Kill spiders by spraying hair spray on them. Any kind will do; aerosol or the pump spray kind. We have all kinds of weird bugs in Houston, Texas, USA and including spiders we know as "jumping spiders" because they really do jump. They're small and spotted black and white.
Hair spray will kill any spider. An exterminator told me it kills them by smothering them. Also, rubbing alcohol will kill them too - I read that on this site. Works like a charm. Hope this works for you!

Hairspray will immobilize the insect by coating its wings, so you can safely kill it. This is a page about using hairspray to kill insects.
