If you see a Gila Monster (Heloderma suspectum) in your yard avoid it – it may just be passing through. Do not get too close, try to pick it up, or otherwise handle it.
While the lizard is venomous, it is typically not aggressive and will try to avoid humans. Very few people are bitten by Gila Monsters. Since the 1940s there has been no recorded death from a Gila Monster bite in Arizona.
To have a Gila Monster removed:
Pima County (Unincorporated parts) — Call Rural/Metro Fire Department: Telephone: (520) 624-9913.
Tucson — There is no agency that removes Gila monsters for free. You must call private companies that charge about $75 to remove the Gila monster.
Options include: Desert Wildlife Services: Telephone: (520) 743-1411 and Animal Experts Trapping and Rescue Service: Telephone: (520) 531-1020.
