H Lorena. One of the hardest bugs to get rid of, you must be diligent. Take all the bedding out and put in the hot sun. Lift your beds and put shallow cups of bug spray under the legs. Put all your clothing out in the hot sun for several days and take baths in the morning and in the evening. Vacuum every morning and every evening. Eventually you will rid your area of the bugs. Going forward, spray with bug spray on a regular basis.
