This article primarily deals with my specialty, which is rats in buildings
, and inside houses - in the attic, walls, crawlspace, etc. But I do address general
outdoor rat prevention tips as well. I should warn you up front that it's not a quick and easy task. There is no quick-n-easy rat repellent
product or rat prevention
device that will get
the job done for you. If at any time you think you may need professional assistance, click in my map of hundreds of Professional Rat Removal Companies
throughout the USA. But read the below for education, tips, and
The most important concept in rat prevention is to eliminate the things on your property that attract rats. Namely, food and shelter. The first one is
obvious - don't leave out garbage that rats can access, pick up fallen fruit from fruit trees, do not leave pet food outside, etc. But I must warn you - even with a sparkling clean
property with seemingly no food at all, there may still be rats roaming about outside. And really, that's not a big deal. The thing is, you don't want those
rodents getting into your house. Rats can cause considerable damage
once inside a house or attic.
So you must eliminate the shelter, namely your home. The way you do that is to find out how the rats are getting in
building in the first place. This requires a very careful and detailed inspection of the entire structure, ground to roof peak. A knowledge of rodent behavior, and
they types of common entryways, helps. Rooflines, eaves, vents, siding gaps, electrical line entrance, plumbing, there are so many areas rats can use to gain
access into the home. But the good news is that yes, 100% of these areas can be found and sealed shut with steel.
Below is a good example of a repair to keep rats out of the house. They were living in the attic
and walls of the house.
They were climbing down the electrical line to the power supply for the oven, for which a small hole is cut in the wall. Rodents can smell the air coming through
on the other side, and a kitchen has scent of food, so they gnaw through the drywall, as you can see. I installed a metal plate so that no rats could get into
the kitchen again. But of course, that's solving only part of the problem.
Once you have inside areas like that sealed, the more important thing is to repair the outside areas that let them in the building in the first place. Then and only
then, you need to trap the rats. To do so before the building is sealed is a waste of time. Please read my rat trapping
guide, which will tell you the best ways how to get rid of rats
. You do ultimately have to
, but when you do, make sure it's done in a humane, and most of all EFFECTIVE manner. Never use shoddy techniques,
After the rats are all gone and no more can get in, doing a cleanup job is actually a very important part of the prevention process. Rats leave behind a strong scent with their
fur grease, urine, and droppings. You need to vacuum up all the rat feces
, and fog the attic with a special enzyme cleaner that
destroys the urine and pheromone scent from their fur oil. If future rats detect this scent, they'll try hard to gnaw their way into your house or attic.
Finally, I want to say that in regard to professional rat removal
, if you decide to hire a company, absolutely DO NOT hire
a traditional pest control
company. They don't do any preventative work. They want to sign you up for a never-ending
monthly maintenance package, so they just set a few traps at the attic hatch, spread some poison around (and poison is a HORRIBLE idea - it doesn't solve the problem and
just results in dead stinking rats in your house) and they never seal the openings.
Now for some common rat prevention tips and methods:
Rat prevention in the attic - as with any area, deny them access to the building by repairing any openings bigger than a half-inch! In fact, just seal them all no matter what
the size - it'll keep out bugs as well.
Rat prevention in the barn - a barn is a lot harder, because it's a bigger, open structure, with animal food. Your best bet is to keep the barn as clean as possible.
Rat prevention in the compost - try to contain it or isolate it, otherwise
the rodents will come and have a field day.
Rat prevention in the garage - just make sure the door is shut at night, and that it shuts tightly. Check the corners of the garage door for openings, and if you need to
install a new rubber strip, do so.
Rat prevention in the garden - this is a tough case. There is no good rat repellent device like a noise maker, sound machine, or anything that'll just keep them away. A cat is
actually the best prevention for an outdoor area like this.
Rat prevention in the house or home - as stated, it doesn't even matter if things are clean, so long as the home is sealed shut.
Rat prevention in the kitchen or restaurant - same thing. The only real thing that matters is a lack of open access holes into the building in the first place. If that's an impossible task for you,
hire one of my pros, or check the areas behind the oven and fridge, anywhere there are openings from the walls into the kitchen space.
Rat prevention in the yard - no dice here. Rodents live outside. The best you can do is to keep things as clean and debris-free as possible. And a cat does actually help here.
Customer Rat Email:
I noticed some 3-4 rats in my back yard. They were Never THERE before until i started throwing stale bread out for the birds. Needless to say,
I stopped throwing bread out now. I have 3 snap traps and caught 3 rats, but i still see a few each night. There is NO garbage or food around the house. I was told by a friend that
if i keep loading the traps with meat for the bait, which works great, that OTHER rats are going to smell the meat and come around, PLUS, he said he read where rats can communicate
with each other and their other rat friends where the food is, (in the traps) and others will come around. Now
I'm really confused. Do i still bait the traps, and try to catch more
rats, even though other rats can smell the meat where more rats could possibly come around, or do i just leave them alone and
hopefully they will leave if there is no food in the area
anymore. Is there anything I can do to prevent these rats from coming? Thanks
It's possible that there were always rats prior to the stale bread. If you stopped the bread, and they're still there, then the environment has adequate resources.
Trapping rats outside is kind of a losing battle. They will just keep coming and coming. I don't think that the traps will necessarily attract new rats, but it is true that rat
activity does seem to just cause more rats to come. Maybe you should stop trapping
altogether. If the rats aren't coming into your house, then maybe that's blessing enough, and
you can't worry about the presence of rats running around outside. No way to prevent that.
