    Are there more rats around at particular times of the year? Are there any seasonal differences I should consider when trapping at home?

    Peak time for rats (ratus ratus -the bush rat) in this area (Hapuakohe Hills – on the western edge of the Hauraki Plains) is between February and June. This year we have gone through 6 kilo of rat baits and the three DOC 200 traps have also done their share. Now (June 23rd) I still have everything set and baited but there is little activity at all and so I just check every two weeks of so. Don’t find anything empty just nibbled – probably mice. The DOC 200 catch hedgehogs as well – they come when baited with an egg-which tells you something! Just wish I had neighbours who were keen but they are not.

    There definitely seem to be more rats in our traps in Polhill (urban Wellington reserve). A few people have caught pregnant females which is a little unusual at this time of year.

    I’m Lower Northland in the Kaipara. Went through a few kilos of rat/mice bait in just a few weeks in May . They seemed to peak and then fall away when it got cooler. No activity now. I guess they will appear again around September when it gets warmer..

    I got a bush rat in one of the DOC 200traps last night- the first in a while. Not much bait going at the moment. I think it’s important to keep the bait up to them as by trapping an baiting we create I believe something of a vacuum so that there are always ready to move in. Every rat killed now is one less to breed. What I can’t seem to trap are cats -wild cats are plentiful around here – mostly dumped.

    Had one rat brought in by the cat yesterday. But noticed the bait still hasn’t gone from the usual place so still not as many around at the moment.

    I am just looking at a graph of predators we trapped at a local 50 acre community Park – I started in July 2014 with bait for both possums and rats – after about 8 large buckets of Ditrac rat bait on a 50m*100m grid we realised they were laughing at us as they laid their coloured calling cards inside our Sentinel Possum traps while they ate the GN possum paste. So in February 2015 we changed to Contrac rat bait and invested in 50 rat traps – we kept on feeding them possum paste in the rat traps – by August 2015 we had trapped 250 rats and they stopped coming for a feed in the bait stations and the traps. It is difficult to understand rats and their need to visit a bait station or a trap as there may be other abundant supplies of natural foods in the environment – when that runs out they may visit you.
    IMO – it is essential to operate traps and bait stations at the same time and preferably at the same site – they can become either trap shy, bait shy or both following a bad experience. I have never had the luxury of surveillance cameras around traps but friends who do have such, have shown me some amazing film of rats crawling all over traps without getting near the dangerous end.
