In previous summers, Lauderdale County authorities sprayed rural areas from 7:00 p.m. until 2:00 a.m. to try to control the mosquito population.
Then a doctor from Mississippi State University appeared before the supervisors to discuss the procedure.
"He told us in so many words that what we were doing was good, say from 5:00 p.m. to 7:00 p.m., but after that it was ineffective as far as controlling any mosquitoes in Lauderdale County," said county engineer Neal Carson.
But the county had established a budget and purchased chemicals and equipment, so until this summer, they used it.
"We started about four years ago, if my memory is correct. We started, of course, when the West Nile virus became evident in this part of the country," Carson said.
The total annual budget has been about $70,000. The spraying equipment is still available, although now it is only used for spraying at special events such as baseball games.
"We're going to budget spraying for next year, too, and we're going to just have a sort of wait and see, to see if we need to go back to a scheduled spraying like we've done in the past," said Carson.
The city of Meridian still sprays each night, running two trucks, in the belief that is the best way to control mosquitoes.
