I find that carpet harbours dirt, dust and creepies in the fibres more than anything so I don't have carpet in my room anymore. It is chilly underfoot but it is worth it to prevent being bitten. Vacuuming the mattress is supposed to help too and then spraying with the anti-bedbug for good measure should get rid of the critters.
