Before & After The Mosquito®: Breaking the Loitering Cycle
Over 20 years of real world field deployment across the United States and Canada proves one truth: calling the police or hiring reactive guards drains your operational budget without solving the root problem. Autonomous deterrence does.
Fed Up With Teens Loitering Outside Your Business? Homeless Encampments? Vandalism & Antisocial Behavior?
The Mosquito® Anti Loitering Alarm is North America’s leading autonomous solution to disperse unwanted gatherings safely, harmlessly, and without putting your staff at risk of physical confrontation.
Why Choose the Mosquito® Anti Loitering Alarm
Engineered specifically to disperse chronic loiterers, antisocial gatherings, and rough sleepers in under 15 to 20 minutes without physical confrontation. Explore the industrial grade components that set the world standard in autonomous acoustic security.
Dual Frequency Acoustic Sweeping: 30m to 50m Range
Select between two field tested acoustic settings: Teen Mode at 17.5 kHz audible exclusively to under 25s, dispersing youth gangs while remaining completely inaudible to paying adult customers; and All Age Mode at 8 kHz for clearing chronic rough sleepers and encampments. Delivers an effective acoustic sweep of 30 meters Teen Mode up to 50 meters All Age Mode with 10 micro adjustable volume steps.
Vandal Proof Galvanized Steel Security Enclosure
Because deterrence units operate in high risk perimeter hotspots, every Mosquito MK4 is protected by an ultra heavy gauge, galvanized steel security cage. Specifically engineered to withstand blunt force hammer blows, thrown rocks, heavy vandalism, and attempted theft while allowing acoustic dispersal waves to radiate freely without muffled distortion.
60° Directional Lock Angle Aiming Bracket
Includes heavy duty, multi axis industrial mounting brackets allowing 60 degree articulation. Locks the acoustic deterrent cone precisely onto doorways, recessed storefront alcoves, emergency exits, and parking stairwells, eliminating sound spill into neighboring properties or upper floor residences.
IP65 Extreme Climate Resilience: from minus 40°C to +50°C
Hermetically sealed in a weather resistant, UV stabilized polymer housing engineered for extreme North American climates, from sub zero Canadian winter blizzards of minus 40°F and minus 40°C to intense summer heat up to +120°F and +50°C. Waterproof, dust tight, and maintenance free for 10+ years of 24/7 service.

The Mosquito has been highly effective. Prior to the install, we had constant loitering and vandalism. Now, we have seen a 95% to 98% decrease in activity and incidents.
I decided to purchase the Mosquito device because tenants of mine had been hounded by noisy, drunken and malicious youths for many years. It worked perfectly last night.
The Mosquito worked perfectly. I got it hooked up just in time for some kids to show up. After I turned it on, they left shortly. Outstanding device for loitering prevention.
