GREEN BAY (NBC 26) -- The Shorewood Golf Course says the mosquitoes are the worst they've been all season.
"They're a nuisance so you know, you go for one and you kill five,” said golfer Mike Cheney.
Mike Cheney and Tom Steffen were spending the day on the links, fighting off mosquitoes with every swing.
"I usually stop, I usually stop and hit the mosquito, and then go ahead and swing, but you do lose your concentration if you're swinging and you get bitten," Steffen said.
Carol Bess, an infection prevention team leader with Bellin Health, says there are some risks if you're getting bit
"I think the biggest concern, always with mosquitoes, are any type of illness that you can get from a mosquito bite,” said Bess.
Those illnesses of concern include West Nile or local reactions.
"If you get infected by West Nile, for example, or some other type of mosquito born illness, usually what you'll typically experience is fever, headache, body aches, muscle aches," said Bess.
She says it can go on to be more severe.
So, what can you do so you can stay out on the course while staying safe from mosquitoes?
"Insect repellent, clothing that covers your skin, the more skin that you have covered the less there is for a mosquito to get at."
She also says it's important to get rid of standing water. Golfers say they're trying to make sure their shots stay straight so they don't end up in the trees where they say the mosquitoes are worse.
"Swat them and get moving on as soon as you can," said Cheney.
While some golfers may be leaving the course with more bites than they came with, it's sure not keeping them off the course.
