The Sentinel MKII Ultrasonic Pest repeller is weatherproof and designed for indoor or outdoor use. If using outdoors, the plug-in mains power adaptor MUST be plugged into a mains socket inside a building and never exposed to dampness or moisture. Do not remove the front cover of the unit as this will damage the weatherproof seal.

The Ultrasonic repeller is a fully adjustable, self contained module with frequency ranging from approx. 8kHz to 40kHz. At least 50% of this spectrum is in an audible frequency range and can be heard by humans, but the unit can be adjusted to a higher frequency to generate a silent Ultrasonic tone. Most of the successes reported with deterring birds, Pigeons, Mice, Rats, Cats, Dogs, vermin and pests in general have been achieved with unit set to the higher ultrasonic frequencies (silent), so it is sometimes best to experiment with the setting as many different local environmental factors and animal breeding / feeding cycles can effect the overall effectiveness. The Sentinel modules are not designed to scare animals or birds, but rather to create and maintain an environment that is uncomfortable which can cause them to move on and avoid the area.

The ultrasonic repeller can be mounted in a safe spot on a wall or fence post etc, a few feet above the ground. Ideally, the repeller should be at approximately the same height where your particular target pest habits. For example, if you are trying to repel birds on a roof, or Pigeons in a tree, the unit should be higher off the ground. But often you will need to compromise and the modules are supplied with an adjustable mounting bracket. Once set up and pointing in the general direction, the module can be adjusted on its bracket and pointed to the effected area for best results. To avoid rain water from gathering in the speaker housing and causing possible damage, pointing the module upwards should always be avoided with vertical adjustment not exceeding 10 degrees above horizontal. If mounting in warehouse, remember that girders and pillars will block the sound, so it is better to have no obstructions directly in front of the unit.

Please pay attention to the fact that ultrasonic sounds travel in straight lines (similar to that of torch light). Therefore the module should be positioned in such a way that the loudspeaker points directly at the area to be protected. Obstacles (e.g. cupboards, shelves, fences, trees and hedges) cast “shadows”, the ultrasonic sound behind these obstacles is considerably weaker, so line of sight is always the best option. The frequency can be adjusted by using the controller on the base of the casing. To change the position of the controller use a small screwdriver and twist the protruding adjustment screw carefully.

Adjusting the frequency.

If the controller is turned anti clockwise, the sound frequency will get lower all the way down to approx. 8.000 Hz and audible for human beings. The more you turn the adjustment screw in a clockwise direction the higher the sound frequency and from a certain point on, no longer audible for human beings. Every species of animal reacts differently to specific frequencies and this will have to be tested accordingly for best results.

For better results we recommend not to operate this ultrasonic device permanently but only to have it switched on during the hours that are of the most concern or to operate the device through a plugin timer set for the active periods.

The operating voltage of 12V d.c. voltage is supplied by the plug-in power supply and no other mains adaptor should be used. Every module has been tested carefully before dispatch, so if there are any concerns regarding installation or functionality please contact us for advice.

The pest are not going away: Ultrasonic sounds do present a strong annoyance for animals but it can occur in some circumstances that ultrasonic sound won’t repel animals. This may happen for the following reasons:

  • 1) The animals have to take care of their young offspring close to the ultrasonic repeller and they will not leave them despite the annoyance.
  • 2) There is a shortage of food in the area and it can only be found close to the ultrasonic repeller
  • 3) Adaptation to ultrasonic sounds. Some electronic appliances do also release ultrasonic sounds from high voltage transformers etc and animals may get used to them.
  • 4) If wild animals have left their scent marks in the area, then these animals will want to defend their territory and ultrasonic sounds may not have an immediate effect on them. In this case please clean the area where the animals have left their scent marks.

Ultrasonic Cat, Fox & Badger repeller with flashing LED strobe lights

Keeping unwanted Cats, Dogs, Foxes and Badgers out of your garden at night just got easier with the ultrasonic pest repeller / deterrent with twin flashing LED strobe lights. The battery or mains powered deterrent can be used in a loft, where there is no mains power supply, to get rid of squirrels. The animal deterrent uses ultrasonic sound to keep unwanted pests away from your property. It has a flashing strobe light that works especially well against nocturnal pests such as Foxes or Badgers and it is the bright, flashing LED strobe that will help get rid of Squirrels. The ultrasonic pest repeller has 2 different frequency settings, so play around and see which one works for you. Importantly, the repeller has an on/off switch so it doesn’t have to be on constantly (when you’re in the garden, for example).

The PIR sensor detects movement infront of the unit and activates the ultrasonic sound and the LED flashing lights.
