Air Conditioning ducts, particularly of those with Central Air.
Get some catfish bait, a few pounds of shrimp, fart bombs, or even a few dead squirrels - all of these worked well for me in High School.
Squirrels are probably by far the best and I recommend combining them with another form of attack. Place a few pounds of shrimp in one location and throw some frozen squirrels elsewhere.
About the time the shrimp smell really gets bad (about 2 days) the squirrels will be thawed and start to rot themselves. You'll get a nice delayed attack about a week after they find the shrimp.
