I would be concerned about food poison combos for two reasons.
#1 is if I forget where I may have put it, my dogs will remember. Nuff said.
The second is if your mousey decides he likes his digs.. and he nibbles what he *thinks* is a nice meal, then uses your cubbie for a nice nap.. he will make his presence known quite shortly.
That smell is hard enuff to get out of full sized houses.. I can't imagine what it would be like to open a 13 footer with a nice smelly corpse in there.
Like Gerry, when hosting, I left unrefridgerateds in my trailer all summer where there are chipmunks (They can get into just about anywhere a mouse can) without incident. I kept food in sealed containers, or it already came that way (Cans etc) I did a look around for places they might get in and did not see any ready places.. there must have been none. I DID have a cat in there most weekends, however. Maybe his scent deterred them. (They aren't scared of dogs.. they would mock mine and steal their food
There is one place another critter can get in tho.. and those about to eat or with weak stomachs may want to stop reading here.
On my last weekend there, I went to use the whole reason I bought my trailer.. the bathroom. I have an inline valve on my waterline to the toilet because.. it's a good idea in general, and because I have a leaky ball valve on the toilet. With the lines pressurized at the bowl, my black tank fills quickly with clean water from the slow eeking down the flap.
Anyway.. this particular time, I forgot to turn the water on, and I "Dry" flushed. The bathroom quickly filled with buzzing and a giant black cloud
. Thousand of baby flies flew up the bowl flap opening and into the bathroom.
I must have gotten there just after they hatched, and before they figured out they could get up the vent pipe. Mamma, or Mamma(S) must have flown down into the pipe and found the perfect spot for their nursery.
I am astounded that they could thrive in there with all the chemicals I use.. but they can.
