Smiles I just wanted to add - are you sure they are actually huntsmen...in my experience the hunties are the ceiling dwellers, and it tends to be nastier species like black spiders and white-tails that dash about on the floor. I had our last house sprayed twice because it was totally infested - I was finding 1-3 spiders a DAY - many of which were in places like - on a towel you're about to use, in the piece of clothing you just picked up. Ugh. And they were actually poisonous species (incl lots of redbacks) - the doctor had a poster in their office of the ones to watch out for. So make sure you know what species you're finding...it might help to ask someone with local knowledge.
