Aedes mosquitoes breed in small containers of standing water: buckets, plant saucers, tires, toys and clogged gutters. Their eggs can survive dry for months, so empty and scrub containers weekly.

Local help

New Orleans has its own city agency for this: the Mosquito, Termite & Rodent Control Board handles mosquito, termite and rodent work on city property and does public outreach. At home, follow the CDC rule and dump standing water every week.

What works at home

Supplies: mosquito dunks.
