anything else they could be besides mosquito bites?

Hi,
Welcome to the ehealthforum and I am glad to help you out.

These bites can be due to insect bites or arthropod bites. Firstly, it is important to keep the area clean. Wash the area with some antiseptic lotion or soap. Use cold water but avoid the use of warm or hot water as this may tend to stimulate itch. You should not scratch the area as it may lead to open wounds and secondary infections. You may apply a mild steroid cream like hydrocortisone cream and take anthistaminics for itching after consultation from your dermatologist. You may also need oral steroids and a course of antibiotics.

If there is any fever or bull's eye rash then Lyme's disease and tick bite fever should be ruled out.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
