I purchased one, a week ago, to control fleas and bugs. Also, we have some spiders. The fleas activity was reduced. I don’t want to say that it stopped totally yet. My arms are getting a chance to heal now from the bites I get when sleeping. I believe the product works. I have not seen a single spider around. It’s important to get rid of clutter around the house because ‘things’ will absorb the sound. It may depend on what product brand you purchase. I purchased the “Transonic Pro Electronic Pest Repeller”. I got mine from Gardenfun.com but you might find them somewhere else also. Give it a week or two to see results. My husband agreed about the change in our home.
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.
My Response: Yes, it’s more common for rats to enter a house during cooler winter weather. To answer your questions, no, there is definitely no repellent that will keep them away. But to your other question, how to find their entry points, that’s the vital thing. It basically just takes a very detailed inspection of the home, including every part of the roof, all the vents, the plumbing, etc. Once the entry areas are sealed shut, the rat problem goes away forever. A repellent, even if one did work, would only be a band-aid.

Really try to hit those “high traffic” spots close to where the mice are living with the majority of your traps.  You can also set a few along their pathways to and from their nesting zone.  This is almost always going to be along counter tops, baseboards, and in cupboards.
For those looking to quickly get rid of mice, try out Victor® Fast-Kill® rodent bait stations that come pre-filled with a single-feed mouse poison made from bakery-grade ingredients. To use, just place the disposable bait station near signs of rodent activity. The mouse simply enters the bait station, nibbles on the rodent poison, and the rest is history. And that’s something to feel great about!
When baiting for rats, the distance between placements should 15 to 30 feet apart depending on the foraging range. Heavy or severe infestations may require closer spacing. The amount of bait per placement should be determined by following the rodenticide label.

It’s another widely used one of the most powerful rat trap which is manufactured by the company Victor. This device produces 8,500 volts of electric shock which is able to kill a rodent in microseconds.
Spread peanut butter over the surface of the can. When a mouse scurries up the ramp to eat, in theory, he will leap to the can for the bait, spin off the wheel and drown. I can’t see why this bucket mouse trap wouldn’t work on mice.
When selecting a type of mouse bait, look for strong smelling food bits that will draw the mouse into your trap. Foods high is fat or protein are good choices.  Mice also have a sweet tooth, so sweet sticky candy or chocolate is a very effective mouse bait.
This is a great trap if you don’t want to deal with a messy situation each time a mouse is caught in your trap. Simply deploy it along a rat path, and once a mouse is glued to the board, pick the board and dispose it.
Once crimped, insert the wire into both holes. You will need to bend the second side of the wire to get it in the hole. Just straighten the wire after it’s through the hole. Center the can over the bucket opening and bend the spare wire on the outside of the bucket around the bucket rim to keep the can centered over the bucket.
Since rats prefer enclosed, safe locations, use Protecta Bait Stations with the T-Rex Snap Traps. These stations will shelter the rat; encouraging it to enter and protect non-targeted animals and children from the harm of the snap trap. The Victor Snap Traps are fine traps, but its height will not fit into bait stations. If this is the case, you can get a cardboard box, cut holes in it and place it over the Victor Snap Trap. This method is not tampered resistant, however.
Also be sure to keep these traps securely out of the reach of children and pets. You may need to disable and remove them during the day if children and pets are in the area. The trap can also be covered with a large box (make sure there’s enough space above the trap to allow it to snap) with holes cut into either end. The holes must be large enough for the rodent to enter freely. The trap needs to be placed far enough into the box so that a curious child’s arm or an inquisitive paw cannot reach the trap.
Rats and mice don’t see well, especially when it’s dark, so they follow baseboards, walls, and other straight lines.  When the glue board is placed along a straight line, the rat will usually run into it.  Sometimes they will jump over it, and if that is the case, then using 2 glue boards end to end is the solution.
I bought one from Groupon, only 15US$ I just try it today, try to get rid of cockroach, 2 inches big one from my kitchen. I wonder, will it drive it out of the kitchen into my living room? By the way, the using the device as a hammer comment was funny.
I cut a gob from the original can (using a heated butter knife) and placed it in a metal coffee can, then gently heated it over a low flame.( I did this in my shop, because you certainly don’t want this stuff on your kitchen stove!) Be very careful to not get it too hot, as it will burn. Next time I will use a makeshift double boiler arrangement and heat it with hot water.

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.

Snap traps should be placed in areas of highest rodent activity. These areas can be determined by inspecting the premises for the highest concentration of rodent signs. Look for fecal pellets, tracks, runways, gnawing damage, grease marks, burrows, urine stains (made visible by a black or ultraviolet flashlight), rodent sounds, and live or dead rodents. High activity areas may include darkened corners, along walls, and behind appliances or other large objects.
Like Mark says above, when it was plugged in, my dog reacted to it immediately. I tested this by plugging and unplugging it, and it was obvious that the sound of the repellent (not audible to us) was bothering him.
It might be best not to completely rely on these devices for pest control. Your best bet is to call your local Orkin Branch Office and have an Orkin Pest Specialist come to your home and provide you with a thorough rodent inspection. Your Orkin Pest Specialist will develop a customized, scientifically proven, treatment protocol that best fits your needs.
