Round-Tailed Ground Squirrels in Arizona: Control Options

Question: AZ desert, 3 acres. "Cute" ground squirrels now aggressive, entering fenced yard. Holes everywhere. Aviary attracting them. Want distance, not death. Repellent pellets/sprays for cats/dogs work?

Answer: Repellents Don't Work—Trapping or Exclusion

First: Confirm Species

You suspect Round-Tailed Ground Squirrels. See control guide.

Legal Check

• AZ Game & Fish: azgfd.gov | 602-942-3000
• Lethal control legality varies

Effective Methods

• Exclusion: Hardware cloth fence (¼″ mesh), buried 12″, 24″+ high
• Trapping: Check laws; euthanize per regulations (relocation inhumane)
• Habitat modification: Remove aviary spill food, reduce cover

Why Not Repellents?

Cat/dog repellents, ultrasonic, scent products—no evidence for ground squirrels.
