Mosquito bites but I haven't seen any mosquitos?

I just bought a house in December. In the back yard about 200 feet away is a large section of woods. I do not have any standing water around my house nearby. Just in the last 5 days I have had so many mosquitos bites. And I may add, the bites are in "not the obvious places" one would get mosquito bites. I have a few on my legs but the others are near my groin area and on the middle of my back.
I also use that Avon Skin So Soft.
Thing is: I never see any mosquitos! And these welts I am getting are pretty big.
Just a few hours ago, I was sitting in my office chair in my den working at the computer here; got up to take the dog out; .we were out there for abotu 3 minutes. Came right back in. I went to the bathroom and noticed I had 2 more bites on my upper thigh near the groin area.
I never feel them bite nor see them...so what can I do to prevent these? Could they have gotten in my house somehow? H E L P !

Have a dog? They may be flea bites. My neice had them when she was little. Damn the little buggers. Or check under your mattress for bedbugs, lice, or chiggers,esp around the edges of your mattress and boxspring. People don't feel them when they bite, but the bumps come a day or so later. So you may not have gotten the bites outside. I'd do a really good mattress/boxspring check if I were you. It doesn't mean your house is dirty or anything like that. You can bring them in on your clothing or in a suitcase that you had somewhere else (such as a hotel). It happens.

It sounds like your house is infested with spiders! Get a couple bug bombs and bomb the place! It seriously sounds like spiders because one time, I was the victim of a spider nest attack in my bed. Or mabe it's some other type of bug, fleas mabe? Bomb and then deep clean!!

you don't need to see mosquitos to have a "bite". it's summertime in the Northern hemisphere and skeeters are normally occuring. try using bug spray.

With the deep woods you don't need to have any standing water to have mosquitos and you don't need to see them either.

When going outside take a dryer sheet and wipe any expose areas done with it then put the dryer sheet in your pocket....It's supposed to repel mosquitos....at least it works for my sister in law and several other people I know....I use deep woods off personally.

Your sure they are mosquitoes not spider bites. If they are you might also need to bomb back yard close to woods for mosquitoes.
