The most common tomato pest, but also one of the most destructive, is the aphid. These critters have soft, pear-shaped bodies and are typically white, black, brown or even pink. Aphids infest a wide range of plants, including relatives of the tomato, potatoes and eggplants.

They settle on new shoots and on the underside of young leaves. Aphids are sap-sucking insects and leave behind a sticky substance that attracts various other nuisance insects. Although they are one of the most destructive insects, especially in more temperate climates, a small infestation is not a major problem. However, if left untreated, they will reduce the yield of your plants and can even cause the plants to die.

Fortunately, aphids are easy to get rid of. Due to their small size, they are easy to wipe or pick off with your fingers and kill. Also, you can spray them off with a spray bottle. The water spray will blast them off the tomato plant and leave no damage. A natural soapy water (or nettle broth) applied with a spray bottle is another common way to smother the bugs. You can also use an organic pesticide based on neem oil or canola oil to control tomato pests.

In extreme cases, it may be necessary to prune or cut off the infested leaves or other plant parts. To prevent aphid infestations, for example, plant nasturtiums to attract aphids away from your tomatoes and choose plants that attract predatory insects such as ladybugs and hoverflies.

Whiteflies are tiny insects closely related to aphids. They are found in almost all regions and usually feed on the underside of plant leaves. Whiteflies are commonly found on tomatoes, especially when grown indoors or in greenhouses. Both nymphs and adults damage plants by sucking sap, resulting in growth disturbances, leaf yellowing and yield loss.

Thrips are tiny insects that are quite difficult to see, so an infestation can easily get out of control before you notice it. Telltale signs of a thrips infestation include dry or brown spotted leaves, fallen leaves and blotchy flowers. While it’s unlikely that thrips themselves will kill your plants, they could transmit diseases that do.

Earthworms are capable of killing a tomato plant overnight. These gray or brown caterpillars with black or yellow spots are about two inches long and extremely damaging. These stealthy caterpillars work at night, leaving large holes in your tomatoes. But the fruit is not the only victim. Seedlings are usually the most susceptible, but the caterpillars also attack the stems, eventually causing the plant to fall over. During the day, they hide under the soil or under plant debris.
