Identifying ground-nesting bees and yellowjackets can be simplified with a one-minute observation of their nesting behavior. According to the Oregon State Extension, if there is a single entrance with repeated insect activity, it is likely a yellowjacket nest. In contrast, ground-nesting bees typically have multiple smaller burrows scattered across an area. Yellowjackets, which are social insects, often create noticeable mounds of dirt near their nests, while solitary ground-nesting bees do not exhibit such behavior. Their physical characteristics also differ; yellowjackets are slender and shiny, while bees are fuzzy. Observing these traits together can provide a clearer picture of what type of insect is present. However, caution is advised, as yellowjackets can be defensive. The one-minute check is a useful tool, but it should be supplemented with additional observations for accurate identification.
