Mosquito Control-Post Hurricane IRMA

Mosquito Control officials say recent rain fall due to Hurricane Irma has created the perfect breeding

grounds for mosquitoes. Sumter County received an estimated 8.5 – 12.5 inches of rainfall throughout the

county. With the recent rain fall and increased temperatures, adult mosquito populations will soon

flourish (5 to 10 days). Spraying (adulticiding/night spraying) operations are scheduled to begin on

Thursday, September 14, 2017, and continue through Sunday, September 17, 2017. The mosquito control

operations will be focused on the most congested residential areas of the county.

Mosquitoes of the pest and nuisance breeds are most prevalent after flooding situations; however,

mosquito breeds that are known disease vectors (carry and transmit disease) may also be present. Officials

want to encourage residents to remain vigilant around their homes and eliminate all mosquito breeding


Tips for controlling mosquitoes around your home:

 Remove standing water in old tires, buckets, drums or any other container.

 Check clogged gutters and flat roofs that may have poor drainage.

 Empty plastic wading pools, bird baths, and pet water bowls at least once a week.

 Drain water from boats being stored.

 Fill in tree holes and hollow stumps that hold water.

 Stock your ornamental water gardens with mosquito-eating fish (Gambusia, minnows or gold


 Repair screening on windows, doors, porches and patios.

 Drain water from old pools not in use.

Tips for avoiding and repelling mosquitoes:

The 5 D’s

 Dusk and Dawn – Avoid being outdoors when mosquitoes are seeking for a blood meal. For

many species this is during the dusk and dawn hours.

 Dress – Wear shoes, socks, long pants, and a long sleeve shirt when outdoors for long periods

of time or when mosquitoes are most active. Clothing should be light colored and made of

tightly woven materials to keep mosquitoes away from skin.

 Drain – Reduce the amount of standing water in or near your property by draining and/or

removing it.

 Deet – Use an insect repellant containing Deet. Spray clothing with repellents containing

permethrin or Deet because mosquitoes may bite through thin clothing. Always read the

manufacturer’s directions carefully before you put on a repellent.

Mosquitoes generally are more prevalent in wooded and swampy areas, and tend to be most active

during dawn and dusk hours. Use insect repellent before going into high-risk areas or when outside

during high-risk times. The most effective protection may be obtained through the use of products

containing at least 20-30 percent diethyl toluamide (DEET)*. Follow the directions carefully and do

not over apply. Extra care should be taken with children under 5, adults over age 55, and those with

weakened immune systems due to chronic illness, as these populations are at a greater risk from

mosquito-borne diseases. Proper vaccination of horses will protect them from contracting Eastern

Equine Encephalitis and West Nile Virus. Don’t forget about your pets; mosquitoes are known to

transmit canine/feline heart worms. See your veterinarian and place your pets on a heart worm

preventative medication today.
