Trapping a mouse can be a trial-and-error process. But you can take some shortcuts with Victor’s list of best mouse trap baits. As a starter, researchers and trapping experts alike recommend peanut butter bait for several reasons:
You just have to place bait inside the trap, and the rat will come and try to eat it, and it will get caught inside it. It completely escapes proof. Once a rat gets caught, it can’t come out without your permission.
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.
I’m not aware or rats covering their holes. They may push debris back behind them as the gnaw their way through your home. To answer your question about the best bait, are we dealing with a black rat or a brown rat? Depending on the time of the year, you might want to use nest building material as bait.
Experts will tell you that even if you skip the bait but place the rat trap in the right location, you will have success. On the other hand, the best bait and a poorly placed trap are unlikely to lead to results. This involves inspecting the attic and looking for the rat paths. These rodents go over the same paths repeatedly and you can typically recognize them by their grease and droppings. Place the traps along these paths and you don’t really need to use bait. If it makes you feel better, put some peanut butter or dried fruit on the traps and wait for it to work.

I got what I think was just one mouse in the house. And I actually was greatly relieved when I caught it. I bought the Tomcat attractant gel, and plopped a few of these little suckers around. Within an hour of bedtime, I heard a bunch of ruckus in my bathroom. My two cats (those lazy jerks), were fighting over the mouse that was stuck in the trap! ONE HOUR. I felt slightly squeamish, but I felt it was my duty to see what the damage was. I’m a compassionate individual, and I didn’t want to continue using a device that was inhumane.
Rats instinctively use walls and fences as guides. Therefore, they are unlikely to roam into the center of a room or yard. As such, traps are usually most effective when placed along a wall and in a low-light setting. Traps are most effective when hidden along paths where rats are most likely to travel.
Electronic Rat Traps: Bless the people who’ve invented such units! No blood. No squeaking. No mess! High voltage shock kills rats in seconds. The rat gets inside, completing the electric circuit with its body. There is no chance to escape. The electricity is running through its body for at least two minutes. There is no “resurrection” after impact. Easy to empty and clean. You haven’t to touch the corpses, just throw them into a trash can and clean up the tray using vinegar or dish detergent if it’s needed. Remember, rats don’t like the dead rat smell.
I get so many requests for rat control in mountain benches.  Over and over again, I have seen literal mazes of little trails worn away in the grass where rats have scurried back and forth to cat food, birdfeeders, garages, cellar doors, fruit trees, garbage cans, on and on.  It’s like the rats build up their own little metropolitan area with a highway system and everything.  And if they’re in your yard, guess who is running the 24-hour diner. 
Eliminator Robust can be powered by either 4 D batteries or via a Plug-in power adapter. Besides rats and mice, this portable equipment (1.9 pounds0 also works on chipmunks, squirrels and other rodents.

Once you know your rat, whether you are trapping a brown rat (Norway rat) or a black rat, then you can choose the right bait. Black rats are vegetarians. Brown rats eat both plant foods and meat. If you have more than one kind of rat to catch, it is best to use a plant food such as peanut butter as bait.
This handy contraception is black in color and measures 11 x 4.5 x 5 inches. It is powered by 4 D batteries that operate the sensors that activate the 7000V shock. It is energy efficient and will kill as many as 30 rats before the alkaline batteries need to be replaced. Unlike other traps that leave a bloody mess or odor, this one makes clean and mess-free kills.
__The ‘Professional’ style trap rarely works. I have watched rodents OH-SO cautiously not touch the yellow pad and ever so lightly nibble on the bait. Only once did it work. Two mouses/meeses were at the trap and were wrestling for the food where the trigger was accidentally sprung. But, it caught 2 mouse’s in my house’s.
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?
The Rat Snap Trap has a removable cup so baiting can also be done prior to setting the trap. After baiting, open the trap by pinching, like opening a clothespin, until you hear a click to indicate it has locked into place.
The Victor Electronic Rat Trap is the ultimate in rodent control. It works by delivering a humane, high-voltage shock to effectively kill the invading rat. This powerful device is capable of killing up to 50 rats per set of fully charged batteries (4 C), making it a great value when you’re dealing with a sizable infestation. It’s also easy to use. Get started by simply applying a high protein bait in the provided bait cup, place the trap in a location with high rodent activity and turn it on. The trap is equipped with advanced smart circuit technology, which senses when a rat enters the tunnel, triggering the system to deliver a humane, high-voltage shock once the rat steps on the electrified plate. Since rats have the ability to restart their hearts after an electrical shock, this trap applies shock for 2 minutes to ensure higher kill rates. After making a catch, a green LED light blinks to indicate a kill. For your convenience, the trap’s design allows you to easily dispose of the dead rodent without having to see or touch it. The new and improved design of the electronic trap has a removable kill chamber, which provides better plate access so you can easily clean and bait it in between uses. These traps require no poison or chemicals and can be used anywhere inside your home or business to ensure years of effective rat control.
Dealing with large rodent is no easy task. They are very destructive and can cost thousands of dollars of damage to your home. Sometimes, they nest in the walls and then cut holes in the walls to make easy access points. They can make a mess in cabinets, pantries and even climb into bed with you. If you have children or pets in the home; the problems can be even more extreme. When you have an atypical problem, just any old trap won’t do. The products here have all been tested and found to be perfect for the home or office needs. They are so powerful they can work on a farm or in the middle of the city. Rats these days the pests are very savvy and it takes a product that is one step ahead to catch them.
Black rats, which scale trees and enter homes through coin-sized holes in attics, find peanut butter irresistible. Brown rats, which typically rummage through garbage and snake their way inside homes via tiny cracks, can be tempted with a smelly cheese.
We had rats and mice pretty bad our house smelled like a rat cage. I cleaned my house spotless could not get rid of them they would not go after poison or traps they stayed clear of them. I am pregnant and was getting to sick from being home. After being gone at my moms for two weeks because I couldn’t deal with the smell and the rats my husband wanted me home so he got 5 of the small rodent electronic plug ins for our room and bathroom and one big one for our living room and kitchen. I have two dogs haven’t affected them at all. But after my husband plugged all of these in he called me and said he got them. Not even 24 hrs later i came home. my house didn’t smell nearly as bad and haven’t seen any since except for one. cleaned my house again and haven’t seen any droppings or pee stains anywhere. The one I saw I’m pretty sure ran out. My house is spotless and smells amazing and it’s been 2 weeks so I’m pretty sure these work. We have had a rat problem for almost 6 months and now they’re gone.
