Ultrasonic Rodent Repellents

Ultrasonic rodent repellents claim to use "ultrasonic sound waves attack the auditory and nervous systems of most common pests causing them pain and discomfort." According to Louisiana State University, the frequency hearing ranges of various animals are (in Hertz):


Rats: 200-76,000 Mice: 1,000-91,000	Humans: 64-23,000 Dogs: 67-45,000 Cats: 45-64,000	Gerbils: 100-60,000 Chinchillas: 90-22,800 Guinea pigs: 54-50,000Louisiana State University: Frequency Hearing Ranges in Dogs and Other Species

If you review some of the claims the devices make:
1. One device stated that the range of sound waves emitted from its device was between "approximately 30,000 to 65,000Hz."Health Safety Pro: Electronic Pest Repeller - 5000 Sq Ft Coverage: Health Safety Pro Since cats can hearing ranges up to 64,000Hz, they would most likely be able to hear it.
2. Another device claims that it uses "patented Digital Pulse Technology" that is safe for pets except "hamster, gerbil, mink, chinchilla, guinea pig or similar pet."Official Home Page: Riddex Plus Digital Pest Repeller - Electronic Pest Control - Tv Website Notice that cats hear better than gerbils and guinea pigs. Cats, dogs and people hear better than chinchillas. Therefore, if it is capable of bothering them, it should be bothering the rest of us.

Ultrasonic devices have been tested both in laboratories and in the field and most of the results showed that these devices are not effective.University of Tennessee: Managing Pests Around the Home The same goes for electronic, magnetic and vibration devices.UCIPM Online: House Mouse Management Guidelines
1. In the 1980s, the Federal Trade Commission forced several companies to give refunds after charging them with false advertising.University of Nebraska - Lincoln: Ultrasonic Pest Control? Save Your Money
2. Furthermore, ultrasonic devices do not penetrate behind objects and mice quickly become accustomed to regular repeating sounds.UCIPM Online: House Mouse Management Guidelines

Glue Traps or Glue Boards
- Glue traps, or glue boards, are essentially a tray of very sticky glue. The mouse is then caught when it steps in the glue. Unfortunately, this does not always happen. Here is why you should avoid using glue traps:
1. Although glue traps are designed to suffocate mice (which can take hours), they often die instead from starvation or dehydration (which takes several days).Helping Animals: Glue Traps During this time, mice have been known to try to free themselves by tearing their skin off and/or gnawing their legs off.About.com: Using Mouse Glue Traps to Get Rid of Mice
2. The Center for Disease Control (CDC) does not recommend glue traps because they can increase your risk of being exposed to hantavirus.Center for Disease Control: Trap Up!
3. Glue traps often trap and kill birds, squirrels, snakes and even kittens.Helping Animals: Glue Traps
4. Children and pets can get caught in the glue, which can be very difficult to remove. (Use vegetable oil.)About.com: Using Mouse Glue Traps to Get Rid of Mice
Poisons (Rodenticides)
- There are three types of rodenticides on the market today: acute toxins, calcium releasers and anticoagulants. Most sold today are anticoagulants (or blood thinners) that cause mice to bleed to death internally.The New York Times: Mice News They can take a long time to kill. Some of them require rats and mice to eat them each day for a week before they die.The University of Georgia College of Agricultural and Environmental Sciences: Rats and Mice: Keep Them Out of Your House and Yard Here are some reasons why you don't want to use rodenticides in your home:
1. Mice that feed on the poisons will die where they live.Utah State University Extension: How Do I Keep Mice Out of My House? In other words, in the walls of your home. This can cause a terrible odor as the mice slowly decay.Georgia Faces: Menacing Mice Move Indoors (December 20, 2007)
2. To kill all the mice in your home, it can take up to three weeks before they are effective.Illinois Department of Public Health: House Mouse Prevention and Control

4. Pets and wildlife are also in danger should they eat mice that have been poisoned.University of Nebraska - Lincoln: Controlling House Mice
Cats
- We grew up seeing cats chasing mice on cartoons such as Tom and Jerry, Pixie and Dixie and Mr. Jinks, or The Simpsons's Itchy & Scratchy. It makes sense that cats would be great at getting rid of mice. This is not true.
1. While it is true that mice are instinctively afraid of cats and that the initial odor of cats will scare mice away, the smell of cats can also acts as aphrodisiac for mice.Discovery News: Fearless Mice Cuddle Up to Cats (December 13, 2007) MSNBC: Cats Can Help Male Mice Get Ladies (May 9, 2008) Scientists exposed mice to the smell of cat urine for several weeks. After two months, instead of being afraid, male mice became more aggressive and more attractive to female mice in heat (which means more little mice).MSNBC: Cats Can Help Male Mice Get Ladies (May 9, 2008)
2. Furthermore, mice have gotten used to living with pets and often obtain food from the pet's dish or from what pets spill.Illinois Department of Public Health: House Mouse Prevention and Control
3. Mice are capable of finding places to live and hide that are out of reach from cats.UCIPM Online: House Mouse Management Guidelines
4. It is possible that cats might be able to spread hantavirus if they come in contact with infected mice.About.com: What Else Did my Cat Bring Home?

Step 3: Trapping Mice
- Trapping is the best way to get rid of any mice in your home because they do not rely on hazardous rodenicides and you can safely dispose of any trapped mice.UCIPM Online: House Mouse Management Guidelines There are two types of mice traps available: live traps and snap traps.
Live Traps
- Using a live trap is the most humane method for removing mice from your home. It's even recommended by PETA. Just as the name implies, the traps are designed to capture mice alive. You can also make your own.Helping Animals: Living in Harmony With House Mice
1. Set traps against the wall in areas where you have seen signs of mice.
2. Check traps at least three times a day.Helping Animals: Living in Harmony With House Mice
3. Place a towel over the trap to keep the animal calm.
4. Transport captured mice to a designated release site or a wooded area at least one mile from your home.
5. If you live in an urban area, take mice to a veterinarian or an animal shelter to be euthanized.Helping Animals: Living in Harmony With House Mice
6. Live traps are sold at hardware stores, humane societies and online:
  1. PETA Catalog: Humane 'Smart' Mousetrap
  2. Google Product Search: "Live Mouse Trap"
  3. Amazon.com Product Search: "Live Mouse Trap"
Snap Traps
- There's an old saying about snap traps, "The early bird gets the worm, but the second mouse gets the cheese".Quote Garden: Humorous Quotations While snap traps are less humane than live traps, they are more humane than poisons and glue traps. They are also recommended by the CDC.Center for Disease Control: Trap Up! They are also inexpensive and effective when used correctly.Illinois Department of Public Health: House Mouse Prevention and Control
1. Set traps so that the trigger is sensitive and will spring easily.Illinois Department of Public Health: House Mouse Prevention and Control

3. You can purchase snap traps that are covered and easy to set.
4. Dispose of mice quickly by placing them (bagged) in an outside garbage container or by burying them.Utah State University Extension: How Do I Keep Mice Out of My House?
How to Set and Bait a Trap
- No matter what type of trap you purchase, it is important that you set, place and bait them correctly. If you don't, you'll be unsuccessful.
1. Set traps close to walls, behind objects and in dark corners where you know mice have been active.Illinois Department of Public Health: House Mouse Prevention and Control
2. Make sure you have enough traps. Using too few traps is a common error people make.Illinois Department of Public Health: House Mouse Prevention and Control

- Once traps have been set for two weeks without catching a mouse, and all other signs are absent, you can be sure that the mice are gone from you home.
Conclusion
- Getting rid of mice does not have to be a nightmare once you know how. Best of all, while it may take more work in the beginning, many of the preventative methods will last for a long time.
