Does bed bug spray work?

Dont know about that spray but try this

Things You’ll Need:
Lots of garbage bags or XL Ziploc Bags.
Mattress and box spring covers for each bed in the house.
Vacuum cleaner.
Washer and dryer.
Exterminator.
Step1Vacuum everything. Once you have discovered that you have bed bugs the first step is to vacuum everything. You will want to vacuum the carpet around the bed, the mattress, the box springs, and any corners or cracks in the bed frame.
Step2Get rid of the vacuumed up stuff. You will want to bag the vacuum cleaner bag in a garbage bag, tie tightly, and throw away. If you don’t have a vacuum with a bag, dump it into a garbage bag, tie tightly, and take it out immediately. You don’t want bugs you have sucked up to crawl right back out.
Step3Cover your mattress. You will want to cover your mattress (and preferably your box spring as well) in a cover. This is one made of thick fiber that doesn’t let the bugs through or one that is made of vinyl. It will be zipped around your mattress and completely close your mattress in. This traps bugs inside the mattress (keeping them away from food sources) and eventually they will die (they can go for months without eating so you will want to leave the cover on for 18 months or so before taking it off for any reason). You may also want to tape around the zipper to make sure that none are escaping through any small holes.
Step4Wash everything that can be thrown in the washer. You will want to wash your bedding, curtains, and other washables in hot water. Then dry them in the dryer for at least an hour to kill of bugs, nymphs, and eggs.
Step5If it can’t be washed then it is a good idea to bag it up in a XL Ziploc bag or a trash bag tied really tight. You should then put it outside. If it is hot out then you can bake it in a day, however freezing takes longer and in between temps means that you should keep them outside for a long time. Black plastic bags can help to heat up the materials inside (which should get to over 113 degrees Fahrenheit to kill the bugs).
Step6Get the exterminator. There are many products out there that claim to get rid of bed bugs and if you want you can try them. However, many people report having paid for the do-it-yourself stuff and still had to hire and exterminator. It is fastest if you call the exterminator right away. (You can actually do this before beginning your cleaning regimen so you will be ready when he arrives). Follow all instructions carefully because bed bugs are very hard to get rid of and you don’t want him to have to come three and four times to get rid of them.
