 “Help! Help! Help!” a resident screamed over the phone, “I am being eaten alive by mosquitoes!”

Recent rainfalls have produced an early hit of blood-seeking mosquitoes．Once flooded, eggs laid during the drought（干旱） along water banks hatch（孵化） quickly, flying off to seek hosts such as people, birds, and other animals．

The flood mosquitoes are big and aggressive．They chase you down, drill into your skin and take your blood, causing pain and itchiness．“I have lost a pint of blood to those suckers,” a Spring Hill resident claimed．“Mosquitoes are killing my kids,” a Ridge Manor woman shouted．

Residents are urged to protect themselves when going out, especially during the hours of dusk and dawn．Long-sleeve shirts, long pants, socks and hats will help keep mosquitoes at bay．

Mosquito Control has already received hundreds of service requests this month．When calling in, residents need to provide their name, address, phone number and nature of the problem．Technicians will respond by looking into the problem and making proper treatment．

Mosquitoes grow in almost any kind or amount of water．Controlling mosquito larvae（幼虫） is important to mosquito control．Kept in their water habitat, larvae are treated and killed before they mature and “take to wing．” Field technicians check their areas searching for mosquitoes breeding in lakes, ponds, drainage ditches（排水沟） and they treat the water with a host of larvicides．

It is important to understand that mosquito control is much more than sending a spray truck （airplane or helicopter in other counties） to kill adult mosquitoes．Night-time spraying is actually the last defense after all the above procedures have been done, but there are still mosquitoes present in the area．
