I have heard mothballs aren't very effective, kinda brought this thread here from my MG forum, one member said he puts dog hair in various places throughout the car & it works great, others were peppermint oil, cinnamon oil, & castor bean oil...
My father cuts up a bar of "Irish spring" soap into chunks & puts them in his Corvette over the winter, & has never had any problems.
I am NOT saying that ANY of these actually work, just what some people do...
I prefer the common sense approach, cover & plug any places they can get in, i.e. exhaust pipe, heater air inlet, air cleaner, ect, ect.
Then try to feed them a steady diet of poison & traps.
Also the garage itself, steel wool in cracks & holes does work, (unless they chew a bigger hole around it).
As far as my progress goes, it appears the chipmunk chewed at the rubber in the corner of the garage door to get out yesterday, (where I have the trap in the pic). Placed the trap there last night & sprayed critter repellent on the outside of the door.
This morning the nuts were gone, & had a mouse in the trap. So add critter repellent to the doesn't work file.
Going back to good 'ol peanut butter & traps tonight, & fixing the garage door rubber.
LOVE the carbon monoxide idea by the way, just don't get caught in your own trap!
Oh, I cant stand the chipmunks...yeah, they are cute but so destructive to both house and cars. We have zillions of the industrious little buggers!!!!
Last winters successful attack was to start up a couple of the cars in the closed garage and let them run for a half hour. Left the garage door closed for the day. The CO gave them a long sleep.
Come spring, lots of desiccated rodents but no damage to anything.
Now... how to keep them out of the shed and the covered boat over the winter...I am thinking mothballs.
Then how to keep them from digging out the edges of the deck and under pretty much all of my masonry.
I need a non-poison type solution as I let the dog have complete run of the place, plus she is effective at chasing any squirrels at ground level.
I would get a cat, but the wife has nixed this solution...plus they have a short half-life outdoors here as they are coyote food. There are no outdoor cats in the area.
