Cobb & Douglas Public Health Offers Free Mosquito Larvicide Tablets
Cobb & Douglas Public Health | September 24, 2026
Distribution: Friday, Sept. 25–Oct. 30, 2026; While Supplies Last
The Georgia Department of Public Health has reported increasing West Nile Virus (WNV) activity in Georgia this year (including in our district), and mosquito season typically continues through October. Larvicides help control mosquitoes before they become biting adults.
Cobb & Douglas Public Health is providing free mosquito larvicide tablets (Mosquito BTI Dunks) to help primary homeowners reduce mosquito breeding around their homes and decrease the number of mosquitoes that can spread mosquito-borne illnesses, including WNV.
All homeowners are still encouraged to “TIP ‘n TOSS” outdoor water in receptacles such as bird baths, tires, planters, pet bowls on a weekly basis. Larvicide tablets are only recommended for sources of standing water that cannot be easily drained or eliminated.
HOW DOES A RESIDENT GET THE FREE LARVICIDE TABLETS (MOSQUITO BTI DUNKS):
Beginning Friday, Sept. 25-Oct. 30, residents of Cobb and Douglas Counties can receive one (1) pack (of six (6) tablets) of DUNKS BTI larvicide per household.
Residents can pick up the larvicide tablets (Mosquito Dunks) at any of the following locations:
- Marietta Public Health Center, Building A – front reception desk
- Acworth-Kennesaw Public Health Center – front desk
- Smyrna Public Health Center – front desk
- South Cobb Public Health Center – front desk
- Douglas Public Health Center – front desk (Beginning the week of 9/28/26)
If a resident does not have a home in Cobb or Douglas County, they are not eligible for the free larvicide tablets (Mosquito BTI Dunks), but can check with their county health department or local home improvement store for similar supplies.
DOES USING LARVICIDE TABLETS (MOSQUITO BTI DUNKS) TOTALLY ELIMINATE MOSQUITOES?
No. Larviciding is just one tool in mosquito control.
