Bedbugs in the Duvet: An infestation on the Upper East Side

Actually getting rid of the bugs can be nearly impossible. Most insecticides which are legal aren't strong enough to do a good job, so you end up having to resort to really extreme, flat-wide methods like steaming the entire flat. It costs a fair bit of money, and isn't always effective - particularly if the infestation actually came from a nearby building, in which case it might come back by the same method.
In my case, we ended up moving out, after trying pretty much everything.
We still had one or two stray bedbugs that managed to survive on luggage or something like that and made it onto our new bed. But we wrapped it in cling-film (aka Saran-wrap) for a few months and we've been completely clear ever since we took it off.
It's really not very pleasant...
Some advice - look at the corners of the mattress at every hotel or hostel you stay at for the black dots or an inky stain.
After checking google for bedbugs here in Vancouver I noticed that same site and was shocked to see the amount of reports. There's hardly a block in the city which hasn't experienced problems. So, even if you're cautious & clean you can still get affected by your next door neighbour.
We got the pest control guys out and they reduced the problem but werent able to get rid of them.
the best thing that we found to deal with them is Diatomaceous Earth - http://en.wikipedia.org/wiki/Diatomaceous_earth
Make sure you get the food-grade kind, not the stuff they use in pools
Sprinkle it on the floor around your bed and clothes racks/cupboards and leave it overnight. In the morning vacuum it up and throw the vacuum bag out. Repeat daily for about a week or until you notice the number of bedbugs or irritation decreasing, then start increasing the amount of time that you leave the powder out for.
Its also good to check for them everynight before you go to sleep. Be sure to check under your mattress, and all around your bed frame.
We would collect them in a jar and them leave them in the sun to make sure they were dead.
We had our bags cryogenically frozen when we got home, I'm not kidding. The extreme temperature kills them off. It seemed to work, no bedbugs survived if they did manage to get into the bags.
I feel so bad for them :P
