Damage Prevention and Control Methods

Exclusion

Armadillos have the ability to climb and burrow. Fencing or barriers, however, may exclude armadillos under certain conditions. A fence slanted outward at a 40o angle, with a portion buried, can be effective. The cost of exclusion should be compared to other forms of control and the value of the resources being protected.

Cultural Methods

Armadillos prefer to have their burrows in areas that have cover, so the removal of brush or other such cover will discourage them from becoming established.

Repellents

None are currently registered or known to be effective.

Toxicants

None are currently registered.

Fumigants

None are currently registered.

Trapping

Figure 3. Cage traps for armadillos are more effective when “wings” are added to direct the armadillo into the trap.

Armadillos can be captured in 10 x 12 x 32-inch (25 x 30.5 x 81-cm) live or box traps, such as Havahart, Tomahawk, or homemade types. The best locations to set traps are along pathways to armadillo burrows and along fences or other barriers where the animals may travel.

The best trap is the type that can be opened at both ends. Its effectiveness can be enhanced by using “wings” of 1 x 4-inch (2.5 x 10-cm) or 1 x 6-inch (2.5 x 15-cm) boards about 6 feet (1.8 m) long to funnel the target animal into the trap (Fig. 3). This set does not need baiting. If bait is desired, use overripe or spoiled fruit. Other suggested baits are fetid meats or mealworms.

Other traps that may be used are leghold (No. 1 or 2) or size 220 Conibear® traps. These traps should be placed at the entrance of a burrow to improve selectivity. Care should be taken when placing leghold traps to avoid areas used by nontarget animals.

Shooting

Shooting is an effective and selective method. The best time to shoot is during twilight hours or at night by spotlight when armadillos are active. A shotgun (No. 4 to BB-size shot) or rifle (.22 or other small caliber) can be used. Good judgment must be used in determining where it is safe to shoot. Check local laws and ordinances before using shooting as a control method.

Other Methods

Since most of the damage armadillos cause is a result of their rooting for insects and other invertebrates in the soil, soil insecticides may be used to remove this food source and make areas less attractive to armadillos.

Summary of Damage Prevention and Control Methods

Exclusion

Fences or barriers are generally not practical, but a possible option.

Cultural Methods

Clear brush and other cover to reduce available habitat.

Repellents

None are registered.

Toxicants

None are registered.

Fumigants

None are registered.

Trapping

Live traps (box traps). Leg hold traps (size No. 1 or 2). Conibear® 220.

Shooting

One of the most commonly used methods.

Other Methods

Soil insecticides that remove food sources will discourage armadillos from feeding in an area.
