Deramax-Bat - Ultrasonic bat scarer (repeller)

Use of the Deramax-Bat scarecrow

Product version: 04/2022 (on sale from 15.5.2022). Change from previous version: extending the range of the scarecrow and solving complete noiselessness.

The Deramax-Bat is designed for use as a bat scarer (repeller). It generates specific ultrasonic signals that are very unpleasant for bats, so that after a short time they leave the protected area and seek a new refuge outside the area protected by the scarecrow. The generated ultrasonic signals have an automatic change of frequency in a given range so that bats do not get used to the signal and at the same time an automatic change of power (sudden change of power), which contributes to the higher efficiency of this type of scarecrow. The operation of the device is completely ecological, without the use of chemical means.

Deramax - Bat is a bat scarer and does not affect e. g. domestic cats, dog or horse. It is not suitable to keep hamsters, guinea pigs, laboratory mice and rats in a protected area.

Features of the Deramax-Bat Repeller

The Deramax-Bat scarecrow generates specific ultrasonic signals that are very unpleasant for bats, so that they leave the protected area after a short time. The built-in automatic frequency change function ensures that pests do not get used to the device's signal. The built-in automatic power change function contributes to the higher efficiency of this type of scarecrow.

Target pest group: bat
Scarecrow type: ultrasonic (completely noiseless). Automatic change of frequency and power.
Effective range (outdoors and without reflecting surfaces): Range up to 18 metres at 180 degrees. Effective range indoors: 230 m2.
Impact on humans: no impact
Effect on pets: the device affects hamsters, guinea pigs, laboratory mice and rats.

The Deramax - Bat Repeller (Repeller) has a very economical operation.
The Deramax - Bat is a bat scarer, but can affect e. g. pet hamsters, guinea pigs, laboratory mice and rats. However, there is no need to deal with any special measures of pets. It is quite sufficient if the pet is free to leave the area protected by the device. Thus, the bat repellent will not harm your pet, only the animal may avoid the area. However, always ensure that the pet has the opportunity to leave the protected area, and this type of scare must never be used on an animal confined in a cage.

Basic features of the Deramax - Bat:
High performance - Automatic frequency change - Automatic power change - Very wide effective angle of attack - Safety - Water and dust resistant

NOTICE ON POWER SUPPLY: This scarecrow requires a mains power supply (socket adapter) for its operation, which is not included in the scarecrow delivery, but must be added separately to the basket. Once you add the scarecrow to your cart, you will automatically be presented with the "Recommended purchase" menu, where you can add the appropriate Deramax-CN01 power supply (item code: 1000) directly to your cart. A suitable Deramax-CN01 mains power supply (item code: 1000) is also displayed on this page (below the text) as "Connected products", or you can find it in the product category "Power supplies, batteries & accessories".

WHY IS THE NETWORK POWER SUPPLY NOT INCLUDED IN THE SUPPLY AND PRICE OF THE SET: Because we do not consider it appropriate to force customers who do not use this power supply (it powers the scarecrow from a 12 V battery, a photovoltaic system, a power supply in a switchboard, etc.) to pay for it in the price of the "scarecrow + power supply" set. So who does not need the mains power supply, does not need to pay for it unnecessarily and then just as unnecessarily throw it away.

Safety and comfort of operation of the Deramax - Bat

Deramax - Bat operates in the ultrasonic range, does not disturb its surroundings with annoying noise and is completely silent. Of course, this scarecrow meets the legal limits set for the maximum ultrasound level, but our internal rules go beyond the applicable laws and take into account medical scientific work and recommendations of international medical organizations in connection with the use of ultrasound signals, thus ensuring the complete safety of the users of this product.

Range of effectiveness of the Deramax - Bat Scarecrow

The range of effectiveness of this bird scarer is at a distance of up to 18 metres at an angle of approximately 180 degrees. The scarecrow not only has a high power but the special design of the device ensures that a very wide effective angle of 180 degrees is achieved, while even at the limit of the declared angle of incidence (i. e. outside the main direction of signal emission) the scarecrow still generates at least 80% of the declared sound pressure level.

Any number of scarecrows may be placed in one location and their signals shall not adversely affect each other in any way. On the contrary, it is common to use multiple scarecrows to protect especially larger or more rugged areas, as a larger number of scarecrows (repellers) installed in one location means a significantly higher overall effectiveness.

WARNING: In some countries certain bat species are protected, or all species of wild bats are protected. We therefore recommend that you check whether and which bat species and which sites are protected in your country. It is often not only the animals themselves that are subject to legal protection, but also the bat's habitat from both destruction and disturbance.
