The scientific claim about how ultrasonic rat traps work is that they emit a loud sound at frequencies that only rats can hear, which makes them avoid certain areas. These frequencies are undetectable to humans and other animals, which makes these devices a humane and effective way of getting rid of rats. Some claims also point to them being able to function as an insect repellent.
When placed near potential entry points to houses and rodent dens, outdoor traps like snap traps and cage traps can be effective if you want to prevent rats from getting inside your home. Some traps are even designed to catch multiple rodents at once before needing replacement, which can give you plenty of use out of a single trap before you need to replace it.
Despite their claims, ultrasonic rodent traps do not work and should never be considered as a solution for short- or long-term pest control. There are plenty of other alternative ways to keep away rodents like traps. With proper planning and execution, these methods can be effective at keeping rats under control.
Though the video is only a few minutes long, it actually took over 1000hours of filming to get the shots that I used. Sometimes days went bywithout the mouse making an appearance, and it only showed up brieflyevery day. I used my imgcomp programto detect motion and save the appropriate images.My camera set-up didn't record sound. But as a silent film, it wasn'tthat interesting. I searched the Internet for some sound effects to addbut couldn't find what I was looking for. So the sound effects (butnot the music) were all made by me. Most I made with my mouth or byscratching or tapping my fingers on my desk. The squeezing through the holesounds took the longest to figure out, but rubbing my fingers on aballoon made a very satisfying "squeezing through" sound effect. Oncethe mouse made it through a hole, I wanted a popping sound like a champagnebottle, but less sharp. Slamming my palm against the opening of a smallglass jar made just the right sound.With so many clips, and all the sounds to add, it took several daysof editing to put this together.But every time I watched some of the clips, I couldn't stop laughing.So I'm hoping this video will have a similar effect on viewers andthat the extra effort becomes justified. My previous mouse experimentshave been very popular, and so far, YouTube has notdemonetizedthem even though they tend to crack down on stuff that anyone mightfind remotely offensive.
Mouse update: Two days later, the shrew managed to squeeze itself through thesmallest hole!
