What are Squash Vine Borers?

Squash vine borers are the larvae of an orange and black moth. These diurnal moths are active during the day and lay their eggs on squash plants. Once the eggs hatch, the larvae burrow into the stems of the plants and feed on the internal tissue, eventually causing plant death. The adult squash vine borer moths can lay up to 150 eggs in a single season, making them a significant threat to squash plants.

The larvae of squash vine borers are particularly destructive because they feed directly on the vascular tissue of the plant. As they tunnel through the stem, they cut off the flow of water and nutrients, leading to wilting and eventual plant death. The presence of squash vine borer larvae is often accompanied by sawdust-like frass near the base of the stem, indicating their activity.
