Who knows about insect bites?

My daughter and I just noticed red little dots on our skin and they itch. But what is odd is that they seem to be in a pattern of 4 dots.
kind of like this

Does anyone know what this may be?

It's really hard to say without a little more info. If these dots are located in places where clothing fits snuggly, such as waistbands of underwear, bra or cuffs, and they itch particularly at night, then what you may have are scabies. They are tiny little bugs that burrow under the skin, usually in a fairly straight line, and leave a little red dot/blister behind. They are cured with a body shampoo/lotion, available by prescription from the doctor. Actually, a visit to the doctor is really in order here to get a final diagnosis. You could have odd flea bites, they could be bedbug bites, or any number of things. In addition to being treated yourself, you may need to treat the entire family, and do some in depth cleaning at the home. Sorry, I understand how rotten this news is, wish I had better advise to offer you. But you really do need to see the doctor.

spider bites are side by side like that, but I don't know about top to bottom like that.

look up scabies.

probably spider. Put sunscreen on the bites, it helps the itches and swelling
