Bird-X Woodpecker Pro Sonic Repeller Review

I would like to review 'Bird-X Woodpecker Pro Sonic Repeller' after
using about a month.Bird-X makes a lot of kinds of deterrent devices,
such as Sonic Bird Repellent Devices, Ultrasonic Bird Repellent
Devices, Animal Pest Repellent Devices, and Visual Bird Scare Devices.
Among Sonic Bird Repellent Devices, I tried Woodpecker Pro which is
particularly targeting woodpeckers. I was fighting with woodpeckers
for several years. I never had a good luck. After several defeats, I
decided to go for this expensive device (about $250). I thought if it
works it would be worth while to invest that amount. Listening to a
tech support's advice, I purchased a visual deterrent (a prowler owl)
and an external speaker together with the sonic device. I installed
the main system facing south and the external speaker facing
north.North and south sides are long edges of my house. In this way
the sound covers pretty much everywhere of my house. I walked around
house to make sure I could hear the sound loud and clear every corner
and wall of my house. The sound wave has a relatively long wavelength,
so it can bend (diffract) well. Thus, I didn't have a hard time in
hearing the sound. I installed the owl on the most targeted wall by
woodpeckers. The main device has a lots of settings such as interval,
day/night mode, random mode, and 8 choices of different predators
recordings (4 for woodpeckers, and 4 other general predators).For the
recordings, one may turn on and off individually. I turned on all 8
recordings and chose settings day time only, interval 5-10 minute,
random mode. It seemed to work for about a week, but a woodpecker came
and started pecking. The woodpecker didn't seem to be bothered by the
sound at all. It was pecking the wall while the recording was being
played.I called the tech support and asked. They told me not to turn
on all 8 recordings and suggested me to use 2 or 3 settings and to try
to find the recording that works by experimenting. I followed their
advice and turned on 3 recordings only. About 3 days, one attacked my
house again. I changed the setting. And a few days later other
woodpecker was pecking the wall again. And I chose another combination
of the recordings, increased the volume of the sound and chose the
interval more frequently to 1-4 min. After a few days, a woodpecker
was pecking the wall about 3 feet away from the owl. The device simply
did not work for me and my house.It does make a lot of noise. In my
case, my house is located in a rural area. So, the device didn't
bother my neighbors much. In a crowded city, the noise may be problem
even if the device works. Well, wherever you live, if it doesn't work,
there is no reason to keep. Although I used longer than 30 days return
period, they were quite friendly every time I called and were willing
to give me money back.The bottom line is that you really have to try
and experiment to see if it works at your house. In my case, it didn't
work. Now, I have to other alternative to protect my house from
woodpeckers.
