I recently answered a call for help from a lady who wanted a pair of rabbits removed from her garden.
On inspecting the place I found that my options were limited. There were one or two locations I could take a reasonably safe shot with my silenced .22, but there were too many houses and people around to feel comfortable using, or being seen with, a rifle.
This got me thinking about various options, and I decided I should at least take the opportunity make a couple of rabbit gums.
I made mine from some 8" x 1" lumber I had used as concrete boxing. It was pretty rough, but these traps aren't dining room furniture.
In my opinion there is nothing too critical about the dimensions. I figure that it has to be long enough so that the rabbit is completely inside the trap before reaching the trigger stick.... and that the tunnel has to be narrow enough to ensure that the animal has to push past the trigger. And it has to be big enough to allow easy access by the animal.
Some similar traps I've seen pictures of seem to have special guide rails or grooves for the sliding door. That wouldn't hurt, but I don't think it is always necessary. I figure the old timers who used hollow logs were unlikely to have fitted fancy door tracks. It would take a heck of a bunny to push the door open on my traps.
The trap has to sit reasonably level to ensure that the door drops cleanly... otherwise it could possibly jam on the rough timber walls.
So far I've caught nothing in my gums. The rabbits might be curious enough to enter the traps, or maybe to investigate them as a sheltered place to hang out. But I can't see why they'd go sniffing near foreign objects looking for food right now when there is an abundance of natural feed around. It has been a good exercise though. And I've finally got permission to set some snares, and I know from experience that I should see some results from these.
I left the gums open for a week or so in position. I've just started to set and bait them. I used carrots and carraway seeds for bait.
Best wishes from New Zealand.... Coote.
