Can Wasps See in the Dark?

No. Wasps are diurnal (day-active). Their compound eyes are adapted for bright light—excellent at detecting motion and UV patterns (flowers, prey) but poor in low light.

• No ocelli (simple eyes) for night vision (unlike some bees).
• Navigation relies on sun position and visual landmarks.
• At night, they return to nests and become inactive.

In a dark house, a wasp cannot effectively see or navigate. It may crawl or fly erratically if disturbed, but it's not "seeing" in the dark. Turn on a light, and it will orient instantly.
