Teen delinquency is a challenging problem that many businesses face. Businesses have plenty of concerns, including anti-social loitering, thievery, and even breaking and entering. The problem, however, is that as a business owner, you cannot touch them, harm them, and may even struggle to bar them from entry if they push through.
That’s why prevention is key.
After seeing a steady decline, we’re now experiencing a two-year increase in teen crime. Between 2022 and 2023, youth-related crimes increased by 13%. When broken down to types, property damage saw a 13% increase. To reduce loitering and related crimes, it’s important to invest in non-harmful, legal, and effective solutions like one of these top 3 anti-loitering devices.
1. The MK4 Mosquito Anti-Loitering Device
The number one solution that businesses are turning to is the original security sound deterrent, the MK4 from Mosquito Loitering Solutions. This device has multiple settings, allowing you to swap between two frequencies to specifically deter young people, or, if you also want to stop rough sleeping, an all-ages setting.
Connect your MK4 to motion sensors, cameras, or timers, and either automatically or remotely release a high-frequency noise designed to annoy teens into leaving without a hitch. It’s tested and approved for use on humans, so you can relax knowing your deterrent is safe, but effective for both humans and wildlife.
The Mosquito anti-loitering device is ideal as it allows you to deter anti-social behavior remotely, and without any direct confrontation, allowing all types of businesses, including small ones, the ability to better protect themselves.
2. The BCT017 Brocott
The Brocott BCT017 (which may be the same as the Best Ultrasonics Sentinel device, under a different company) is another common recommendation as an anti-loitering solution. It uses a 16.5KHz frequency that’s ideal for irritating young people congregating around your property. It also comes with a wall mount and mains converts, making it easy to set up and direct the noise directly where problem areas exist.
It also boasts a frequency range of 50m, though you do need to be careful here. You may end up harassing your residential neighbors’ children and pets just as much as you do the teens loitering on your property. The 50m range, then, is better suited for larger properties with lots of land.
3. Long Range Ultrasonic High Power Generator ABC Fire & Security
The long-range high-power generator is another anti-loitering device available on the market. It boasts the longest range (100m), though it only offers a single frequency, making it only effective against young adults, not all types of loitering. After testing, it also appears that the unit is actually a rodent scarer from Kemo Electronics, which could expose your business to liability if people experience headaches and other issues.
The longer, louder frequency it emits, however, makes it ideal for businesses on large plots, like those with parking lots, warehouses, and other industrial sites. If you’ve been dealing with teen parties, graffiti, or other teen-related delinquency, then this unit, alongside others like a motion sensor, camera, and automated messaging system, might help you remotely and automatically protect your business.
