Answer: What you describe sound like chiggers. Chiggers, which are also called harvest mites or red bugs, are very small and can not usually be seen without a magnifying glass or microscope. They can cause dermatitis in sensitive individuals. I'd treat the lawn to get rid of the pests, before their populations become so large that they attack when you're simply standing near the lawn. There are several products labeled for chigger control, including carbaryl (Sevin), diazinon or cyfluthrin (Tempo).
