Once you get bed bugs you need to get your place treated for the bed bugs to get them to go away.
When the bed bugs get into your home they will not go away on their own and will actually increase in infestation so you need to have an exterminator come in to get rid of the exterminators.
I've used some home remedies before to get rid of bed bugs and they did work somewhat but I found it worth the money to just hire a professional exterminator to get rid of the bed bug infestation in my house.
You can kill off some of the bed bugs and the bed bug eggs using some rubbing alcohol but if you have a complete infestation you really need a professional exterminator with the knowledge and equipment to get rid of the bed bugs.
It will be money well worth spent.
