An interesting, somewhat related, side note is that rodents like to eat things other than “food”. We have an off-grid cabin in Howe Sound and battling mice is an ongoing issue for us and everyone else in our cottage community. We had pretty much sealed all the mouse entrances and learned the best way to store our various foodstuffs in rodent-proof containers.
We thought we had the problem licked for a couple of years and then, in the spring of 2018, we opened up the cabin to find that the mice had been having a party all winter. There was mouse crap everywhere. We discovered that the roll of TP in the bathroom had been shredded but it wasn’t until we opened the cupboard were we store our candles that we discovered the real food source. The mice had devoured over 300 Ikea tea lights. We had never had this problem before. What we discovered was that Ikea had changed their supplier of tea-lights. The old ones were paraffin was while the latest ones we bought were paraffin/soy wax. The mice apparently enjoyed the paraffin/soy candles to the extent that the only trace of the original candles were the wick bases and the aluminum cans. In exchange, they left us a mountain of mouse poo.
A lot of insulation on electrical wire is soy-based these days. There are lots of stories of people who have experienced thousands of dollars of damage to their newer cars because rodents ate the wiring.
We also learned that the mice like to eat certain type of soap bars. Irish Spring soap isreportedly supposed to repel mice. Someone neglected to tell the mice because, when we tried putting chunks of Irish Spring soap near suspected mouse holes, it was pushed out of the way and partially eaten.
Another thing we learned is that the best mouse trap is still the conventional ‘instant-death’ spring traps that you can get at the dollar store for cheap with a light smear of peanut butter on the trigger.
We now keep all of our soap and candles, regardless of type or source, in large glass jars and store all of our partially used candles before we leave. We keep all of our paper products in plastic storage bins in a, so far, mouse-proof cupboard. We didn’t have much in the way of mouse “evidence” when we opened the cottage this spring.
Hopefully the hackspace will not suffer a mouse or rat infestation. In our experience, once they find a food source, they tell all of their friends and relatives. It becomes a huge problem to resolve and they continue to come back after the food source is removed just to scout around.
