Short answer: In Arizona and southern Nevada, rattlesnakes are most active in spring and again in fall. In the hottest part of summer they move mostly at night. They're least active in winter, which is the best time to install snake fencing.
Through the year
| Season | What snakes are doing | What to do |
|---|---|---|
| Winter | Mostly inactive, sheltering | Install or repair snake fencing |
| Spring | Coming out, hunting, most visible | Check gates and yard daily |
| Summer | Active at dusk and night | Use a flashlight after dark |
| Fall | Active again before winter | Keep the yard clear |
Making your yard less inviting
- Clear brush, wood and rock piles near the house
- Fix leaks and remove standing water
- Keep rodents down: they're what draws snakes in
- Close gaps under gates and drain holes in block walls
See a rattlesnake in your yard? Keep people and pets back and call a snake removal service. Don't try to move it yourself.
