Garden Tip: Asparagus Beetle Trap

December 9, 2022

By Blair Rollin, Scotland, Connecticut

I wanted to let people know about an asparagus beetle trap I came up with. 2022 is the second year I’ve used these, and they have pretty much ended my asparagus beetle problems. I used to spend countless hours catching and killing asparagus beetles by hand. (I got quite good at it as I am smarter than an asparagus beetle.) Still, I had a lot of beetles and larva. This year, probably not 10 minutes spent killing beetles by hand. As you can see from the photo, these super simple and cheap traps are highly effective.

Cut 1-foot pieces of ½- to ¾-inch dowel. Sand, carve or otherwise shape one end to resemble an asparagus spear. Paint green. (I used Tractor Supply’s oil-based tractor and implement enamel, John Deere green.) Coat the business end with Tanglefoot and stick the other end in the ground. I put one trap every 5 feet of bed. Put out in early spring at first sighting of beetles.
