Although the traps are in fixed locations during the test season, Shaffer says they can contact the health community and ask for a trap in their area.
"The traps are specially designed to inspect the mosquitoes," Shaffer said, "They are not really meant to reduce the number of mosquitoes in the environment on a large scale."
Mosquitoes are naturally warmed by warm weather "Wherever water puddles and stands for about a week is a breeding ground for mosquitoes," he said.
Residents should inspect objects that tend to accumulate rainwater Common mosquito breeding sites include tires, buckets, gutters, and any outdoor equipment.
Items designed to hold water should be periodically cleaned or maintained in a constant circulation, and, according to Shaffer, should be emptied approximately every six days
"For agricultural environments where there might be watering for cattle, goldfish can be put into the water and they will the mosquito larvae eat, "said Shaffer.
Mosquito-borne diseases can be prevented by wearing long sleeves and pants while staying out of the main mosquito activity, with the window or shield closed, and using EPA-approved repellents containing the active ingredient diethyltoluamide (DEET
"People should understand that we care in Clark cCounty for mosquito-borne diseases, but they should assume that the disease is out there, and always take precautions," Shaffer said
Should be a case of West Nile virus is identified in Clark County, a press release from the Department of Health is released via the media, according to Shaffer.
