If you find the mouse trap bait is gone, but the trap did not snap, the trigger may not be sensitive enough.  Place a small amount of sticky or gooey mouse trap bait like peanut butter in the bait station.  Then push a nut or other tidbit in the middle of the peanut butter.  This forces the mouse to stop on the platform & apply more pressure to the trigger while removing the nut.  This method will prevent the mouse from just grabbing your mouse bait and running away to safety.  
I moved into my newly built home one year ago, I had some ants last year and lots of those black long bugs with the pinchers on the tail and a couple other types of bugs, had a mouse the first night I slept here. I bought a six pack of repellers at Costco and have them all plugged in one in garage and four of them in second floor.
I’m visiting Canmore, Alberta, Canada from the US and the Canadian Tire I was just in definitely sells 2 brands of ultrasonic rodent devices. So the gentleman that said they are banned in Canada is incorrect. Sept 6 2016

Set several traps per room. There are usually many more mice than you actually see. Rodents like to use the same paths over and over again. They also tend to stay close to walls where they feel more protected. Put the trap down at a right angle to the wall along the path they normally take, with the bait side up against the wall and directly in their path.
If you notice you have a mouse problem, do not just go out and buy the first available mouse trap. You need to evaluate several factors before deciding on mouse traps that are ideal for your particular situation. Here are some of the questions to consider:
If you see a rat in your home, then chances are there are more where that one came from. According to allbusiness.com, one female rat can bread at 2 months of age and can produce as many as 22 pups in one litter; and one female rat can have as many as six litters in one year. Rats present a number of problems to your home, most notably health issues—rats are known to carry disease. If you suspect a rat problem, consider using Tomcat rat traps. Armed with Tomcat traps, all you need to do is set them up.
From what I understand whatever you’re trying to repel gets use to the sound. The idea would be to get one that does random sounds at different frequencies so they don’t get use to the pattern. I’m not sure if there is a product that does this?
5) Are mice entry spots located in “sensitive” areas of the house? If the mice enter or frequent sensitive parts of the home, such as near expensive carpeting or upholstery, then you may not want to risk blood splatters using a Snap Trap. Equally though, there is a risk of mice rolling over Glue Traps onto those surfaces. An Electronic Trap or a Baiting Station might work best in such situations.
Actually, these rodents will eat just about anything. We were fortunate that we only lost a pack of cheap noodles and was left with only one extra opening in his pack. If left to their own survival instincts – they gotta eat – rats can destroy non-hardened food storage items and spread disease.
Maybe if you just put a thin line of pb around the can, they would have to reach further and spin off the can. That was one big rat. The ones that got into my house were about 10 inches, nose to tail.
I find a splash of Pine Sol to be helpful with dead critter stink. Don’t know if it will deter the buggers from coming to the bait, but it probably won’t, in itself, kill anything else that comes along. Bec is right, ethylene glycol is highly toxic . . . but attracts animals due to its sweet taste. Don’t wan’t to kill the birds and bees and dogs and deer . . . just the rats.
Can anything speak louder than a photo of a giant dead rat in this device? I don’t think so. I can’t believe it. I set it up Saturday afternoon… no luck that first night (might has been my bait choice and/or location), then moving to the edge of a wall facing the bush my cat caught one in and putting the bit of peanut butter on the wall of the back, and bam, this morning I look out and see the little feet hanging out the front entrance. Im an animal lover but after what I have been through..seeing that felt like christmas to me.
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.

A Live Cat – Yes, cats are great hunters, and will kill rats. But will they kill the rats in your attic and walls? Unfortunately not. I can’t tell you how many cases of rat infestation I’ve gone to in homes with pet cats. It happens every week for me. Same goes for dogs, of course, even good ratters like Jack Russell Terriers.

Eliminating rats from an office building or factory is a much larger mission than trapping rats infesting a home. If multiple floors are seeing signs of rats, you need to learn the root of the problem. They could be accessing these spaces via air vents, basements or even toilets. Once access points are identified, conquer these rodents with a sufficient number of traps.
1) Are you okay with having to dispose of the bloodied carcasses of dead mice? Snap mouse traps are highly effective, but they often leave a bloody mess. You need to physically unlock the dead mice and dispose of them. Then, you need to wash the equipment before reusing it again. It an effective way to deal with these little pests but it is not something that people with weak stomachs are able to deal with on a regular basis. There is a huge reason why it is a popular mouse trap, it gets the job done, it does it a little brutally but it definitely serves its purpose.
This is a domestic rat trap made from a ladle and a spoon. It is known as one of the best homemade traps. For a good result, you only require a huge bucket, a spoon and some bait such as peanut butter. By the way, you can make a peanut butter for rat bait yourself in less than 15 minutes. Just take peeled peanuts, roast them, add a tablespoon of vegetable oil and put this mix in a blender – done!
Q.I have had no luck so far with this trap and peanut butter. I’m thinking that the problem may be that the first time I handled the traps I wasn’t wearing gloves, so I left my scent on the traps and that’s scaring off the rats. How do I clean the traps to remove my scent? I read somewhere that I just need hot water, but is dish soap needed too?

There’s a field behind my house and we sometimes get mice inside during winter. This year I’m not so sure. We’ve heard noises in wall cavities for several weeks but have not caught a glimpse or found droppings. I think I know where they’re coming in and have blocked it. I put out 3 humane traps using peanut butter&chocolate but nothing taken. I can’t find any disturbance to food in cupboards or any packages of food left out. I’ve now put a few things down to see what they might take for bait. They have taken some nuts and a small chicken bone (I heard them drop it on the floor), but have not eaten the porridge oats. I usually see the mice and their droppings. Is it rats?

Peppermint Oil – Um, yeah. I’ve actually used peppermint as BAIT on rat traps, and caught rats! Sure, peppermint is going to keep them away! So is pineapple juice, lady’s deodorant, and licorice! Give me a break. The number one search result for rat repellent right now is a bag of corn cob chips and other essential oils, including eucalyptus, grapefruit, sage, and lavender! A bag of potpourri essentially! AARRRGGHHH!!!
This pulsing red light indicates that either the chamber has been tripped or there is a dead rodent.  98% of the time, a dead rodent is inside.  Simply pick up the entire unit and dispose of the rodent in a trash container or plastic bag and reset the trap.  The dead rodent does not have to be seen or touched.
Here is what happens – a small 1/4″ inch rubber ring is attached inside of the Nooski and stretched to size of a quarter.  When the rat sticks its head inside the trap opening, it trips a lever that releases the rubber ring.  The rubber ring is released around the throat of the rat instantly suffocating it.
One of the main features that customers appreciate about the Rat Zapper is that you don’t have to handle the pest to dispose of it. Who wants to be nose to nose with a dead rat? All you need to do is simply release the creature into the trash, and you never have to make contact with it. Forget the old glue boards that leave live rodents stuck in your space. The old snap traps also don’t work as well as they should. The Rat Zapper will shine a bright red light to let you know that a rodent has entered the chamber. You simply dispose of the vermin and reset the unit for the next one that passes through.
OK, I live in southern Italy, a tiny part of paradise on earth. I am in the middle of ten million Olive trees, quiet, no pollution, no noise apart from the noisy birds, owls and Bats at night as well as the squeaking of noisy MICE. I was humanely catching up to five every night and rehoming them a safe distance away, UNTIL, (drum roll) I discovered these sonic noise mice scarers, since the FIRST night that I installed them, I have not seen a single little micey, NOT ONE and even the so called deaf mosquitoes and other flying nuisances, so YES these little devices do work and work really well.
These little rodents need nothing more than a quarter inch opening (absolutely anywhere) to gain access to a building or home. On top of that, these little creatures can live inside walls. They may use the interior of your home as a base of operations for midnight raids into your kitchen, bedroom, or pantry.
