Many states, including Iowa, received a record amount of precipitation in 2019. In fact, the past two growing seasons have been especially wet. Consequently, this has created a number of issues for farmers, including reports of millipedes damaging crops under no-till production in Iowa, which is likely due to a combination of wet conditions and high residue. People that experience millipedes under these conditions frequently ask if insecticides or seed treatments will provide control of these pests. Although millipedes are not insects, they commonly fall under the realm of entomology, alongside many other animals (spiders, centipedes, mites, etc.). We will provide a brief discussion of non-insect crop pests, particularly millipedes and isopods, and potential management options.
