Clean all your bed covers, bedsheets, blankets clothes by hot water regularly.

keep hygiene and check all the corners of your bed and cot and apply the spray and kill them.

change the bedsheets and bedlinen regularly and wash them in hot water.

Cover all the openings in cot or in wall completely as they like to stay hiding there.
