Excellent post! I've been battling a pest issue for months and wasn't aware that cockroaches can actually bite until I found myself with weird spots on my skin that looked nothing like bed bug bite remedies (
asteroidsathome.net) bites - the roach bite signs included mild swelling and itching that persisted for about a week, so I tried a simple cockroach bite treatment with antiseptic cream and ice pack which lessened the reaction - luckily no major issues developed but I certainly suggest hiring a pest control professional immediately because stopping infestations is far superior than treating pest bites after the fact!
