Mosquito Buzz to rid Loiterers
The problem of undesirable vagrants hanging out in places like stairwells of parkades is being tackled with Mosquito, a sound-device that emits a high-pitched unpleasant buzz.
In our Winter 2008 NOISE-Letter on page 5 we reported of a German innkeeper in Osnabrueck, who had a Mosquito installed with success. Locally, there is one in operation in the north-east stairwell at lot #2 of the City’s parkade, at 150 W. Pender St. in downtown Vancouver. It ostensibly had its expected effect within 24 hours. Also, the City of Castlegar (S.W. British Columbia) introduced the Mosquito last year. It was installed outside a bar to disperse bar patrons after closing time. They intend to purchase two more to keep people away from the skateboard park at night.
On the one hand, we want to get rid of the noise and other disturbances caused by many stragglers; on the other hand, we don’t want the deterrent device to bring on new problems.
At www.MosquitoGroup.com there is information posted about the sound levels and some of the effects. Following is a part of it:
How loud is the Mosquito? The Mosquito MK4 has been designed to run at 5 dB above background noise levels. This is done by using an on-board AGC system that measures the ambient noise and adjusts the sound output level accordingly. A comparison of the noise emitted by the three Mosquito models with common everyday sounds is as follows:
- A whisper – 15 dB
- Normal conversation – 60 dB
- Mosquito Mark 4 Standard – 85 dB
- A lawnmower – 90 dB
- Mosquito MK 4 Maximum Volume (M100) – 100 dB
- A car horn – 110 dB
- A rock concert or a jet engine – 120 dB
- A gunshot or firecracker – 140 dB
A Google-search for Mosquito Canada brought up the same webpage as above, albeit with a bit different information, excerpts of which follow below:
The new Mosquito MK4 Multi‑Age now has two functions. Either set the device to 17KHz to disperse groups of troublesome teenagers, or set it to 8 KHz to disperse people of any age from areas where loitering can be an issue, such as subway terminals, car parks or any areas where people feel insecure at night due to other people loitering in the shadows etc.
- Takes effect within a few minutes
- Can be activated by timer, remote control or PIR
- Increased max. range to 40 m (130 feet)
- 2 frequency settings: one for youth and one for people of any age
- 4 step volume selection
- Audible beep on/off
- 20 minute auto cut‑off
- Additional chipset for continuous running available for specific applications
- Built in PIR activation timer control

Olympic Noise for 2010 Winter Games
Sporting events have been getting progressively louder over time, and Olympic games are no exception. In February 2009 the Vancouver Olympic Organising Committee (VANOC) urged the public to make lots of noise on the occasion of the one-year countdown to the 2010 winter games. This summer Vancouver city council voted to amend a number of bylaws, including the Noise Control Bylaw #6555, to allow this Olympic noise with impunity.
More pre-Olympic noise comes from the sky, as CF-18 fighter jets and other aircraft are involved in Norad’s training exercises
leading up to the games. While these jet overflights may be relatively seldom, ever more small air-craft and helicopters drive up the cacophony considerably. Add to this all the increasing motor-vehicle traffic on the ground and water, and we will get noise levels of Olympic proportions.
Interestingly, VANOC is not listed in the Vancouver telephone directory. Their web-address is www.vancouver2010.com/

Skunks know best
Recently, an acquaintance of mine was very agitated after finding that a family of six skunks had made their home underneath the floor of the garden shed at the back of her property. After contacting the Animal Control agency, she was informed that it would cost about $1000 to relocate the skunks safely to another location.
Dismayed at the cost, she consulted the Internet for alternatives. Here she discovered a new approach which was completely free! Skunks, like most animals, do not like loud noises, so it recommended using a portable radio turned up to a high volume to
disperse them. Subsequently, my friend placed a radio on the floor of the shed where the skunks lived.
After listening to the loud noise for one night, the skunks decided to leave. The next morning there was no sign of the former garden residents. They were all gone!
Unlike their human counterparts, the animal world has some sense when it comes to loud, intrusive noise. Fortunately, they have not become conditioned to unhealthy sound levels. Clever skunks!
