Planting Tagetes Or Marigolds With Brussels Sprouts

I have found that planting tagetes or marigolds with Brussels sprouts is an effective way to keep bugs away. The strong scent of the flowers repels pests such as aphids and whiteflies. Additionally, the flowers attract beneficial insects like ladybugs and lacewings that feed on these pests.

Applying Insecticides

Insecticides can be used to control pests on Brussels sprouts. However, it is important to use them sparingly and only when necessary. I recommend using organic insecticides such as neem oil or pyrethrin, as they are less harmful to the environment.

Using Aluminum Foil

Wrapping the base of the Brussels sprout plant with aluminum foil can prevent cutworms from damaging the plant. Cut a strip of foil and wrap it around the base of the plant, making sure it is tight enough to prevent the worm from crawling underneath.

Using Parasitic Wasps

Parasitic wasps are natural predators of many pests that attack Brussels sprouts. These tiny insects lay their eggs inside the pests, which then die as the wasp larvae hatch. You can purchase parasitic wasps from a garden center or online.

Using Garden Fabric Or Floating Row Covers

Garden fabric or floating row covers can be used to protect Brussels sprouts from pests such as cabbage worms and flea beetles. These covers create a physical barrier that prevents the pests from reaching the plants.

Using Bacillus Thuringiensis

Bacillus thuringiensis (Bt) is a natural bacteria that is toxic to many pests that attack Brussels sprouts. It can be sprayed on the plants to control pests such as caterpillars and loopers.

Using Collars To Protect Young Plants From Cutworms

Cutworms are a common pest that can damage young Brussels sprout plants. To protect the plants, I recommend making collars out of cardboard or plastic cups. Cut the collar to fit around the base of the plant and push it into the soil.

Preventing Snails And Slugs From Eating Leaves

Snails and slugs can be controlled by placing a barrier of diatomaceous earth or crushed eggshells around the base of the plant. These materials are sharp and will deter the pests from crawling over them.

Using Organic Chemicals

Organic chemicals such as spinosad and pyrethrin can be used to control pests on Brussels sprouts. However, it is important to use them sparingly and only when necessary. These chemicals can harm beneficial insects as well as pests.


In conclusion, keeping bugs off of Brussels sprouts is essential to ensure a healthy and bountiful harvest. During my research, I have found that prevention is key, and there are several effective methods to keep bugs at bay.

First and foremost, it is important to inspect your plants regularly and remove any diseased or infested leaves. Additionally, planting companion plants such as marigolds or herbs like basil can help deter pests.

Using natural insecticides such as neem oil or insecticidal soap can also be effective, but it is important to follow the instructions carefully and avoid using harmful chemicals.

Finally, covering your plants with row covers or netting can provide a physical barrier against pests and protect your Brussels sprouts from damage.

By implementing these strategies, you can keep your Brussels sprouts healthy and pest-free, ensuring a successful and delicious harvest.
