raining dead black widows
why would i be seeing black widows lying half dead on the sidewalks in public areas in Snowflake AZ?
Navajo County Arizona integrated pest management
Generally, a die-off of spiders is either due to pesticide exposure and/or significant change in the weather. Given that black widow spiders tend to be in dark, enclosed spaces, to see them in the open suggests pesticide exposure. Any photos you could provide would be helpful.
