Having A spider infestation problem.?

So I awoke this morning with a spider bite on my neck,this is the fifth one in the past month......needless to say, im pissed. So iv got a quart or so of 30% strength ammonia at my disposal and the room I need to clear of spiders is quite small; id say 15 by 15 ft im thinkin if I set open container of this strong ammonia in the center of the room with all the windows and doors shut off I can finally rid this scum of the face of the planet.... Will this work?
