SUMMARY: One last one, opening needs sealing
No activity on any traps from about 6:30 last night til half past midnight; one under the sink when I came down in the morning. So I'm pretty sure that they're coming in next to the pipe under the sink and I'll just have to block that off.
It has been such a challenge to keep the dogs away from the traps! Under the sink cabinet is not an issue, although they were very interested while I was putting them there. But the ones in my bedroom, despite being behind heavy furniture with things blocking access, you can't imagine how hard they tried to get around my blocks!
Of course, they also spent a lot of time yesterday sniffing around all kinds of interesting places as if there had been a lot of rodential activity and they were following the scents to see if anything exciting was afoot. In fact, a couple of times when I kicked or bumped something at floor-level abruptly while moving things, the dogs instantly pounced on whatever it was, so they had primed themselves for vermin.
I hope this excitement is over and I can go back to setting traps in my agility courses in the yard instead of the mousey kind.
