Most spiders will only bite humans in self-defense
It is very difficult to achieve a long term eradication. Spiders are generally less vulnerable to insecticides than other insects.
Treatment by pest control professionals will help, but new spiders will sometimes move into the area where the original spiders were removed.
Be cautious of spider webs and wear gloves when working in the garden, around wood piles etc. Exercise care when handling cardboard boxes (some spiders may inhabit the space under folded cardboard flaps)
Most arachnids are nocturnal. During the day they are rarely seen, unless they are disturbed in their natural environments. When the light fades, spiders become active — leaving the protection of the shelters or burrows in search for food.
Spiders are air-breathing chelicerate arthropods that have eight legs, chelicerae modified into fangs that inject venom to kill prey and for defence, four pairs of eyes, two body segments (head is fused with thorax and abdomen) with jointed limbs (all covered in a cuticle made of chitin and proteins).At the end of the abdomen there are spinnerets which are used to spin silk
Most spiders that hunt actively, rather than relying on webs, have dense tufts of fine hairs between the paired claws at the tips of their legs. These tufts consist of bristles whose ends are split into as many as 1,000 branches, and enable spiders with scopulae to walk up vertical glass and upside down on ceilings.

Spiders can commonly found around windows, eaves, fence lines, bin areas, in leaf litter, under rocks, gardens, outside furniture, pool areas etc. Many dig burrows in the soil, while others spin distinct webs amongst vegetation.
Most spiders live for only one to two years, although some can live for over 20 years.
Females lay up to 3,000 eggs in one or more silk egg sacs
