Inventory and survey, as well as movement between habitats, can be observed by arranging traps in a linear pattern. Elliott traps are very useful for wildlife survey and can be arranged various ways. ![]() However, excluders can be used which stabilize the base of the trap and keep the bettong from reaching the bait. There have also been issues of burrowing bettongs setting off the traps. If animals are caught during the hot day, they are at risk of being “cooked” by the aluminium. The traps are checked in the mornings, and then closed. If using Elliott traps during hot weathers, the traps should remain open only at night. Elliott traps are effective for capturing small mammals, such as mice and rats. Just as in cage traps, pressure applied to a pedal on the floor activates the mechanism that closes the trap door. They are baited, usually with peanut butter at the back of the trap. They operate similarly to a cage trap however, they are enclosed. Sterilise trap before setting again to avoid spread of diseaseīelow is an instructional video on setting and using a specific brand of cage trapĮlliot traps are small aluminium box traps with a foot pedal.Stand behind trap and release by pulling the door mechanism.When captured, cover the trap to keep animal calm.Place bait in back of trap, on bait tray and in front of trap.Place on ground and camouflage trap with leaves, brush, twigs, etc.Set trap by activating spring mechanism (will vary based on specific trap).Apply insect repellent to prevent exposure to parasites.Wear protective clothing at all times when handling the trap (ie: long sleeves/pants, protective gloves, closed-toed shoes).Make sure trap is sterilised to avoid spread of disease to trapper and animals.Exposure to parasites (ie: fleas, ticks).Some animals difficult to handle (scratches, bites).Must be checked often (especially in extreme weather).Some animals (ie: feral cats) may injure themselves trying to escape.Non-targeted species may be caught in seasons where food sources are scarce.Easy and safe to release captured animals.Safer way to handle feral or rabid animals.They are often used for relocation by conservation departments, as well as for wildlife sampling and tagging. These traps are often used for larger animals than pitfall traps, such as foxes, possums or feral cats and dogs. Cage traps can be entered from one side or both, depending on the trap. ![]() The animal applies pressure to a tray on the floor of the trap, which sets off a spring-loaded mechanism, releasing the door over the trap entrance. Bait can be olfactory (urine, meat, animal droppings), visual (feathers, lures) or auditory (field attraction phonic device). It coaxes the animal into the trap using bait.
