Maybe.. but my kid killing it or spraying it with hairspray or Lysol is much cheaper... and I don't have to kill spiders that aren't in my own home or room., so don't have to worry about it in public.lol
Stamps, spiders eat bugs, like roaches and flies. I never kill spiders - just scoot them outside.
Your phobia has a name, arachnophobia. Derived from Arachne, the weaver Athena turned into a spider .
