Mosquito Nets

Just wondering about Mosquito Nets for our trip to South East Asia.

We will be staying at budget accommodation (hostels and cheap beach huts), and was wondering what we should do about the nets?

Do most places have them for people who stay there?

Should we take our own just incase?

If so, how do we go about hanging them?
Obviously we would just have the net, and surely places wont have something on the ceiling to hang them from?

Any past experience on this would be very appreciated.

Cheers

I was wondering about this as well. Also, what's a reasonable price to pay for one? The ones I've seen are around £30 which seems a bit much for a net.

..i have never used one....most of the places I stayed in had one up already....!? if they didnt..i used more repellant...!
