<human>: Tell me what kind of bug would be in a bed it is tiny, but visible to the naked eye? They are round and black. they are smaller than a blackberry seed. Is this a bed bug? What can I do about it? They bite and the area swells and gets quite itchy. I sprayed the mattress with Lysol disinfectant and we didn t get bit for awhile I also washed blanket and sheets with hot water with bleach. Thank you, Evy Ross
<bot>: Hi Eve Ross, Thanks for posting in Chat Doctor. Swelling and itching at the site of insect bite is mainly due to allergic reaction. Tiny bugs on bed are usually bed bugs. You don't have to worry much and do the following:For swelling, you can take Paracetamol with ibuprofen combination. For itchiness, take an antihistamine like chlorpheniramine male ate or Cetirizine. You can also apply calamine lotion. It is good that you have washed blanket and sheets with hot water and bleach. You can also use organophosphates based sprays which could kill and prevent these bugs. It might take 2-5 days for the area to heal. Keep it clean to prevent the area from infection. Hope this information would be of much help. Take care.
