Household Vermin - How to deal with mice and rats getting into the home?

My skin is still crawling guys! I have had the unfortunate experience of having a rat run across the floor of my kitchen and it took five years off of my lifespan. I know it's an irrational response but I tell you, I screamed when it happened. Little goober managed to spook me pretty good.

I'm used to the occasional mouse, usually when the winter is settingin, getting into the house but this was a RAT.

How do you deal with the reality of vermin getting into the house? How do you approach the issue? Are there permaculture solutions out there to consider?

My approach currently involves trying to understand how we got to the point of a rat entering the house. Traps, to me, deal with having intruders in the house but I would like to simply prevent intruders from entering.

I'm lucky enough that where the rat scurried seems to make sense of being the entrance into the house. Mysterious plaster crumbs had accumulated in the area and I did not realize that a hole had been created. I have temporarily blocked this hole and, fingers crossed, there has be no rat sightings nor rat sign found.

I believe I need to take the time this weekend looking for potential entrances and flag them for repair.

I'm a little disappointed that my dogs have been of zero help with this sudden intrusion. You'd think these pampered pooches would at least try to defend their home. We are going to have to have a talk about their role in this household!

Always a concern in areas that have lots of Nature's critters running around.   Keeping food sources in check is #1 control.     Putting dry goods in glass is much more effective than plastic tubs.  The critters you are concerned with can chew right through plastic.

Keeping doors closed and sealing up around them with galvanized tin is a proven effective maneuver as well.   6" tall galvanized tin.   Aluminum is no good.

Bait blocks in the cellar and attic and under the counters, also in closets.  Best to keep this stuff away from your' pets but it is effective.   The critters eat the stuff and then go outside seeking water.  They will die.  

Sticky trap paper and old fashioned "large size" mouse traps!   mmm.... peanut butter.   lol...

Don't be surprised if you look up at your' soffit and fascia of the house and see a hole or two.  These gangsters will crawl up the downspout and find a spot to enter into the attic.

Personally, my best defense is a Dog.   Surprise!  no cats... one of my hound dogs is so completely devoted to home security that she will "end" anything not invited into the home.    Cats are a great idea too, I just don't keep any as pets.

Just in case you missed it...     Removing any food source is #1.
