When Is Yellowjacket Season in Chicagoland and Northwest Indiana?
Yellowjacket activity in Chicagoland and Northwest Indiana typically peaks between late July and early October. These aggressive stinging insects become more noticeable during late summer when their colonies are fully developed and their food sources become scarce.
