Yea I know of a apartment complex that had to treat twice for Bed Bugs, and cost the owners $7,000 dollars. To kill the little bastards. I wouldnt go in there unless the pest people were there first a few times to treat all areas. These critters can even get into lite sockets and stay there and go through walls behind base boards to get into another unit and infest it as well. Let the Pest People do there job 1st. then go to clean the carpets. And Be Careful not to bring them home with you, or you're costs can exceed $1200 bucks or more to treat. Ide pass on this job, could end up costing you Big $$$$$, if they get on you and hitch a ride to you're home. Ive had them in 1 of my apartments, Cost $1100 to have Loyds come out. 8 trips . and they don't treat the sofas, they are not allowed to spray furniture in California. So either throw away the sofas, or have them put in a storage container and heat them up to 150 degrees for 2hrs. to kill the little bastards. And the Proto call is a Beach to follow, must get mattress zippered bags $150 each. Wash All Clothes, Pull everything out of dressers drowers ,take all clothing out of home and wash in Hotest water possible at landurey mat . Forget the job go on to another, and don't Vac the Carpet, you'll be bringing thoses little bugs to some one else is Home. Postaldave
