<\/i><\/i><\/span>MORE INFORMATION<\/span><\/a><\/h4><\/div>\nThe Diamond Bell\u00ae DB-03A Repellent is an effective solution to keep spaces free of mice and roaches. Designed for continuous use, this device emits adjustable ultrasonic waves that affect the nervous system of these pests, driving them away from the protected area. It is a safe, chemical-free option, ideal for homes with children and pets, as it uses no toxins and emits no odors.<\/p>\n
DB ultrasonic technology affects roaches and rodents by generating high-frequency sound waves, imperceptible to humans, that interfere with their sensory and communication systems.<\/p>\n
The ultrasounds disorient roaches, disrupting their ability to navigate and communicate, making it difficult for them to adapt to the environment. This drives them to leave the treated area.<\/p>\n
Additionally, ultrasonic frequencies create stress and discomfort in rodents, affecting their natural behavior and forcing them to seek a quieter place to shelter.<\/p>\n
In both cases, the ultrasounds create a hostile environment, significantly reducing the presence of these pests without using chemicals.<\/p>\n<\/div><\/div><\/div>
<\/i><\/i><\/span>FREQUENTLY ASKED QUESTIONS<\/span><\/a><\/h4><\/div>\nCan the DB Ultrasonic Technology of this Anti-Mice and Roaches device affect: babies, pregnant women, children, or adults?<\/strong>
No, the technologies used in Diamond Bell products do not cause any harm to people or animals.<\/p>\nIs it safe for pets?<\/strong>
Yes, the device is safe for pets and people, as it does not use chemicals or emit odors. The DB-03A electronic repeller is designed to be highly effective against rodents. However, if you have pet rodents at home (such as hamsters or guinea pigs), it is recommended not to place them in the same area of action as the device, since the ultrasonic frequencies may cause stress and discomfort.<\/p>\nDoes it work with all types of roaches?<\/strong>
Its effectiveness has been tested with German Cockroach (Blattella germanica) and American Cockroach (Periplaneta americana), which are the most common and resilient species.<\/p>\nDoes it work with all types of rodents?<\/strong>
It is designed to affect common house mice (Mus musculus), although it can impact other types of rodents as well.<\/p>\nWhat is its lifespan?<\/strong>
Its lifespan is unlimited.<\/p>\nDoes it require refills?<\/strong>
No, it does not require refills, which represents significant economic savings.<\/p>\nIs it effective for large areas?<\/strong>
This model is ideal for areas up to 25 m\u00b2. For larger spaces, using multiple devices is recommended.<\/p>\nCan I place other Diamond Bell\u00ae models in the same room?<\/strong>
Yes, our products are fully compatible.<\/p>\nHow long does it take to take effect?<\/strong>
The best results are observed after 1 to 3 weeks, as mice and roaches, although stunned from the first moment, initially resist leaving the area.<\/p>\nWhy do I see more roaches at the beginning of using the anti-mice\/roaches device?<\/strong>
In the first days, roaches that were hiding may come to the surface. This indicates that they are leaving the area.<\/p>\nThe roaches don\u2019t go away<\/strong>
Keep in mind that among different roach species, German roaches are the most resilient, and their removal may take longer than usual.<\/p>\nCan I combine it with the use of poisons?<\/strong>
It is not advisable to use them simultaneously, as poisons attract while the anti-mice\/roaches repeller pushes them away, making the effects opposite.<\/p>\nWhat should I do if the LED indicator does not work?<\/strong>
Check that the anti-mice\/roaches device also does not work in another outlet, and after confirming, contact Diamond Bell Technical Support.<\/p>\nI hear a slight sound when plugging\/unplugging<\/strong>
This is normal and lasts for a moment. It is an indicator that the device is working correctly.<\/p>\nDoes it require any maintenance?<\/strong>
No, the device does not need maintenance or refills; it only needs to be connected to function.<\/p>\n<\/div><\/div><\/div>
