How to Control Cucumber Beetles Naturally

Cucumber beetles are tiny insects that are mostly found around cucumber plants, but also love feeding on melons, squash, potatoes and tomatoes. These yellowish green tiny insects not only destroy the crop by eating the fruit or vegetable, but also spread a serious disease called “bacterial wilt”. Besides cucumber plants, several other plants in the garden also get affected by this disease, leaving the gardener with no other choice, but to get the affected plants out of the garden. Since cucumber beetles mostly attack edible plants, you cannot spray harsh chemicals to get rid of them. However, there are several household items that you can use to deter these insects and keep them from eating your plants and fruit.

– 1 oz. hydrated lime
– 1 gallon water
