Hi I'm in lebanon I have a problem from bed bug I want them to die all cause they eat what is the medicine? Please help to kill them what is trhe best best medicine?

An exterminator. Bedbigs can live through most poisons these days and the experts are having to look for new resources such as exream heat.

You can also do it yourself if you have the right combination of bed bug spray (http://www.domyownpestcontrol.com/bed-bugs-c-39.html)and know how to use it. Basically anything an exterminator will do can be done by yourself, but you might have to reapply the stuff if they aren't killed right away which is usually the case.
