Crickets are seasonal, and have "big years" and "little years." This is probably a one-time occurrence. Just buy yourself a lottery ticket and consider them free cat toys/supplements, and they'll go away by themselves. They don't live very long.

Reggie - I live in a basement and welcome the spiders too, because they eat the moths who would otherwise eat my clothes, and the fruit flies who get in my juice and make unwanted punctuation on my computer screen. I've even come to terms with the silly house centipedes, because they eat ant eggs, and I really don't want to deal with ants (so far they're doing a great job).

Love, Columbine
