What we might learn if we keep our eyes open

Great to hear from you WFW – I have found that GN chocolate lure has not been as effective as other lures - today we have switched about 40 rat traps from GN possum paste to GN meat lovers – it will be interesting to see if there is any response. Rat numbers are low - today we found six traps tripped – but no victims – one had its coreflute cover ripped of the tree so maybe a large animal involved.
Great that your T Rex traps are working well for you - trap design and plastics evolve – they no doubt improve if they get reports of breakages or soft catches. A few years ago, I did a season on a line at Puketoki Reserve – they use walk through boxes with a central T Rex trap so animals enter the trap from either side. I had a chat to the Puketoki controller today and he tells me that traps rarely break, and wounded animals are few – so this matches your experience.
While working in the Park today, I met a lady who was having problems with rats on a lifestyle block – traps in a shed and under the house not killing rats – T Rex! – so she took a picture of the spare Kness Snap-E I carry in my pack.
The picture below is of a walk through box with a central Gorilla trap – difficult to place the trap while set and the last bump often tripped it – black nails so I dislike Gorillas intensely! The Trex is much easier to place and works well. Also a picture of the cover ripped off a trap today – I like open covers.
Let me know if I am boring people.

Keen to be involved. I’ve noticed too that one bait someone raves over in a bush block or farmland is useless in sub alpine so if the study could include type of landscape plus altitude please that would make it even more useful.

With a whole sachet of the chocolate and nut lures, I trapped maybe 10 rats. The Meat Lovers’ lure is one of my go-to lures, because I’ve had such good results with it.

Goodnature’s Cinnamon Possum lure has actually trapped a decent number of rats - I’d say its trapping rate is 5x better than the chocolate and nut lures, so it’s worth a try, IMO. I use it 3-4 times a year as a “curiosity lure”, to pique the interest of rats that might be bored with what’s normally on offer. I was surprised to find that it was a successful lure for a pair of weasels that I trapped within the same week in December.

It would be interesting to find out how the chocolate lure performs in habitats occupied by humans vs the wild. If rats have already eaten chocolate out of somebody’s garbage, I think that they are likely to develop a taste for it. Under those circumstances, the chocolate lure could be way more attractive to rats, mimicking a delicacy.

I prefer the T-Rex over other snap-traps for a number of reasons. I don’t only use the T-Rex, though, because I’ve had way better results since I started using a variety of traps. If I only used DOC tunnels or snap-traps, my rat kills would drop by about 50%. I think that the reason why using multiple models is effective (for me, at least), is that rats that become really good at eating the bait out of a T-Rex, might not be as good at eating out of a Kness/Gorilla, for example. If a rat’s able to eat the lures out of the T-Rex and Kness/Gorilla without getting killed, it might slip up when it encounters a Victor Pro.

Often when inexperienced trappers are having difficulty killing rats, the trap(s) aren’t to blame. Was the T-Rex in a tunnel or was it sitting on the ground? Was it sited properly? Was she using good lures? Was she checking the trap frequently?
Switching to a Kness won’t make any difference if she doesn’t learn to use her traps properly. Your advice should turn her T-Rex into a killing machine (if she didn’t get rid of it, that is).

I, too, have ended up with purple fingers for a while after accidentally setting traps off.
The T-Rex is the worst of the lot, because the teeth add skin injuries to the bruises. My fingers can definitely tell which trap is the strongest and has the best grip.

Recently, I ordered a pair of snap-trap double-sets for Gorilla traps. TR’s don’t work in the tunnels, unfortunately, but Kness and Gorilla traps are held in place.

DOC double-sets have much higher trapping rates than single-sets, so I’m interested to find out if snap-trap double-sets also perform better than single-sets.

The main reason why I bought them, is that there are some good sites that it would be difficult to get DOC double-sets to and I doubt that I would be able to get them to sit on the ground evenly, because there are a lot of rocks and exposed roots to deal with. The 365’s will go almost anywhere.

If you can find it, I highly recommend trying tallow in your traps. Just be careful using it, because some bird species are fans of the stuff.

You aren’t boring me! I wouldn’t reply to your posts if I wasn’t interested in what you have to write. The more that trappers communicate with each other, the better our collective results will be, in my opinion.

Knock 'em dead, Mindie!

Hi Dan. If you don’t like the idea of carrying a firearm around, even an air rifle, they can get heavy if you’re carrying them all day. I use a lance ( a 20cm stiletto blade attached to the end of a converted golf putter) it even doubles as a walking pole. It will dispatch any animal you live capture. I use a forked stick behind the shoulders or neck to hold the animal still while you say goodbye.

Cats, hedgehogs and rats – they all leave a trail behind them. Some have a large home range but its often worth putting out a cage or a trap. I had a few “neighborhood

” hogs around my 1-acre garden - a magpie trap worked well, and I cleaned out 20 in a few months. At least hogs are on the PFBOP hit list.
