Thank you for replying back.
Yes,it is quite possible & common that chiggers are on your bed sheets or matress.
Chiggers are tiny little bugs which are invisible to the eye. Wash your clothing in hot, soapy water. Soap and water usually kills the chigger larvae.
Where you are dealing with chiggers on clothes, permethrin is quite effective. It acts as a repellent but should only be applied to your clothes and not directly to your skin.Apply the repellent to clothing by rubbing or spraying it on.
Strip off all bedding and pillows. Soak and wash them in the hottest water they can stand without getting spoilt, use bleach on appropriate fabrics and dry them off on high temperatures.
All this will help you greatly to get rid off from these chiggers.
Apply ice as explained above.Take tab.Beenadryl & tab. Ibuprofen 400mg from your counter.It will reduce the swelling.These will help you greatly to provide dramatic relief from this severe itching & other symptoms.
If you still have any questions,please let me know..I am happy to address your follow-up questions.
God bless you & take care.
