Rat killer (high voltage shock)

With these five simple steps, you can trap a mouse or rat on your first night and get rid of mice/rat/mouse for good.

Holes the size of quarters are large enough for mice to pass through
1 Find Their Patterns
Mice are active mostly between dusk and dawn, but you can spot evidence of their activity anytime. That lovely sight of mouse poop is often your first sign—each mouse drops up to 75 of the little black pellets a day!

They move along walls and avoid open spaces, so follow where you see the mice droppings in both directions and you'll know where they've been traveling. Mice gnaw at drywall and similar materials, creating clean-cut holes up to 1 1/2 inches in diameter, but they can fit through any dime-size opening they find. Look for the holes and debris in the dark corners of your kitchen and laundry room.

Check for caches of pet food and birdseed in unexpected places—behind appliances and furniture, and near other undisturbed spots in your house. Mice build nests of paper and other fibrous material in sheltered spots near constant heat, such as refrigerators, ovens, and water heaters.

2 Choose the Best Mouse Traps
The classic snap traps and modern electronic traps capture mice and make sure they're gone for good. Snap traps are the least expensive, and they're reusable or disposable, your choice. With an electronic mouse trap, you don't have to see any mice or continuously check traps—an indicator light lets you know when one has been caught. If you'd prefer to get them out of your house unharmed, you can use live mouse traps that let you release them far from your home. After the pests are gone, set up Aosion mouse trap rodent repellers that emit ultrasound waves you and your non-rodent pets can't hear, but that drive mice away. If you are having trouble deciding what trap would work best for you, check out our trap guide for more information.

3 Pick Bait Wisely
Mice are strongly attracted to high-calorie foods, such as peanut butter, hazelnut spread, and chocolate. In winter, mice build nests with materials like cotton balls, dental floss, yarn, and twine, so they work as bait too. The food that mice have been feeding on in your house, whether that's pet kibble, birdseed, or candy, may be the best mouse trap bait. For more information on baiting, check out our mouse baiting guide.

4 Place Traps in the Best Places
As the rodents primarily travel along walls, you want to set your mouse traps at right angles to walls, with the bait and trigger side closest to the wall. Set a trap every 2 to 3 feet along the walls where you've noticed evidence of mice activity. Wear protective gloves when handling mouse traps and bait to keep mice off your scent. (If they sniff out your presence, they may avoid the trap.)

The very best spots for mouse traps are in enclosed spaces, inside cabinets and closets, and beneath or behind furniture and appliances. Around your range or oven is a favorite haunt for mice, because there's a steady supply of warmth and tiny bits of food. If there's a drawer for storing pans beneath your oven, set a mouse trap inside it.

5 Check and Reset
Look in on your mouse traps the first morning after you set them, and every morning after. Studies show you are likely to catch more mice on the first night you set out traps than on any subsequent night. Be sure to set a lot of mouse traps from the start, so you can capture as many as possible quickly.

Mice reproduce so fast and abundantly, you are certain to have more than one in your home at a time. So don't quit after you've caught one. Keep setting and checking mouse traps until you haven't caught a mouse for a week.
