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.

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.
