I also had this problem and following is the method that I used to destroy the bed bugs. 1) Steam clean the entire bed frame and mattress (At this high temperature, all bugs will be dead) 2) Vacuum the entire bed. (This way, it will cleanup all the dead bed bugs from step and any possible eggs) 3) Use bed bugs medicine around the bed frame and the mattress (http://www.enta.com.sg/) 4) Repeat step 1-3 once a week till 3 months later. then reduce it to 1 a fortnight then to 1 a month for about 1 year or 1.5 years. I am not kidding!!! please note that they are able to go without food for 1 year. so you must be diligent to completely eliminate it. As humans, you carry may carry the eggs and bugs around. the best method for this is to introduce steam cleaning in your home. This way, you will also kill another germs in the home. If you have school going children, they may bring it back from school or bus. so good luck.
