With spring in full bloom, D.C.’s Department of Transportation will start its annual tradition of spraying ginkgo trees Monday night.

It’s an effort to limit the growth of ginkgo fruit, which can mean a stinky experience for passersby, bystanders and, well, most everyone.

DDOT said it will use the same spray it has used for the past 20 years, “Shield-3EC 24(C),” from 9 p.m. Monday to 6 a.m. Tuesday, weather permitting. It plans to start in Ward 5, then move onto wards 4, 3, 1, 2, 6, 7 and 8 over the course of several nights.

Important note here: DDOT said cars don’t need to be moved.
