The Ultimate Ultrasonic Protection from Rodents

PestChaser® technology uses high frequency ultrasound that only rodents can hear to effectively and humanely repel them without the use of poisons or chemicals. Three speakers gives PestChaser® Ultra the most power of all the ultrasonic rodent repellent devices Victor® offers, providing powerful rodent protection for the largest of rooms. The jackhammer-like sound is released at over 80 oscillations per second at varying volumes and frequencies, so that rodents will not get accustomed to it and humans and non-rodent pets cannot hear it.

See a Reduction in Rodent Activity in 6-10 Days

Most PestChaser® users experience a reduction in rodent activity in as little as 6 to 10 days. Simply use one Ultra PestChaser® per large-size room or warehouse space, as directed. PestChaser® is for indoor-use only, and if you have rodent pets such as hamsters, rabbits or guinea pigs, you should move them to another room away from the ultrasonic repelling device.

Arrived timely and looks fine. By Tom

As I have several mouse preventative efforts underway at the same time to keep them out of the car's wiring, and I have no more issues as far as I know, I guess it works. I wish there was a way to know it is working.

I’m wondering if this was worthwhile purchase. By Kricket5

I’m not too sure if they are helping as we have caught a couple mice since having them. I saw one mouse ran right past it the other day, didn’t seem to affect it at all. I’m wondering if this was worthwhile purchase.

Response From Havahart®
Lauren : Consumer Relations Representative

Thank you for taking the time to share this experience. When used continuously, a reduction in rodent activity should be seen within 6-10 days. It is important to keep in mind that the ultrasonic frequency cannot penetrate through solid objects such as walls or furniture and should be placed in an unobstructed area.

We would like to learn more about what is occurring so we may offer assistance. Please feel free to contact us at 1-855-5-VICTOR (1-855-584-2867) with any questions.

Ultrasonic Miracle for older Condo By L M

I didn't know this type of product existed. I was a newer resident to an older building with neighbors on both sides--3-tier apt. 1300 square place. , I became increasingly alert that the apartment needed attention re: spiders, silverfish and etc. but, no mice, rats or snakes-issues. Thus, while putting active attention to other facets (electr., plumb, floor etc), I put attention to pest control, too. Three recommended local pest technicians who came over and serviced the place were a waste of money ($85 each time). No improvement and also I didn't like their attitudes or the fact that each time I saw no improvement within days or weeks. I went to Lowe's and a very informative older associate gave me volumes of exceptional info. Thus, in not wanting chemicals and in not wanting deceased results --I went with a common Victor pest ultrasonic. Immediately I saw a little bit of improvement. Thus, I decided to 3x the strength, so I never would have to worry again and also be totally preventative. I bought an ultra ultrasonic for the garage, one for the living room dining room, one for the bedroom and one for the kitchen. I made sure to plug them in where furniture would not be causing any barrier. I have been in outright heaven.

Ultrasonic Miracle for older Condo By L M

I moved into an older condo, 1200 sq ft. (privately owned). On one side/common wall are longtime, rental tenants and on other side/common wall/private owner. Property is older 1991 construction-3 floors. I saw, nor heard any mice or rats. But, I also did not want to! But, the spiders, pincherbugs, silverfish etc--loved the place and told all their friends, too. This specific unit was a second home to previous resident, so it needed my active attention and problem-solving in the facet of "pests." Calling the pest control people once a month--was getting me nowhere--even though they have a good local reputation....and charging me $85 each time. The technician would leave and even a week later--I would see no improvement. I was also vehement that I needed to stop using those extremely toxic chemical sprays one gets at Home Depot, etc. I also was priority focused it needed to be solved prior to spring and my first spring season. The Lady at Lowes suggested I try one of these units. I did so--and within hours noticed maximum --total--miracle improvement in the bedroom. Thus, I went on website and ordered several. As I ordered my focus was get at least double strength or double potency--of whatever is recommended, to really see if can provide any type of improvement. I got one of these units for the kitchen, one for the garage, one for the Liv/Dining room, one for the bedroom and two smaller ones for each of the bathrooms. I have not seen one anything of any bug, spider or anything of anything of anything---since! I could not be happier! I was unwilling to pay $85 a month and see zero improvement. Unwilling to keep spraying toxic sprays and only making immediate improvement in the immediate situation. Unwilling to be seeing or cleaning deceased "whatever type of pest." I have no idea what percentage of overboard I went with my purchase-- in re: sq.footage, etc. But, I solved the problem I was reasonably priority concerned about and have done so in a permanent way. I also told a few of my neighbors "so they could spread the word". I am 55+ person..

Doesn’t work. Get glue traps. By Mike

Purchased a 3 pack and these don’t work. Put all 3 in our camper for the winter. I clearly see mice running right by it on a camera I have setup in the camper. Found one dead in a glue trap about a foot away from the unit. Very disappointed.

Response From Havahart®
Lauren : Consumer Relations Representative

Hello Mike,

Thank you for taking the time to share this valuable feedback. When using these repellents, a reduction in rodent activity should be seen within 6-10 days. Please keep in mind that ultrasound does not travel through walls or furniture, so it’s important to clear all surrounding objects obstructing the PestChaser®.

We apologize that the units did not work as expected. Please feel free to contact us at 1-855-5-VICTOR (1-855-584-2867) for additional assistance.

Q.Does it have an effect on squirrels as well?

This product is not designed to deter squirrels. It is recommended for mice and rats only.

Q.Can the ultrasound unit be used with an extention cord? I have rodents in my actic and do not have an outlet in the actic.

Yes, this product may be plugged into an extension cord.

Q.I have a variety of pets, including birds. Will this annoy or harm them in any way?

This product can be used around birds as the frequency is well above their range of hearing. It is not recommended for use around rodent pets.
