Spiders are naturally attracted to areas where preys are abundant, insects are primary source of spider prey. So you must create proper environment for insects in your home, lights to attract nocturnal insects, flowers to attract butterflies and moths are attracted towards decaying vegetation(It may make your place smelly). Once insects are abundant then spiders are attracted towards these areas. Some parasitic wasps are predator to spiders like those belonging to Ichneumonidae, try to avoid these species. Also you can collect spider eggs and place it inside your home, so they will hatch out in your place.Some times you can see web full of spider nymphs, take it out and place it in your home.
Attracting spider to home can be achieved through buying some spider traps like poison free spider glue, which contains pheromones. Spiders are attracted to it and they will stick on them and eventually die, so you need to be careful and use the phenomenal effect of the spider trap to attract spiders or it will be dead and become useless.
The analysis revealed that the wasp spider pheromone is methylcitric acid trimethyl ester, a derivative of citric acid.
Some other techniques to attract spiders
An unspecified Cheiracanthium species is attracted to the smell of petroleum and has caused problems by weaving webs inside the canister vent of particular models of Mazda vehicles, resulting in blockages and build-up of pressure that could potentially cause fuel leakage from the fuel tank and an increased risk of fire. Mazda issued a voluntary recall of Mazda 6 models built between 2010-2012, to fit them with software which would alert drivers if problems were developing.

A spider that preys on the malaria-carrying mosquito is attracted to the odour of people's smelly socks, say scientists.

Eugenol baited traps we found seven individuals of two species of Thomisidae. In contrast, with the control traps, no Thomisidae were caught . Since Thomisidae were caught only in traps baitedwith eugenol, whereas no crab spiders were attracted to control traps, we postulate that eugenol served as an attractant for these spiders.
