Wouldn't you know it.
This garden pest, the asparagus beetle eats asparagus.
Not in your refrigerator...but in the fields where your store bought asparagus grows.
The asparagus beetle comes in two flavors...on the left is the Spotted Asparagus Beetle and on the right is the Common Asparagus Beetle.
The Asparagus Beetles are both most active in the afternoon and both Asparagus Beetles can do enough damage to your crop that the asparagus will be unmarketable.The spotted is most destructive of the two asparagus beetles.
How to get rid of the Asparagus Beetle:
ORGANIC CONTROL:
- Plant tomato plants nearby as they repel the asparagus beetle.
- Hand picking and squashing the larvae and adult beetles works.
- Brush the larvae off the plant onto the ground were they will die as they are unable to remount the plan
- Hope that some lady bugs find your asparagus garden as they know how to kill Asparagus Beetles.
BIOLOGICAL CONTROL: Purchase some parasitic wasps on the internet. Release them and they will paralyze the larvae, reducing your population of Asparagus Beetles.
CHEMICAL CONTROL: Insecticides if used, must be applied early in the morning or late in the evening to limit the numbers of beneficial insects that would be killed as a result of the spraying.
