How to identify squash bee nests
Please help us collect these data by submitting your information below
Squash bees are active from July to September and tend to make their nests in patches of exposed ground on the edges of cucurbit fields, although they are sometimes found directly underneath the plants themselves. Even though each female makes her own nest, females tend to nest near each other in an aggregation. The nests are easiest to find in the early morning when the bees are active. You’ll often hear them before you see them! Here are several pictures of nesting aggregations and sites that will help you to locate and identify the nests.
