I have been getting random bite marks but see nothing biting me. For no reason I start itching in different parts of my body and when I start scratching, red mosquito looking bites appear. Sometimes single or 3-5 together. Not all over the body. They itch like crazy for a few days and then leave red marks. Not bed bugs assured by the Orkin man. We have vaccumed the matress etc with a heavy duty vac. This itching appears randomly not in bed. could be at a store, someone s house, outside. Two times I have had none for a week and then the itch starts again Seems no ryhme no reaon. Been going on since the end of August. thank you for you help!
