Mosquito MK4 (Anti-Loitering device)
If you have problems with teenagers loitering near your property, causing criminal damage, putting off customers or abusing your customers and staff, the Mosquito MK4 is the most effective method of putting a stop to it. We have sold thousands of our devices worldwide to police forces, local authorities, chain stores, independent shops, schools and private individuals with great results.
Antisocial behaviour is one of the fastest growing problems in society and unfortunately there is little the police can do to prevent it - take back control with the Mosquito MK4.
How does it work? Is it legal? Is it harmful?
Our customers often have many questions about Mosquito devices - we are of course more than happy to answer any questions that you may have prior to purchase. Please view our 2 videos below for product information.
