Will these Termite Swarmers or Winged Ants cause problems?
Forget about spraying. First, you should collect some of them for identification. In a ziploc bag in the freezer is fine. Second, you need to know if you have termites or ants. The differences are quite easy to spot once you know them. There’s a checklist of differences at http://drdons.net/biology Thirdly, these flights are seasonal, Spring and Fall, in the sort of weather pattern you describe. It is termites from mature colonies heading off to try and mate. Only a tiny, unbelievably low, number of these ever get to build their own colony. Mostly if you spray, you’d be poisoning the losers and these hapless insects are important in the food chain. Fourthly, it is a shame that you didn’t see where they were coming from. Basically, there are mature colonies close to your house that could attack it and may already be doing so. You should arrange a competent timber pest inspection some time in the next month or so.

If you are a homeowner or want to buy one, get your home checked for termite. A yearly termite inspection in locations where these insects are known to be present is a smart move.A termite inspector is an expert who can locate these pests before they start destroying the wooden structures in your home. http://www.askaquery.com/questiaon/Termites-at-Home.
