Town officials in New Hampshire are preparing for mosquito season.
WMUR-TV reports crews in Rye will start spraying for mosquitoes this week. Officials say they will check standing water for mosquito larvae. These areas include swamps, salt marshes and ditches.
Scientists say mosquitoes and other insects like fleas and ticks weren't affected by the extended period of subzero weather in northern New England.
Officials say they hope to prevent the spread of West Nile and Eastern Equine Encephalitis. West Nile can produce a fever, head and body aches, skin rash and swollen lymph nodes, though sometimes people show no symptoms. EEE is rarer but much more dangerous, potentially causing brain damage or death.
