Question
What do I bait racoons with for live trapping in my attic?

Answer
I assume you mean cage trapping rather than using other live traps such as footholds or species specific traps.

There are a number of baits you can use. Sardines, in oil, strawberry sugar wafers, molasses and honey, pizza (pepperoni or other meat based pizza).  Dry dog or cat food can also work.

Understand that using meat based baits in the attic will rot relatively quickly so be prepared for flies and odor. Change the bait every two days to reduce this problem.
Removing a raccoon from the attic needs to be planned as if you bring the raccoon through your house, you need to be prepared for the possibility of it defecating while you carry it. I would suggest, putting the trap in a plastic back after capture and before carrying it through the house to catch urine or feces before they hit your carpet.   Make sure the trap door won't open prior to moving it as well.

For disposal of the raccon be sure to follow your state law. Euthanasia info and the cruelty of translocation info can be found at  http://icwdm.org/wildlife/euthanasia/default.asp  

If you have a female that has had young in the attic, then catch her and go up in the attic (make sure you have the right female going in an attic for young can be dangerous) and remove the young by hand. (Preferably a gloved hand with good strong leather gloves or cat grasper, there is a chance they can bite and when picked up they do urinate so watch out). Remember, wildlife carry diseases dangerous to people so get informed before working. For some information click http://icwdm.org  

Respiratory protection should also be worn while working in the attic. Consult relevant professionals before wearing one.
