  • How do I stop roly poly bugs from eating my plants?

    Created by Britta Hubbard on

    I have a 10×10 greenhouse that is currently housing 100s of roly-poly bugs. They are eating my plants — everything! I have planted seeds a number of times, but these crazy Crustaceans are eating the sprouts before they even surface, and if anything is lucky enough to surface, the creatures are eating it down like a might pack of lumberjacks. HELP!!! I bought a Diatomaceous earth mixture, but as far as I can tell, it did not help much. I scattered it all about the dirt. Some died, but not many. I saw lots of “natural” insecticides, but these are Crustaceans – is there anything that will help me with this highly problematic infestation?

    Hello Britta!

    Diatomaceous earth is abrasive to crawling insects, like roly-polies, and can be used as a barrier to protect plants. However, it is important to reapply DE after watering, it becomes less effective when wet. Lightly coat the areas where these pests are found or may hide. Repeat treatment as necessary.

    Another product you can try is Monterey Ant Control. It’s proven to be effective against pests such as sow bugs and is a safe, organic solution to problems that arise from them. Simply scatter the bait granules on the soil around or near the plants to be protected. In greenhouses, scatter the bait in the pots of plants being damaged or around pots on greenhouse benches.

    Below is a link to our page on sow bugs which includes information from life cycle to identification to control with suggested products such as the ones mentioned above.

    Happy gardening!
