Title: Buy them!
Review: We kill spiders - namely wolf spiders- daily in our house. We treat for them inside and out with sprays and granules, to no avail. About a month ago, a spider the size of a small child burst through my mailslot. After a violent struggle involving scorpion spray, a hammer, and many obscenities, i made it out alive.And then i overnighted these plugs to myself- the only thing i hadnt tried yet.Now, it may have been that my mad spider-killing-ninja skills intimidated all the bugs and they ran in fear, or it may just be that i installed these everywhere, but i have not seen one single bug or spider since that day.No idea where they all went, never saw them fleeing, nor found them on glue traps, or found bodies... they were just gone. Super weird, but i wont complain!!!

Title: Bug and mice repellent
Review: I have used these for several years now and they always worked. However, the past two times I have bought these they did not work not quite sure why, I’m beginning to think that people are buying their new ones putting their old ones back in the package and returning them saying they didn’t like the product and I’m getting them. Very upsetting!!🤬🤬

Title: My ears are sensitive to the high setting
Review: If you have sensitive ears, you might experience some discomfort when using ultrasonic insect repellents like the 4 Pack Ultrasonic Insect Repeller. Although these devices emit high-frequency sounds that are designed to be inaudible to most humans, some individuals with sensitive hearing might still pick up on them or experience discomfort due to the high-pitched nature of the sound waves.Ultrasonic devices target pests like rodents and insects by creating a harsh environment for them, but the effectiveness can vary based on the type of pest and environmental factors such as room size and placement. These devices are generally considered safe for humans and pets, but if you're highly sensitive to noise or certain frequencies, you might feel uneasy using one indoors​.

Title: Flies are down inside
Review: Was looking for something to help with these flies and mosquitos. This works great, flies still come inside but they are trying to get out of they die. Placed one in the garage for spiders and haven't seen spiders, I keep it on silent but sometimes will turn the sound on for a minute.
