Eliminating cockroaches in my greenhouse!!

[vmax3000]

I hate them with a passion. I sort of transform into a swearing, crazed shoe-wielding maniac when I find them in the house. My husband fears for any decorative porcelain.... As of late, I have been overwhelmed by the population growing in my greenhouse. I have a toad and a lizard as rent free residents (or maybe I am the interloper!?!?) and the various unidentified spiders "hanging" around, so I really would prefer to find some method of knocking the roach population back without risking my health or the health of the other creatures. Any ideas? Are my standards too high? Thank you for any creative or funny comments, as well as experience!
Yours,
