Arachnid
House & Sac Spider
Cheiracanthium spp.
Most indoor spiders in Kempton Park homes are harmless and beneficial — they reduce cockroach and fly populations. The exception is the yellow sac spider (Cheiracanthium), responsible for the majority of medically relevant indoor spider bites in Gauteng. Targeted residual treatment plus harbourage reduction (cobweb removal) controls populations without removing the beneficial garden species.
How to identify
- Yellow sac spider: 8–10 mm pale yellow with green-tinged legs
- Hides in silk retreats in corners and behind pictures
- Active at night, moves quickly across walls
- Cobwebs in ceiling corners and outdoor light fittings
Where they hide
- Ceiling corners, behind framed pictures and curtains
- Behind toilets and inside cupboards
- Outdoor light fittings and window frames
- Garden sheds and garages
Health & property risks
- Sac spider bite: localised pain, redness, occasional necrosis
- Bites usually occur while sleeping
- Web build-up looks unkempt for guests and customers
- Webs around external lights attract more flying insects
Prevention tips
- Remove cobwebs monthly inside and out
- Reduce outdoor lighting that attracts flying prey
- Shake out clothes and bedding left on the floor
- Treat skirting and corners with residual insecticide
