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.

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.

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.

Failure By Ted

Doing very well for 3 weeks until evidence of a mouse in a kitchen drawer yesterday. Caught it today on glue paper. The drawer is 12 feet from the unit.

Response From Havahart®
Susan : Consumer Relations Representative

Hello Ted,

Thank you for taking the time to share your feedback!

While they will protect the room as a whole, the ultrasonic sound waves produced by this product are not able to go through objects such as walls or cabinets. For that type of area, we recommend a different type of repellant such as our Victor® Scent-Away™ Natural Rodent Repeller Packs™.

We hope this information is helpful! Please feel free to contact our Consumer Relations Team at 1-855-5-VICTOR (1-855-584-2867) with any questions.

good in a confined space By Ralph

These do work in a confined space if you can get them blasting before the rats settle down. In my experience, if the rats are already used to a place, it is more difficult. It is September in Northern California, and we have rats in a grape arbor in the yard. I hear them at night, eating grapes. I do not want to put out poison or traps because of pets and native wildlife. So I tried putting an Ultra PestChaser in a wooden box and put it right up close to the grape arbor. I think they are still there, but the ultra sound seems to make them quieter at night.

Call pest company By Varmentpuntang

Waste of MONEY, Just like all the pest companies told me that after awhile the rats will come back as they realize no harm comes to them other than noise, still have rats and they just run right pass this like it's not even there.

Response From Havahart®
Lauren : Consumer Relations Representative

Thank you for taking the time to share this experience. These repellents output continuously which causes discomfort and creates an unwelcome environment for the rodents. After repeated exposure to the product, the mice and rats will be driven away.

For best results, place the units so that they are not obstructed by furniture as the frequency does not go through solid objects such as walls or cabinets. For heavy infestations, we recommend the use of traps in conjunction with the repellent.

We hope this information is of help. Please feel free to contact our Consumer Relations Team at 1-855-5-VICTOR (1-855-584-2867) with any additional questions.

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.

This product is designed for indoor use only. We do not recommend using it in a crawl space.
