Colorado potato beetle

Asked June 3, 2016, 12:44 PM EDT

In your recommendations for Colorado potato beetle control it is mentioned that floating row covers will help. Because they arrive from the soil below doesn’t that trap them under the covers with the plant? How do the row covers help? Do you have any other tricks? These guys are voracious! Thanks

It is true that row covers can trap the beetles. Look at our pest profile on this beetle.
You will have to be vigilant about checking for eggs and larvae before you put the row covers on. They tend to hibernate in waste areas and weeds. Control your weeds. Rotate your potatoes to different parts of the garden each year. Slow-moving adults do not disperse far. Spring and fall tilling reduces populations of overwintering adults.
