Does permethrin kill fleas

Yes, possibly. It is toxic, so avoid contact with skin and don't inhale it.

The problem with modern bed bugs is that they are increasingly resistant to chemicals and have developed "super-bug" status. Increasingly bed bug specialists are turning to chemical free solutions to avoid this problem.

If you are looking to self treat, reading up on the products you plan on using and the best way to use them is essential although professional experienced help is almost always recommended.

Warning: The liquid form of permethrin is VERY toxic to cats. Make sure everything is very dry before allowing them in the area.
