How to Get Rid of Striped Cucumber Beetle?

As is always the case, it is much more difficult to stop an infestation that has started than to prevent it. In this particular case, the reason is that when the cucumber leaf-eating insect starts feeding, it releases pheromones containing volatiles, and more striped leaf beetles arrive to feast.

Of course, you shouldn’t give in, but you should always try to get rid of them or at least reduce their population. Inspect your plants regularly and crush any beetles you find there by hand or throw them in a container of soapy water. You can also make your own sticky traps using glue-coated yellow cups that look like the flowers of zucchini and cucumbers and will attract intruders, but won’t let them go.

Finally, you can make your own homemade organic insecticide using neem oil or a garlic infusion, for example. Pyrethrum may otherwise be effective, but it must come into contact with the beetles to affect them, as it does not leave a residue on the leaves. True, it is the striped leaf beetle that eats cucumber leaves, but this insect has its own natural predators. So invite ground beetles into the garden, and don’t use pyrethrum if you notice pollinators and other beneficial insects working their magic in the yard.
