Late summer to early fall is when yellow jackets are most active and aggressive, as colonies reach peak size.

No, nests are abandoned in winter. However, new nests can be built in the same area the following year.

Yellow jackets are slimmer, have bright yellow and black stripes, and are more aggressive than bees.

Most yellow jacket treatments are completed within an hour, with results noticeable within a few hours to a day.
