I kinda had it on loud speaker. It got rid of the fox & wife 😢. Not sure what scared the fox off. Me and the three kids starring at it with binoculars looking for a reaction or the noise. Might have been the nonstop youtube advents
Je suis dehors à l'arriere de ma maison. Elles volent autour de moi, nombreuses. Environ 8, assez près de moi. Je me demande si cela les désoriente et souhaite qu'elles quittent cet endroit ah lala !
This sound works really well; I managed to get a bat out of my apartment. Just be persistent. First, I searched the entire apartment, moving furniture, wardrobes, checking corners, curtains, and every nook and cranny, but I couldn't find it. Then I turned off all the lights, sat in one room, turned on these frequencies on studio monitors, and turned up the volume for a few minutes. After a while, it started going crazy around the apartment, flying everywhere, clearly disturbed by the sound. Eventually, I caught it by cornering it with a shoebox and then took it outside with a cloth. The little creature bared its teeth in "self-defense." Although bats navigate through ultrasound (which humans can't hear, in the range of 15 kHz to 90 kHz), they have very poor vision and rely heavily on their hearing to function. Bats produce sounds like squeaks or chirps. Using "echolocation," they can perceive the echoes of sounds they make to navigate and hunt efficiently. Bats can detect frequencies above 100 kHz, and possibly up to 200 kHz, which is beyond human hearing and studio monitors. Therefore, the combination of frequencies up to 20 kHz on this link worked really well.
Yup works for me. I used it 24 hours ago, there were like 15 20 bats on the tree nearby, my ears had started to hurt because they screamed soo much. If it didn't i wouldn't do this. I feel like an ass but it was me or them. I used it a day ago and they didn't come back to the tree since, they went to another tree nearby and i had to use it again. Only used it for a minute or 2 in total, played the video and pointed the speakers towards them and kept moving the mobile round and round, up down left right and now its gone.
