Dallas County officials said there are four times as many mosquitos compared to this time last year – but the West Nile infection rate is much lower.
The director of Health and Human Services says the rainy weather in July is a likely reason for the spike in the number of mosquitos and still urges caution.
"We know that there are mosquitos out here that have the West Nile Virus our traps are identifying that so we encourage everyone to definitely use insect repellent," said Zach Thompson, Health and Human Services director.
In 2012, there were 19 deaths in Dallas County and nearly 400 human cases of West Nile.
So far in 2013, there are just three confirmed West Nile cases and no deaths.
