The Q&A Archives: Deterring Flea Beetles

Question: What is a good organic way to ward off flea beetles? If the plants become big enough do the bugs become a nuisance as opposed to being an actual threat? It seems that once the cucumber or squash plants become a certain size, the flea beetles no longer seem interested in eating them. Is this true? Thank you very much for your help and advice.

Answer: Yes, once your plants are large enough, flea beetles no longer are interested in them. When the plants are young, cover the seedlings with floating row covers to protect the plants and check daily unde the covers for any beetles that snuck in. Spray them with pyrethrum insecticide to keep them at bay. Pyrethrum is an organic, botanical spray with low toxicity.
