Identification
| Trait | Detail |
|---|---|
| Size | Leg span can appear large; body length moderate among house spiders. |
| Colour | Brown with varied chevron patterns on abdomen—subtle overlap with giant house spider. |
| Web | Funnel-shaped retreat at ground level, often in window wells, garages, and along foundations. |
| Eyes | Eye arrangement matters for experts; field ID to species is unreliable for laypeople. |
| Range | PNW discussions include hobo and similar Eratigena species; not every brown funnel spider is certified “hobo” without expert ID. |
| Speed | Very fast when disturbed—can startle homeowners. |
Public conversations about hobo spiders often mix them with giant house spiders and other brown funnel weavers. In Greater Vancouver, ground-level webs in garages and window wells are common. Accurate species ID frequently needs an arachnologist or experienced technician—yet safety and comfort still matter for families.
Behaviour & Habits
They build funnel webs with a retreat tube and wait for prey to stumble on outer sheet silk. They run quickly when prodded. They are not jumping spiders and do not make aerial orb webs. Seasonal activity peaks in warmer months; indoor garages can host them year-round.
Health & Property Risks
⚠ Health risk — professional removal recommended. Bite necrosis claims are debated in medical literature; any wound that worsens deserves clinical evaluation—do not self-diagnose from internet photos.
Primary home issues are fear, webs at entryways, and rapid movement that causes accidents—not structural damage.
Prevention
- Seal lower foundation gaps and garage door thresholds.
- Reduce cardboard and debris along walls where funnels attach.
- Pull beds a few inches from walls in ground-floor rooms if webs are nearby.
- Use monitoring traps along walls to gauge activity—not as sole control.
- Shake shoes and gloves left in garages.
How We Treat Hobo Spiders
We remove funnel webs, treat cracks and voids per label where activity repeats, and set monitors to track trends. We avoid sensational bite claims; medical questions go to clinicians. Follow-up compares web rebuild rates.
