Help, I just found tiny bugs in my pantry!!!!?

I am freaking out right now!! i pulled a pot out of the food pantry and the lid was covered with tiny bugs. i have looked up pantry bugs and cant find any that look like these. they are really tiny, they look like mites that you find on a wild animal. when i started going through everything and put it all on the table, i was horrified to find that almost all of the food was covered. i just threw 5 bags of food away. i dont kow what else to do. how do i get rid of these things? i dont see anymore, but will there be more? has anyone ever had these disgusting pests and what do you do to get rid of them for good and prevent them from coming back? will they spread to the other side of the kitchen where i have the rest of the food? i have to go shopping now that i got rid of all of our food, but can i put the food in the pantry?
