Bedbugs

Hi

Long story in short: I have inadvertently brought bedbugs home from my work place. Management knew there was an issue with bedbugs in my work, but opted for cheapest possible solution to fix it. As a result, there are some areas crawling with bedbugs. A colleague also brought home bedbugs in much the same way and managed to infest his girlfriends flat. I have just spent an unpleasant weekend trying to spray my bedroom, and steam-clean every nook and crannie. My wife is bitten to hell and gone and I'm going out of my autistic brain! 

Can I hold my employer responsible for this mess? And would it be unreasonable for me to ask him to pay for a professional pest control person to sort my house out?
