I too had bed bugs. No idea where they came from. Maybe because of the new bed frame that my dad purchased a while back when I was still living with my parents.
What we did was to remove the bed, looked through at every nook and cranny, removed the bed bugs manually and squishing them.
For the bed frame, it came with a overlaying velcro cover, this was removed and send for dry cleaning.
The frame itself was thoroughly cleaned, sprayed with cans of Baygon and using a stand steam iron, cleaned. I think we killed about 100 plus bed bugs and now the bed is bed bug free.
Scary bit about bed bugs is that they can go on living without a blood meal for 6 months or more and they can hide in every nook and cranny.
