Bell+Howell Ultrasonic Pest Repeller Plug in Device Assorted 8 Pack, Effectively Aids to Repel mice, Bugs, Rats, Rodents, Mosquitos, roaches, Spiders and Ants Chemical, Odor and Sound Free

I bought this set at the beginning of September 2024 and did not believe it was working. I am so glad I didn’t write this review that second week!Last winter we had heavy snow and a bad ice storm. A massive limb fell in the back yard and narrowly missed the house, however; it gouged a hole in the exterior the size of a half dollar. And every mouse in town got the notification!I immediately jumped into action with all the wrong tools and devices: glue traps, regular wood traps with over-ripe bananas (mice love over ripe bananas-they ate the end off one on my counter!) the clue box AND the electric box… not a single mouse got near the electric chair; the roller bar over the bucket (the clawing of a drowning mouse is not soon forgotten); the maze with the green chunk of poison (disgusting to find one floating in Dupree’s doggy water bowl) and in his defense— Shih Tsu’s are not mousers (fyi-he’s not great at math either except he’s has mastered the art of a high 5) but back to my serious Rodent Occupied.I spent months trying product after product and I was quickly getting overrun. But when they gnawed through and feasted on my new loaf of Dave’s Killer Bread they crossed a line. I told a friend from grammar school and she recommended this product: after a gulf coast hurricane she had mice and rats in her garage.For 40 bucks, it was the last stop on the road to hiring an expensive exterminator. And Dupree was a hard no on agent-oranging the place with chemicals and he put a paw down on buying more inhumane contraptions and torture devices.When they arrived I strategically placed them in each room, following the instructions closely: there are 3 sizes included, the large ones for your biggest rooms, have a side plug so you don’t lose access to the outlet. The medium ones for smaller rooms and the smalls for bathroom and countertop. Also position them so nothing is blocking them— be sure they aren’t covered by furniture or or drapes etc. Then I kicked back and waited for my miraculous, humane mouse rouster to commence with the evictions.By day 7? I was asking for exterminator referrals. I was still cleaning my countertops and EVERY morning. So frustrating because I was also deep cleaning every room, drawer and closet and putting every morsel of food into lockdown… and I was still set traps (the best ones are white plastic from Tomcat with attractant gel) and performing trash bag burials.By day twelve? I was ready to yank them out and return them— instead I ordered the Tomcat set with 2 more traps, attractant and the threshold spray. But I was noticing less activity and doing less bleaching of the countertops and appliances.By the time the Tomcat set arrived, I didn’t have time to use it. Dupree and I had a 4-day girl trip with my college sorority sisters… 40 years! But I knew I would have to shell out hundreds and hire an extermination team when I got home.Day 24— Home at last and in a little bit of shock. All my traps were still set… and in the entire house (1500 sf) I only found a couple of droppings. The siege was over.Today is day 60 and still no sign of intruders or repeat offenders. Not a single trap’s sprung…But winter is coming…Tomorrow, Darrell From The Block Handyman Services is coming to change my furnace filter, clean the gutters, check loose ductwork in my crawls space and… spray that Tomcat Thershold Rodent repellent on every possible point.Others have complained about the night light and the red pinpoint light that emits the ultrasonics that ensure continued eviction. I don’t notice any of that…a fair trade off for a system that actually works.START with this product. I wish I had. I would be a couple hundred bucks richer. Order it today with the Tomcat repellent bundle: threshold spray, 2 white traps and attractant gel. Use the Tomcat to eliminate as many as possible. Then while it gets to work— do the same. Eliminate spaces and materials for them to nest.I hope this is helpful for you. Dupree is going to edit and post.

I got these and one doesn't work haven't heard back from the companySo far I think they're working.. we have a lot of crickets and I haven't seen any since using these .

I had a serious infestation of ghost ants, so I decided to try the Bell & Howell Ultrasonic Insect Repeller. It worked like a charm! Within a few days of plugging them in, the ants vanished from my house. Now, nearly a year later, I haven't seen a single one since. You won't regret investing in this product.

It take time about 4 months to see differences it works. You must also make sure your house smell good and lived

So far so good.

Because the light is flashing I’m not sure if it really working. I didn’t have roaches but lately I been seeing a few even after the plug has been in for 5 days.

It started working right away! I would recommend this to anyone thinking of calling a monthly exterminator! Try this first 🥇!

I put several in a small barn. They don’t seem to work at all. The mice run around in close proximity to the unit going about their business as usual. The mice are not leaving.
