Hobo spiders eat primarily insects, such as ants, flies, mosquitoes, moths, and cockroaches. Occasionally, they will also eat other arachnids and spiders, but that will only happen if they have no other food. Sometimes, they’ll also eat human waste.
Hobo spiders hunt using funnel webs. These webs have a silk line that will alert the hobo spider when another animal gets caught inside the web.
Hobo spiders have powerful venom, which they use to paralyze any prey caught in their web.
