How To Catch A Flying Squirrel: A Professional Guide To Humane Live Trapping

Catching a flying squirrel (Glaucomys volans or Glaucomys sabrinus) requires a combination of nocturnal behavioral analysis and the deployment of sensitive, small-mammal live-capture hardware. Success is achieved by identifying core nesting sites, selecting high-protein attractants, and securing traps along established arboreal travel corridors to minimize trap avoidance.

Strategic Preparation and Equipment Requirements

Flying squirrels are strictly nocturnal and highly social, often living in communal nests containing multiple individuals. Unlike larger rodents, they possess a high metabolic rate and thrive in vertical environments, necessitating a specific approach to equipment selection. Before initiating a capture, check local wildlife regulations, as specific permits may be required for trapping or relocating native wildlife in many jurisdictions.

• Essential Gear and Materials:

  
  
  
  • Live Traps: Multi-catch or single-door Havahart-style traps designed specifically for chipmunks or small squirrels.
  • High-Fat Attractants: A mixture of peanut butter, sunflower seeds, and rolled oats. High-fat content is essential to overcome their natural foraging preferences during colder months.
  • Mounting Hardware: Industrial zip ties, heavy-duty twine, or specialized tree-mount trap brackets.
  • Protective Equipment: Heavy-duty leather gloves (bite-resistant) and a thick canvas trap cover.
  • Monitoring Tools: A low-lumen red LED headlamp to observe behavior without startling the animals.

• Mandatory Standards and Benchmarks:

  
  
  
  • Trap Sensitivity: Trigger plates must be calibrated to a weight threshold of approximately 0.5 to 1.0 pounds to prevent premature discharge.
  • Inspection Frequency: Traps must be checked at least every 12 hours to prevent stress, dehydration, or potential predation on the captive.
  • Duration: The standard trapping window is typically 3 to 7 consecutive nights; if no activity is recorded by the seventh night, the trap location is likely inefficient.

Tactical Execution and Live-Trap Deployment

The key to capturing flying squirrels lies in exploiting their high-speed, vertical movement patterns. They rarely forage on the ground, preferring to traverse trees through canopy-to-canopy gliding.

Step 1: Identifying Nocturnal Activity Centers

Begin by identifying entry points into attics or walls. Look for "latrine" sites—accumulations of droppings—or small, irregular holes (approximately 1.5 to 2 inches in diameter) located near rooflines or gable vents. Use a digital trail camera with a black-flash infrared sensor to monitor these points for 48 hours to confirm the peak movement times.

Step 2: Selecting and Preparing the Trapping Station

Locate a branch or a horizontal structure that intersects the flight path of the squirrels. The trap must be placed on a flat, stable surface. If the surface is inclined, use shims to level the trap, ensuring the trigger mechanism operates under gravity-neutral conditions.

Warning: Never place a trap in direct, unfiltered sunlight. If you must set traps during the day, they must be covered with light-blocking materials to prevent the squirrel from overheating or succumbing to extreme stress.

Step 3: Baiting and Sensitivity Calibration

Apply the bait behind the trigger plate, ensuring the scent is concentrated in the back of the trap. Use a small smear of peanut butter on the trigger plate itself to encourage the squirrel to step directly onto the release mechanism. Test the trigger tension manually with a long twig to ensure it snaps shut with minimal force.

Step 4: Securement and Camouflage

Cover the trap with natural materials such as pine needles, leaves, or thin plywood to mimic a natural tunnel. This reduces the animal’s wariness toward the metal structure. Secure the trap firmly to the mounting surface using zip ties; a trap that rattles or shifts when the squirrel enters will result in immediate retreat.

Step 5: Post-Capture Protocols

Once captured, cover the entire trap immediately with a thick cloth. This quiets the animal and prevents the release of alarm pheromones that may deter other squirrels from entering the area. Transport the animal in a well-ventilated container if relocation is required by law, ensuring the release site offers adequate vertical cover and a nearby water source.

Comparative Analysis of Trapping Methodologies

Troubleshooting Common Field Failures

• Root Cause: The Bait is Gone, but the Trap Never Tripped.
  
  
  • Actionable Fix: The sensitivity threshold is too high. Adjust the trigger mechanism or place a small piece of bait directly on the pan rather than behind it to force a downward strike.
• Root Cause: The Squirrel Ignores the Trap Entirely.
  
  
  • Actionable Fix: You are likely not on the primary travel route. Re-evaluate the location using a trail camera. Consider switching bait to a higher fat content, such as walnuts or pecans, to compete with local natural food sources.
• Root Cause: Trap is Found Tipped Over or Displaced.
  
  
  • Actionable Fix: Lack of physical security. Utilize heavy-duty mechanical fasteners or bungee cords to anchor the trap to the substrate. The trap must be immobile, or the animal will be spooked by the instability.
• Root Cause: Non-Target Animals (Mice/Birds) Triggering the Trap.
  
  
  • Actionable Fix: Modify the trap entrance with a smaller restriction grate that allows a squirrel’s girth to pass but blocks larger intruders, or elevate the trap 3 to 4 feet off the ground to avoid ground-level rodent interference.

Frequently Asked Questions

What is the best bait for flying squirrels?

The most effective attractants for flying squirrels are high-calorie, high-fat items that provide rapid energy. Peanut butter, unsalted walnuts, sunflower seeds, and dried fruit are considered the gold standard for baiting live traps in an urban or suburban environment.

Do I need to be concerned about diseases from flying squirrels?

While less common than with rats, flying squirrels can carry ectoparasites such as fleas or mites. Always wear gloves when handling a trap and wash your hands thoroughly after contact with the trap or the animal to mitigate health risks.

What should I do after I catch a flying squirrel?

If relocation is permitted, release the squirrel at least 5 to 10 miles away from your property in a forested area with a dense canopy. Ensure the release occurs at dusk to give the animal time to identify a new nesting site before the peak of the next night’s activity.

How can I stop them from coming back?

The only long-term solution is exclusion. Seal all potential entry points with 1/4-inch hardware cloth, steel wool, or heavy-duty metal flashing. Trimming tree branches so they are at least 8 to 10 feet away from the roofline will also break the bridge they use to access your home.

Are flying squirrels active year-round?

Yes, flying squirrels do not hibernate in the traditional sense, though they may enter states of torpor during extreme cold. They remain active throughout the winter, meaning trapping and exclusion efforts can be successful even during the coldest months of the year.
