Horry County Mosquito Control may begin truck-mounted mosquito spraying operations on Tuesday, May 5, 2026.
The spraying will be conducted Monday through Thursday from about 30 minutes prior to sunset until around 11:30 p.m. This schedule will continue as weather allows.
This doesn’t mean spraying will happen every night, just that crews will spray when conditions call for it and as weather conditions, such as rain, wind and temperature allow.
Horry County only uses products approved by the EPA and DPR. The product poses a minimal risk to humans or animals. Individuals with asthma or other respiratory illnesses may wish to stay indoors and close windows and doors during spraying. In addition, homegrown fruits and vegetables should be washed, scrubbed, and/or peeled before eating.

To help keep our local honeybee population safe, beekeepers are urged to contact Horry County Stormwater to identify the location of their colonies.
