Introduction

Roly poly bugs, also known as pillbugs, are common garden pests that feed on decomposing plant matter. Unfortunately, they also have a taste for young and tender tomato plants. While they may not cause significant damage to mature plants, they can devastate seedlings and young plants in a short amount of time. Fortunately, there are several strategies you can use to protect your tomato plants from roly poly bug infestations.

Cultural Control

One effective way to control roly poly bugs is through cultural techniques. First and foremost, it's important to maintain a clean and healthy garden environment. This means removing any debris or rotting organic matter that may be attracting roly poly bugs. You should also avoid over-watering your tomato plants, as damp soil can serve as a haven for these pests. Additionally, companion planting with plants that repel roly poly bugs, such as garlic or chives, can be a useful way to deter them from entering your tomato patch.

Physical Control

Another option for controlling roly poly bugs is through physical methods. This can include handpicking them off your tomato plants and disposing of them in a bucket of soapy water or crushed eggshells. You may also consider placing a ring of diatomaceous earth around your tomato plants, which will cut into the soft exoskeletons of roly poly bugs and cause them to dry out and die. Alternatively, you can form a barrier around your tomato plants using copper tape, which will act as a repellant by creating a mild electrical charge as the bugs come into contact with it.

Biological Control

The use of biological control methods can also be effective in managing roly poly bug populations. One choice is to introduce beneficial predators, such as ground beetles or centipedes, to your garden. These insects will feed on roly poly bugs and other pests, providing a natural and organic approach to pest control. You can also consider applying nematodes, naturally occurring microscopic worms, which will infect and kill roly poly bugs in the soil.

Chemical Control

While chemical insecticides can be effective in killing roly poly bugs, we recommend using them as a last resort since they can be harmful to beneficial insects and the environment. If you decide to use an insecticide, choose a product that specifically targets roly poly bugs and follow the instructions carefully. Remember to wear protective gear and keep children and pets away from the treated area. It is important to note that overuse of chemicals can lead to resistance in pests and harm biodiversity, ultimately exposing your tomato plants to greater levels of pest infestations.

Conclusion

Roly poly bugs can quickly become a major problem for tomato plants, particularly those that are young and vulnerable. Fortunately, by practicing good cultural habits and using physical, biological and chemical controls if needed, you can protect your tomato plants from roly poly bug damage.
