I recently moved last month and ever since I've moved in we have been attacked by very large spiders. My 3 pigs and I live downstairs where all the spiders are, I've tried everything natural from peppermint oil to vinegar but nothing has worked. The spiders are only downstairs. My parents are calling exterminaters tomorrow and my piggies will be staying over at a friend's until it is safe. How long should I wait to bring the pigs back inside?? We are only spraying downstairs.
