Can I break my lease for brown recluse spiders?

I have since January this year now had my apartment sprayed 3 times. The apartments were told by the exterminator that the spiders are in my walls and not coming from outside. He told them I need baseboards put in my closets to keep the spiders out. That was nearly 2 months ago and the apartments told me the guy who does baseboards does it whenever he feels like it...so they don't know when it will happen. Can I not be released from my lease...I've been there year and a half, but my lease does not end until Jan. 2013. Or if possible can I not be transferred to another apartment complex that the property company owns?
