Using some bailing wire, I merely hang a picture of a "fulton" underneath the car. (Yes. Just a picture. (Sliding an actual "fulton" under the vehicle would be considered cruel and unusual punishment.)
While Decon, or some other poison, well placed along the permitter baseline of the garage's walls works pretty good in controlling population, it seems that the picture works even better. Those mice and rats have better taste than some people and, thus, avoid seeing something really gross no matter the mouth watering odors being emitted from the cars upholstery and wiring. Besides, the picture never needs replacing as bait does.
Seriously. After measures have been taken to rid yourself of those rats and mice, plugging holes in the car's body that give them access to the interior is further protection for those mice and rats who somehow miss seeing the picture.* It is said that any opening they can get their head through the rest of their body can follow.
Fleetliners don't have mice and rat problems. Any visiting or passersby rodents merely stop in their tracks and admiringly stare at the car for a spell, shake their heads and move on to someplace with a 37 or 38 to gnaw on. You know.
Best,
Charlie
* Using two pictures mounted back-to-back may be a temporary fix for this happenstance but as word gets around amongst in the rodent population, one will be quite enough. Then the extra picture can be sold to a 37 or 38er. You know.
BTW: Mounted "fultons" do not scare off rodents. As many other animals they tend to not look up very often. Especially way up there.
BTW2: It seems this topic comes up right often. Not as ofter as oil questions but still now and then. After my solution using a picture gets around we may never see posts about mice and rats again. Just saying.
BTW3: Once Tiny wanted to bait a mouse trap and couldn't find a piece of cheese so he used a picture of a piece of cheese instead. Next morning he went to the mousetrap and lo and behold there was a picture of a mouse where the picture of the piece of cheese had been. Mice are not only as smart as some humans but, can be, seemingly, right retaliatory humorous as well.
Sorry, Tiny. The devil made me do it.
