gnats

Fungus gnats are small, dark insects that feed on the roots and leaves of plants. They reproduce in moist and damp soil and can be identified by the white larvae they create. To prevent them, keep the soil dry and aerated; mulch can also help. If the population is large, use a neem oil spray to knock them back.


Thrips are small, slender, insectlike creatures that feed on the leaves of plants. They explain their territory by leaving a distinctive, bronze-colored trail of excreted waste. To control them, use sticky materials such as molasses to trap them, or use a natural spray of neem oil or insecticidal soap.


Mealybugs are small, soft-bodied creatures covered with white, powdery wax. They feed on the juices of plants, sucking them dry and leaving behind a sticky residue. To control them, use insecticidal soaps or spray the plants with rubbing alcohol. You can also introduce beneficial predators such as lacewings or ladybugs.
