Radishes are not only delicious but also an excellent natural deterrent for cucumber beetles. These pests dislike the smell of radishes and will avoid them at all costs. Planting radishes around your cucumbers or other cucurbits will help keep these beetles at bay. Additionally, radishes also act as a trap crop, attracting the beetles away from your main crop.

3. Marigolds

Marigolds are another popular companion plant that can help repel cucumber beetles. They contain a compound called thiophene, which is known to repel pests. In addition to their pest-repelling properties, marigolds also attract beneficial insects like ladybugs and lacewings.

4. Catnip

Catnip is a natural repellent for many pests, including cucumber beetles. Planting catnip around your cucumbers will help keep these pests away. Additionally, catnip is also an excellent attractant for beneficial insects like bees and butterflies.

5. Tansy

Tansy is a flowering herb that contains a compound called thujone, which is toxic to many insect pests, including cucumber beetles. Planting tansy around your cucumbers or interplanting them between rows can help keep these pests at bay.
