A better mousetrap?

Apologies to regular readers, if there are any left, for my long absence. This is due to several factors including severe computer problems, poor signal strength, a shortage of suitable subjects and a general lack of enthusiasm.
Anyway, the up-to-date news is that we have acquired a rodent. We're in Suva, the capital of Fiji (whence we came in order to pick up bits for our non-functioning refrigeration system), quite close to the commercial port, and we think our unwelcome visitor swam out to us. We think it's a rat rather than a mouse but we're not sure. either way it's a nightmare. Filthy dirty smelly creatures (their urine is particularly dangerous) but worst of all is their need to gnaw - in common with all rodents their incisor teeth grow constantly and need to be ground down by gnawing. This is irritating on a farm, nasty in a house, but on a boat it can be devastating especially if they start on the electrical wiring for which they seem to have a special liking. Boat wiring is extremely complicated, and much of it built in and thus impossible of access. Tracing and repairing rat damage can take weeks and cost a small fortune.
 
Hence the search for a better mousetrap. Unfortunately moustraps have been largely superceeded by poison bait - less than ideal on a boat because you will probably end up with a rotting corpse in some totally inaccessible spot. Also available now are glue traps, made in New York:
 
 
This is a plastic plate about 0.3m diameter covered with very sticky glue in the centre of which you put your tasty morsel of bait - in the example above a square of valuable dark chocolate. Our rat has so far got entangled in these traps twice and on both occasions has got free, once at the cost of some fur. Now he won't go near them at all, but of course we have touched them and trodden in them. A fine mess ensues. Perhaps this idea joins the long list of failed improvements to the traditional mousetrap.
 
And here is the traditional trap:
 
On the left is a mousetrap, baited with cheese. Our rat has twice removed the bait without springing the trap. On the right is a (larger) traditional rat trap, again baited with cheese. This has a hair trigger - so the rat has left them alone entirely; this is one clever rat. In use one has to channel the rat towards the trap using walls, both fixed and arranged. But so far to no avail.
 
We are now using poison, seen as the blue lumps in the upper photo. Our rat has nibbled one, but not enough for a fatal dose, and certainly not enough to stop him discovering our vegetables which we had thought secure, and eating or rendering unusable the whole lot. But rather that than the wiring.
 
We are being driven mad by this rat; it really is a quite horrible experience.
