Understanding Spider Infestations

Spiders are often found in yards and homes due to two main reasons:

1. Floating Baby Spiders: After hatching, baby spiders can travel long distances by floating on air currents, potentially ending up in your home or yard. This makes complete eradication challenging.
2. “Your House Is Theirs” Principle: Spiders often establish their territory within your home, creating webs and laying eggs. This behavior makes them difficult to eliminate entirely.

Best Outdoor and Indoor Pesticides

Outdoor Pesticides:

• Look for products with long-term residual effects and strong sticking power. Cyfluthrin and Permethrin-based pesticides are effective for outdoor use and remain active for up to 90 days.

Indoor Pesticides:

• Choose low-odor, water-based products to avoid respiratory issues. Gentrol IGR is effective for preventing spider eggs from hatching and is ideal for indoor use.
