Protect your crops! Cucumber beetles are attracted wherever squash, cucumbers, watermelon, pumpkins and other cucurbits are grown. Beetles can kill or stunt seedlings, and on older plants, damage stems and fruit. This beetle is also known for transmitting bacterial wilt and other viruses. Beetle larva feed on the plants roots reducing yields. Place lure on sticky trap and place one per 2000 square ft. for monitoring or every 400 square ft. for trapping. Lure lasts 3-4 weeks.
