Spiders are treated in a similar way to ants, however the areas that need to be treated/sprayed are more specific and isolated. Gutters must be treated, as well as any webs and crevices in which spiders may be living.
The spraying and treating of surfaces (wall, floors, roofs) does not ensure that spiders that travel across them will die. This is primarily because the substance does not penetrate into the spider's system and therefore does not harm them. Thus, one of the only sure ways to remove spider infestations is via physical impact.

1. Wear gloves when gardening or handling soil and rubbish.
2. Wear sensible foot wear outside particularly at night when most ground dwelling spiders are active.
3. Where digging or gardening has occurred nearby be alert for disturbed ground-dwelling spiders.
4. Don't leave toys or clothes on the ground over night as spider may use them as a temporary rest site.
5. Be alert for wandering ground dwelling spiders after long periods of very wet weather.
6. Be alert for wandering ground dwelling spiders following the widespread application of insecticides.
