Hello. My 7 year old son has 2 insect bites that I assume are from spiders but honestly do not know. i do know that on the days he was bitten he was wearing long pants so again I assume Mosquitos can be ruled out but again who knows. Anyways, both bites are red, swollen, itchy, warm, hard, and painful to touch...... Help? Also west Nile was found near our home recently!!!
