there are many websites that will help you tell the difference between flying ants & termites. Google termites vs. ants and you will find what you need.

It is now August and I can't remember what the body and wings exactly looked like but based on what I am now researching, I might have been had by the termite company. If they told us that we had termites when we really had ants I am cynical enough to believe that is what these companies do if they can, in order to make money. The things did not fly, and were dark in color. Hower they did shed their wings. When DH and I saw the hundreds of them on the floor we panicked. However they did shed their wings.
What do I do now? Should I just chalk it up?

Ants have a pinched-in 'waist' and termites don't.

If there were that many inside your house all at one time it could very well have been dry wood termites. have/had you noticed any small sawdust looking mounds any where in your home before this happened? I had a similar experience years ago when I lived in an apartment in Ohio. Before the bugs I kept noticing sawdust under my bedroom door and just thought it was something caused by the new door rubbing on new carpet. When we did research when we saw the swarm we put two and two together-removed the door and took it outside and it was full of termites! This was a new door and apt manager and pest control figured the door was manufactured somewhere in the south since this type of termite was not common where we lived.

Thank you all for the information. It is possible that I have termites above a window in that room and the tech is coming back to take the wood molding off. If it is termites in that spot, he will put something on the wall to kill the termites in that area.
But those things never flew, could they be termites if they crawled in from somewhere? Now in August I can't remember exactly what they looked like,it was in May.

I guess you will know when he takes the molding off. Hope you get it taken care of soon--let us know what happens.

We had termites once and they did not fly. Just huge amounts of them crossing the floor and leaving behind wings.

Did you try to kill any when you saw them? I know I did and (I know this is gross) while ants "crunch" (due to the exoskeleton I guess), the termites just skwooshed.

Good luck.

Interested to find out what the outcome is when person comes, however, in the meantime, maybe if the ants were biggish they were carpenter ants, which are just as bad as termites, little buggerz will eat your woodwork including the bits that hold your house up, just the same.

Termites eat wood as a food source so you will not see any wood residue around your home if it is termites. Black ants will destroy a home faster than termites will. They eat thru wood to get to where they want to go, they do not eat wood. Therefore, if you see 'pencil shaving' like material by the window sills, under your sink, etc. it is ants.
