Learn How To Catch A Rat

What is the best bait for a rat trap?

For rat traps, use peanut butter, bacon, fruits, vegetables, cereals or meats as a bait.

Mouse Traps

How to catch a mouse

Electronic mouse traps are the quickest and easiest way to catch mice. They are easy to use, with no setting or glue required. Their no-touch technology, plus 100% kill rate makes them an ideal way to control your mouse problem. If you would like more information on how to catch a mouse, view our complete guide below.

What baits should I use in my mouse trap?

For trapping mice, use peanut butter, chocolate, oats or nesting materials such as cotton or string as a bait.

Where should I place my mouse trap?

Place traps perpendicular to the wall near signs of rodent activity (to find out where your area of high activity is please see Diagnose Your Home). For Rats, place traps out unset for a few days so they can become familiar with it.

I caught a mouse! What now?

Be sure to check traps daily and replace as needed. Wear gloves when disposing of rodents. You can also disinfect the area with a household cleaner if you are concerned that there is a possible threat to your health.

How many of mice are born at once? How do I know that I've trapped them all?

It's practically impossible to tell when you've trapped them all. You should continue to trap as long as you see mice or notice signs of activity.

The most apparent sign of an infestation is fresh droppings.

General Trapping FAQs

What is the most common mistake in trapping?

The true number of rodents present is underestimated. As a result, not enough traps are used. Although you have killed a few rodents, the remainder of the population continues to multiply.

Where should I place my trap?

Snap traps should be placed perpendicular to the wall near signs of rodent activity (to find out where your area of high activity is please see Diagnose Your Home. By placing the snap trap perpendicular, you ensure the rodents interact with the trip pedal as they travel along the wall, no matter which direction they come from. For Rats, place traps out unset for a few days so they can become familiar with it.

Electronic traps, live tunnel traps, and tented glue traps should be placed parallel to the wall so rodents are able to walk directly into the tunnel entrance as they travel along the wall.

General Trapping FAQ

Are expanded trigger snap traps superior to regular traps?

Yes.

I'm having trouble trapping rodents. What can I do?

Rodents will travel the same pathways over and over. Those pathways are always along the base of a wall or similar vertical structure. Traps should always be placed in the pathways. Pairs of traps can be employed since mice will often jump over obstructions in their normal path.

Use two traps in the position mentioned above or place them length-wise, end-to-end (red "V's" on traps pointing towards each other) so that the bait pedal end will be encountered first as mice approach from either direction. For trickier spots like walls, air ducts, and crawl spaces, check out our article, How to Get Rid of Mice in Your Walls.

Snap Traps

How do I set a snap trap?

Remove the small staple holding the locking bar to the wood base. Place bait inside curl found at the end of the bait pedal. Pull back bow and hold down with thumb. With other hand, engage the curved portion locking bar under the small, V-shaped lip on the bait pedal.

Watch How to Set a Mouse Trap:

 

The snap trap's bait was eaten but no rodent was caught.

Try to use the least amount of bait possible in any style mouse trap used. The more bait you use, the easier it is for rodents to remove it without disturbing the traps. The goal is to have them apply extra force to the trigger pedal with their nose/tongue to remove the bait. To do this press a small amount of bait into the bait pedal.

Additionally, by using nesting materials like a string, mice will need to tug on the material to free it from the trap.

Be sure to position the snap trap so that the baited end of each trap is placed perpendicular to the wall. Rodents generally travel with their bodies against a wall for protection. It may be necessary to bait a rat trap without setting the trap and allow the bait to be eaten a couple of times. Then set the trap with more bait. Rats tend to shy away from new objects so this method gets them accustomed to the trap. Mice are more inquisitive than rats, so pre-baiting is less likely to be needed.

Glue Traps

Does a glue trap need to be baited?

No. Mousetraps of any kind simply need to be placed in known mice pathways. The mice will then encounter and rapidly explore the traps.

Are glue traps efficacy affected by temperature?

Yes. If it is too warm, the glue will be too liquid and may begin to run. If it is too cold, the trap becomes less sticky.

My glue board is covered in debris - what happened?

Some adult mice have been known to cover traps with debris that will render them ineffective. Typically, they will do this if the trap is in their familiar runway.

Why did I find several young mice on 1 glue trap in 1 night?

Young mice from the same litter tend to run around together.

As a result, they will all rush onto the same glue trap.

Voles

Will your live catch mouse traps work for voles also?

Unfortunately, no. Typically voles will not enter this type of live catch trap. A better alternative is the Havahart Cage Trap. It's a cage-type trap designed for small rodents.

Pets & Traps

How do I free a mouse or pet's paw from a glue trap?

The glue from all our traps can be removed easily. Liberally coat the glue on the paw with vegetable oil. The oil will dissolve the glue within a short period of time. The oily residue can then be removed by washing with mild soap and warm water.

How do I keep my pets away from the mouse/rat traps?

Place the trap inside a small cardboard box that has enough height to allow the trap to snap. Cut a 3" x 3 opening on two opposite sides of the box. Place the box with a baited trap in a known rodent path.

Rodent Repellent Questions

How Do They Work

How does Ultrasound work?

Ultrasound is a frequency of sound too high to be heard by humans. Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. The Victor® PestChaser® sweeps a frequency of 32-62 kHz. Rodents find this sound irritating and will avoid it if possible. The non-repetitive frequency levels cause additional discomfort and do not allow the rodent to become habituated to the sound.

For additional effectiveness, the loudest spike in sound replicates the sound of a dominant male rodent. Rodents are very territorial and will constantly fight to establish dominance. The sound of a dominant rodent will discourage others from inhabiting a territory.

It is important to note that ultrasonic frequencies do not travel between walls. So for the most effective rodent control, ultrasonic units need to be placed in multiple rooms.

How does Ultrasound affect rodents?

Ultrasound can repel rodents by subjecting them to intense auditory stress. This method is a classic animal behavior modification technique.

Unlike traps and poisons, ultrasound does not kill rodents. The PestChaser® has the ability to provide long-term reductions in rodent populations by creating a "rodent-unfriendly" environment that discourages rodent infestations.

What are the most common mistakes people make with repellents?

Ultrasound Alone to Control Infestation: The most common repellent mistake is using ultrasound units alone to control an established infestation. Simply plugging in a PestChaser® will not send rodents running for the door and out into cold winter temperatures if there is still sufficient food & shelter in your home or shed. It is important to also incorporate sanitation and exclusion techniques. Additionally, traps and baits should be used in conjunction with Ultrasonic devices.

Not Enough Units are Used: Ultrasound does not travel through walls so it is important to place 1 in each room.

Poor Placement: Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. Placement behind a couch will not allow waves to bounce around freely, causing a hostile sound environment.

What sets the Victor® PestChaser® apart?

The unit constantly pulses, sweeping through a targeted frequency range with multiple spike points numerous times each minute. This highly complex sound pattern is specifically designed to discourage rodents from acclimating to their environment.

Does the Victor® PestChaser® interfere with other equipment?

No, it will not interfere with pacemakers, garage door openers, or any other electronic equipment.

Does ultrasound affect insects?

Some insect species can produce or perceive sound in ultrasonic frequencies and are affected by high-frequency sound. That is not to say that it can effectively repel them or control them.

There has been little true scientific research to determine if ultrasonic sound generators could produce effective insect control results. You may find that some insects seem to respond to ultrasound while others are oblivious to it. The PestChaser® should not be used for insect pest control.

We believe that it is improper for any company to make specific insect claims unless backed by validated scientific studies.

What about "electromagnetic" pest repellers that claim to repel pests behind walls?

These devices claim to somehow alter the electromagnetic output of common house wiring to turn your whole house into a giant pest repeller and drive all species of pests out of the walls of your home.

In fact, there is scant credible scientific research to suggest that electromagnetic fields have any repellent affect on any living creature, much less specific pest species (mice, insects, etc.).

The EPA and U.S. Postal Service took action to remove all "electromagnetic" (not ultrasonic) pest control devices from the market in 1980 when a flood of them entered the market. Additionally, Health Canada has banned the sale of electromagnetic pest repellers in Canada. And finally, there are serious questions as to the advisability of increasing one's exposure to electromagnetic energy.

How To Use

How much area does a unit cover?

The sound generated by each repellent unit can cover an average size room up. While these high frequencies are called sound, ultrasonic waves act more like light than like sound. Imagining the speaker is a floodlight; you can visualize how ultrasound travels. It will radiate outward in a cone shape, throwing "shadows" behind solid objects such as furniture, and casting little "illumination" into other rooms.

Coverage of multiple rooms requires the use of multiple units.

Where should I place the unit?

First, identify a room that has signs of rodent activity. Rodents are nocturnal creatures, which means they rarely surface during the daytime. Look for the signs of an infestation: chewing or gnaw marks, droppings, tracks and nests. Next, plug the unit into an outlet which is open to the rest of the room, not behind furniture where the sound waves may be blocked.

Ultrasound is reflected by hard surfaces and absorbed by soft surfaces. In a room with mostly hard surfaces, like a kitchen, ultrasound will “bounce” around giving more effective coverage.

The ideal placement would be one that allows the sound waves to cross in front of an entrance way.

How do I know the unit is on?

When powered up, a red LED light will be visible indicating that the unit is broadcasting the high frequency ranges needed to repel pests.

NEVER put your ear up to the speaker once it has been plugged in. The powerful sound waves may cause damage to your ear drums.

How long until I see results?

Allow 2 weeks for ultrasonic sound waves to affect pests with an established food source. For established infestations, it is necessary for you to also use baits and traps to reduce the population.

The unit lasts for 3-5 years.

Pets & Other Questions

How much does it cost to operate a PestChaser®?

PestChaser®'s are very economical - it costs less than a penny a day in electricity.

Is Ultrasound safe for pets?

The PestChaser® sweeps a frequency of 32-62 kHz, well above the range of hearing for humans and non-rodent pets like cats, dogs, birds, and fish. If you have rodent pets such as a hamster or guinea pig, move it to a room without a PestChaser® unit.

How Do They Work

How many pellets of the second-generation anticoagulants does it take to kill a rodent?

Usually only a few pellets will kill a mouse. For rats, usually 6-30 pellets are required. Both rats and mice will continue to feed for several days until they succumb to the effects of the poisons.

Will rodents leave the building to die?

Poisoned rodents may die anywhere, including in some very inconvenient areas. There is no evidence the rodents exit buildings "seeking water" and then die outside. Most times, poisoned rodents succumb in their nests.

How long does it take for rodent baits to work?

With Victor® Fast-Kill™ rodent baits, once a rodent has consumed a lethal dose, it will die in 12 hours to 2 days. Additionally, once the rodent consumes a lethal dose they will stop feeding which greatly reducing the risk of secondary poisoning. Victor® Multi-Kill™ baits will kill a rodent in 4 to 5 days.

What does it mean to see droppings the color of the bait?

Colored droppings indicate a rodent has ingested and digested the bait and its active ingredient. It takes several days for most bait to kill a rodent. Mice produce upwards of 50 or more droppings every day, rats 30-40. Thus, some droppings will be passed through the body containing the green, blue, or red dye of the rodent bait.

How To Use

Should I broadcast rodenticide bait pellets?

No, you should not broadcast (spread the loose pellets) the bait. If desired you can tear a corner on the bait pack, otherwise just place the pack in the desired location. Do not scatter the bait.

Baits pellets

How often should the rodent baits be replaced?

Most recommendations suggest changing out rodent bait every 4-6 weeks. Very moldy or decayed baits are unattractive to rodents, and thus may not be any better than no baits at all.

Pets & Rodenticides

Will my pets be harmed if they eat mouse or rat poison?

Rodenticides can be harmful if ingested by domestic pets or non-target wildlife.

To prevent exposure use the following precautions:

  • Store product that is not in use in a location out of reach of pets.
  • Apply bait in locations that are out of reach of pets and other non-target wildlife, or use a bait station for the bait.
  • Collect and dispose of any dead rodents and left over bait right away.

What should I do it my pet eats mouse or rat poison?

Call the poison control number located on the package immediately for more information. This information is required by the Environmental Protection Agency (EPA) to be on all rodent bait packages.

Proper Storage

Is it important for baits to be stored away from chemical odors like Insecticidals, cleaning agents, etc.?

M917

In some cases, it may be crucial. Rats can taste chemicals in their food in parts per billion. In infestations where rodents may have readily available food sources to them, they have the option of rejecting foods that have chemical tastes.
