Spiders
To reduce infestations from spiders, use a waterproof silicone caulking to seal cracks and crevices along the foundation of the house, repair or replace damaged window screens, seal under outside doorways, remove wood piles, clean basements and closets, seal boxes, and eliminate clutter to reduce habitats for spiders.
Be very careful in those areas where black widow, brown recluse or hobo spiders are known to live. Seek immediate medical attention if bitten by these spiders.
