How do you get rid of striped cucumber beetles??

Question

I tried Rotonone. They seem to eat that stuff for breakfast, lunch, and dinner and don't die.

Answer 1

Use a portable vacuum to get the adults in the early evening. Try placing cuttings Tansy, Rue, & Catnip as a mulch in-between rows in the garden.
Spread any type of onion skins on the soil around the planted areas. Plant white varieties of radishes with your cucumber plants to repel the beetles.

Prevent infestation by cleaning up all plant debris. Dust Diatemous Earth around the base of plants to kill larvae emerging to eat and also create a barrier to egg laying. Dust fine, powdery flour or lime to suffocate the pests.

Use wood ashes between rows. Moisten it so it won't blow away and don't let it get on the plants, because it can be toxic to them. It dehydrates soft-bodied insects. It's a good akaline fertilizer containing potassium, calcium & phosphorus.

A deep mulch of straw can deter cucumber beetles from laying eggs in the ground near plant stems and may hinder feeding by larvae migrating to fruits, but does not protect the leaves against attack from adult insects. Injury to fruit by tunneling of larvae is dependent on very moist soil as fruits ripen. Limiting irrigation at this time can minimize damage.

Use a spray of hot peppers, water and garlic.

Trellising plants can make leaves less accessible to insect larvae and may decrease egg-laying.
Floating row covers are an effective control method during the early season of plant growth, forming a barrier between insects and plants. Row covers need to be removed to allow for bee pollination.

To fool cuke beetles: flatten a square of aluminum foil around the base of plants to bounce light on the undersides of leaves. This also helps the plants in giving them more light.

Apply beneficial nematodes to kill the adults in mulch, seed furrows and around plant roots. Encourage other predators: Bats, Lacewings and ladybugs.
Neem Oil: Neem oil, can be used as a soil drench to treat eggs and larvae to help repell beetles.
Cultivate in the fall to expose the eggs.

Good luck! Hope this helps.

Answer 3

insecticide called sevin it is a systemic which is a stomach poison once it is in the plant. apply sevin, the plants absorb the chemical thereby making the plant poisonous to the beetle when it is consumed.
