The heat wave in Phoenix is prompting an early emergence of scorpions and rattlesnakes, raising concerns for residents and pet owners. Temperatures exceeding 100°F (38°C) have accelerated the activity of these venomous creatures, which typically peak between April and October. Heather Doss from the Arizona Poison and Drug Information Center (AZPDIC) highlights that critter activity is highly temperature-dependent. Data from AZPDIC indicates nearly 1,300 bite and sting cases last year, with scorpions accounting for 734 exposures. This year, Phoenix has already reported 10 rattlesnake bites and 237 scorpion stings.
