Re: Refreshing trap
I don't think people give lures enough credit.
They last a lot longer than you would think.
If I have a dirt hole, I bait and/or lure it.
That should be good for a while unless you get a lot of rain. This is definitly the case with urine. After a good rain, I might add urine.
During the winter, I use a louder lure and bait and don't rebait or lure very often.
I talked with a guy who had traps out at the beginning of the season, pulled them after a few weeks, and this weekend found several spots that were dug up and worked hard. That's about a month and a half and we had some days of heavy rain.
Animals have great noses.
Make your set solid, in a good location, and your lure and bait should be good for a while.
I have rebaited and lured after a week or so, but I don't think its really necessary.
