I bought four of the plugin ones off Amazon. They specify the range they work and we get mice in our basement. I plugged them all in downstairs except one I put in my garage. Surprisingly they did work, even on spiders. This was two years ago I think, but a few months ago they stopped working. They may of stopped working sooner because a year ago two stray cats made a home of my garage and the deal was they can stay and I will feed them if they catch mice lol. Which they do lol.
For squirrels, place traps along the wall in the attic or crawlspace, near the bottom of the trees outside your home, and directly on your roof, especially near trees or power lines that may be routes that squirrels take into your home.[15]
Alternatively, you can also use cat’s litter. However, if the rat is infected with toxoplasmosis, it strangely may actually be attracted to cats and cat litter (a very weird side effect of the disease)
ANSWER: There is limited data on how well electronic or high-frequency sound devices work for household pest control. These devices may be called ultrasonic, electronic, microvibration or electromagnetic pest repellers. The manufacturers state that they use high-frequency sound waves or electromagnetic output to repel insects (cockroaches, fleas, house flies, mosquitoes, rodents, moles, and other pests).  There is truly no data, aside from anecdotal information on various internet sites, as to the effectiveness of these devices.

Consider kill traps. Electronic kill traps are widely considered to be the most effective method of removing mice and rats from your home. They are also safer for non-rodents in your home, and easier to dispose of compared to other kill traps. While they are more expensive, they are the quickest way to rid your home of mice and rats, and are the most humane type of kill trap. (Live traps, however, are the most effective way to get squirrels out of your home.[8])
After reading several reviews and deciding against the collateral damage that glue traps and poison could cause, as well as watching several videos on how to make various bucket traps, I decided the classic Victor M326 Professional Rat Trap would best suit my needs. What can one say … it’s an oldie but a goodie. I placed the order from Amazon and waited for Prime delivery. In the interim I watched and plotted. I watched that bold lil’ rat scurry from the outskirts of the yard across the center of the lawn, again. It cruised under my car, paused and checked to see the coast was clear, and then it gleefully jumped into the garden. No, I’m not crazy, the movement with which the rat entered the garden was gleeful, almost like it was prancing. It was out for a night on the town at our expense. I could do nothing but wait for the traps; however, el raton made one critical mistake – now I confirmed its entry point to the garden and knew it’s approximate feeding time, it was the second evening in a row it entered the garden at the same spot and same time out cruising for grub. I couldn’t wait to get that rat bastard.
If you have rats under your floorboards, then don’t panic! Having rats under floorboards stumps many people in finding the best way to get rid of them. This is why I have written about a number of ways you can make their lives very uncomfortable so that they leave you in peace.
Note: If you encounter an animal who’s stuck to a glue trap, pour a small amount of cooking oil or baby oil onto the stuck areas (avoiding the animal’s nose and mouth) and gently work the animal free. If you can’t free the animal, quickly rush him or her to a veterinarian or wildlife rehabilitator. Sometimes euthanasia performed by a veterinarian is the most humane way to end the trapped animal’s suffering.
We had mice in the kitchen and garage. I put one plug-in reller in the kitchen and two in the garage. After about a week, no more mice incidents at all. That was over a year ago. Now to tackle the backyard with more powerful models to see if that will be a success as well.
Designed for indoor use or anywhere it’s not exposed to outdoor elements, the reusable Victor Electronic Rat Trap provides years of effective rat control—perfect for attics, garages, basements, and sheds. The trap does not use any poisons or chemicals, but as with any electronic device, it should be used with caution around children and pets.
Drive a stick through the opposite ends of the water bottle (Or whatever object you chose to use. It should be cylindrical and easy to roll.) Drill holes in two sides of the bucket near the top where you can slide the hanger through. Fill the bucket with water. (optional) Set up your ramps, and then bait the rolling mechanism. You’ll have rats climbing up to get to the delicious bait only to be dropped to the bottom of the bucket!
We had field mice come in, bought a plug in repellant, we put poison down and got rid of them. We kept the repellant plugged in since this was 3years ago. Now, for the past few evenings we have heard noise in the loft. Thinking it could be a squirrel we went and had a look. Going by droppings could be a rat. No damage so far so put poison in, but wondering the plug in could be working. Also, it works through the electrics in your home. Hopefully sonic noise driving it crazy.
Size the barbwire so that it is exactly the shape and dimensions of the bottle’s opening and cut off the piece. Glue this piece of barbwire over the top opening of the bottle. In practice, the barbwire should replicate a swinging door.
to people who say diatomaceous earth works, you are lying. It does not work at all. I can’t believe there are so many people willing to keep that BS alive. I had fleas and spread it all over my house up to a quarter inch deep. Fleas just laughed at me. I used it because I did not want to use any chemicals as I have cats. I found something called fleabusters and (ortho-boriic acid) I was afraid it would hurt my furry friends but decided to give it a try after speaking with a few people who used it, so I took a big spoon with holes in it, scooped up some of the fleabusters powder and softly dropped the spoon every few inches to release a small amount of powder and spread it over the carpet. About 10′ by 10′. Then Took a plastic paint tarp, laid it over top of the powder and walked all over it. Vacuumed it up with my dyson animal and voila! fleas became history within a couple days. Cats were not affected and life returned to normal. Anyone who says diatomaceous earth works is trying to sell it to you.
I am a believer. I use a three stage approach: warfarin in baits outside and a combo of glue traps and a single Victor trap. After two days, I got my first one in the kitchen with the Victor. Placement is the key. If you see mouse poops, that is a good place along the wall in a dark corner. Disposal is easy and it never got soiled with the first mouse. But if I get another mouse kill, I will clean it out to be sure it is attractive with the peanut butter on the bait cup.
they where great my fault just a little too large could have done with a size just a little smaller not sure there is such a thing ? they just eat the bait without trap going off as you can see I am a novice thanks
I tested one by setting it up and triggering it with a stick. It broke after triggering 2 times. The 2nd one broke while I was pulling back the kill bar to set it up. The 3rd one almost broke while pulling back the kill bar, but I stopped pulling on it to avoid breaking it. It seems like the loop of the kill bar on the right would come off the horizontal bar easily, causing the spring to become dislodged. See the attached photos.

Leaving the phone plugged in and the app running all night. It has different frequencies to choose from, so I will change the frequency each night. That way the rodents won’t get used to any one frequency.

I grew up in the Midwest, and every so often little mice from a neighboring field would occasionally find their way into our home and set up shop. On one such occasion, we picked up a package of glue traps from the local hardware store and set them out around the house. Back then, I didn’t realize just how horrifying a little glue trap could be.
Snap traps are a humane choice when they are able to kill instantly. Ideally a snap trap is activated when food bait is removed or eaten by the rat, triggering the spring loaded mechanism. When the metal bar strikes the rat in the neck or spine, death is usually instantaneous. However, sometimes a rat will be caught by a paw or tail and not killed outright, resulting in an inhumane, prolonged death.
Affix a string to the bottle. With your bottle oriented so that the hinge is on the surface of the table, you should now have a bottle with two skewers through its upper part (one just to the left and one just to the right of the place you made the cut). Turn the bottle over so that the hinge is on the top. Unscrew the cap and place a string as long as the bottle approximately one inch down through the mouth. Screw the cap back on tightly with the string still partway inside. Give the string a slight pull to ensure it is snugly in place beneath the bottle cap.
