Is this is What the Air Force is For?

According to the Minot Daily News (Minot AFB- I joined the Air Force to see the world and I saw Minot for almost Minot AFB for 4 years), the Minot AFB is going to spray for mosquitoes around the AFB and the City of Minot. http://www.minotdailynews.com/page/content.detail/id/528884.html?nav=5010
While I am for the military to help out the community they are close to, is spraying for mosquitoes in the city, (the AFB is about 20 miles north of the city) a legitimate use of the Air Force? To me, no it is not. The Air Force is supposed to be used for the safety of the United States, not for the spraying of mosquitoes.
