The biting flies

What's up with this? The usual summer is unfortunately filled with biting bugs outside. We have deer flies, horse flies, and the normal mosquito. Isn't that enough to deal with when you are trying to have a good time outdoors? But this year we have something a little different. Regular flies that bite.  They seem to be a little bit smaller than normal but I found out that they have a big bite. These are ridiculous because they seem to be an expert at getting inside.
