Of all the pests I
receive in my garden, the one I see each year – without fail – is the cucumber
beetle. To keep my cucumber plants healthy and productive it is important for
me to know when the beetles arrive, what they do to my garden, and how to
remove them.
How do you know if your garden has cucumber beetles?

Here in the South,
these beetles can come in many sizes,
colors and patterns. The dominant color is black with white stripes
followed by a green variety that possesses black spots. In the past I have seen
some that are nearly neon, though more rare cucumber beetles can sometimes be
hard to catch – let alone to take a picture of.
To find the beetles, start by looking at your flowers – and more specifically in your flowers. If there are cucumber beetles in there you will see them coming out and flying away.

Cucumber beetles
destroy both male and female cucumber flowers. In addition, if left in the
garden they act as vectors for disease and can cause otherwise healthy plants to
become diseased. Though most of the references I have read have only noted that
cucumber beetles cause bacteria wilt, I have often suspected cucumber beetles
of spreading some form of cucumber mosaic as well.

How does one get rid of
these pests?

Because cucumber
beetles tend to be very skiddish around people (with good reason) it helps to
eradicate them early in the morning. Around dawn, when many friends I know are
still feeling sluggish and tired – so are the cucumber beetles. They are a lot
slower and, when coaxed out of a cucumber flower, tend to drop on the ground
rather than fly away. Simply place the palm of your hand below the cucumber
beetle and he (or she) will simply drop down into your palm where you can
determine its fate.

Though cucumber
beetles are annoying, when compared with other garden pests (such as the
notorious squash-vine borer) they are extremely manageable. By keeping my garden free of cucumber beetles
I am not only helping myself but all the gardeners around me.
