VX those are red bugs or chiggers, cant seem them easily but they get into ankles, waist, and unfortunately crotch. Very bad during warm months along with ticks, particularly in the forest. Best to wear socks and shoes and spray all clothing before hand with Permathone (I did before meet and no bites), which will keep them all away. Once you have the bites it will take a week or so for them to heal, red bugs inject a venom that keeps them itching, so try not to scratch, keep it clean. All hunters no these lessons well.
