DALLAS COUNTY -- Workers from McAllen, Texas, have joined Dallas County's war on West Nile virus as part of the state's provided assistance of extra workers, fogging trucks, and chemicals.
Mosquito control is aggressively trapping and tracking Dallas County's mosquitoes.
Tuesday night's rain, say experts, will have a huge impact on the population.
"Rain is a good thing," said Dallas County Health Department Entomologist Scott Sawlis. "One, it flushes out all the storm drains, so the house mosquito breeding sites get flushed out -- so that's good. The bad; it prohibited our grand spraying attack last night."
Sawlis said the rain also exacerbated the problem of standing water. Water that doesn't dry up will become breeding sites for a future generation of West Nile carriers.
Some experts believe that may make this the optimum time for aerial spraying. Adult mosquitoes haven't had a chance to breed or lay eggs yet. Spraying from above Thursday could make sure millions of grown-up mosquitoes don't get that chance.
Dallas County will continue it's ground spraying attack Wednesday night. The original plan was aggressive targeted fogging three nights in a row.
"We still think the three days is going to be significant," said Dallas County Health Department Director Zach Thompson. "It's just not going to be the three days in a row, but it'll be three days that we will having spraying."
Experts hope last night's interruption doesn't give mosquitoes a chance to rebound.
