Spider Control
Most household spiders are harmless and even helpful, but heavy webbing or venomous species like black widows and brown recluses are worth professional treatment. Control focuses on reducing the insects spiders feed on and sealing entry points.
Typical cost: $120 to $350

How to prevent them
- Reduce other insects (spiders' food source)
- Seal cracks and install door sweeps

Spiders are often most noticeable in late summer and fall as they mature and search for mates.
