Review: Works well if used correctly - My next door neighbour is an animal lover and has always left seed out to feed small birds. Recently she has taken to leaving larger amounts of food out and has attracted seagulls, crows and feral pigeons. Unfortunately she isn't the most approachable person, so I decided on buying an electronic scarer rather than having any confrontational visits with her. To be honest, the reviews of all the sonic and ultrasonic scarers are very mixed and I was not 100% sure this one would actually do the job, but I thought I'd try one and see for myself. I've had it working for 4 days now and it does seem to be doing a good job. I didn't particularly want to scare the smaller birds away from eating in the tree next door, but did want to get rid of the large birds which spend hours on the ground fighting over the dropped seed and then take off and cr*p all over our washing, so I placed the unit directly on the ground facing the tree at a distance of about 5 metres away. I have the audible sonic sound set to "off" and the ultrasonic pitch set at the higher end of the "birds" setting, during the daytime only (off at night). The results are quite obvious and exactly what I wanted to achieve. I've switched it off a couple of times , just to see whether the birds return, and they do come back within a few hours but leave as soon a s it is switched back on again. The small birds such as sparrows still hang on the feeder in the tree but the larger birds absolutely WILL NOT go near the tree on the ground. We've watched pigeons walk towards the tree and suddenly stop still, then fly away without attempting to get close to the seed. Seagull have not even bothered to land since the unit has been active. It hasn't affected the nearby nesting birds and their young, which still tweet in the morning while the parents are collecting bugs from further up the garden, so all seems to be good in that respect.The neighbour has obviously noticed the unit sat on the ground, but has not mentioned it, so that all seems good too! I may be lucky in the fact that I have worked with sonar and so I have a basic understanding of how sound-waves work and are affected by various conditions. I would say that to get best results, although the unit sends a 170 degree signal from the front,it still needs to be facing directly towards the area that needs controlling, it must have no obstacles in the range between the unit and the target and that it will be less effective when it is raining. Thoughtful and careful siting of the unit will give much better results. The photo shows the unit sited next to a garden ornament, facing the tree at a distance of about five metres from the problem area. UPDATE August 2016: I've had this product working in the back garden for 3 months now and here's what I've noticed: 1. It works best if you either change the ultrasonic frequency every week or two, or if you set it to scan through the complete range. 2. It may not ALWAYS be the birds that are the issue, but the people who attract them by feeding them. So, as far as I'm concerned, the problem has now been completely eradicated by setting the audible noise at a level that actually became so annoying to the unapproachable neighbour it forced them to come round and agree to move the bird feeder as long as I turned the noise off! Agreement was reached and the problem has gone. Best money I ever spent! Review: Just don’t waste your time! - Don’t waste your time, same issues as other poor reviews, first one didn’t last 24 hours before it stopped working and thought maybe its just a defective one so sent back and ordered again, the second one came defective straight out the box, even with the first one that worked for a short time the foxes would sit infront of it unfazed! The back cover is also poor and doesn’t secure properly! Just don’t waste your time with this, oh also forgot to mention the first one sent had a screw that had been driven too far from the inside that it came out the front corner and would stick into my hand and fingers, I’d give no stars if I could ## Features - ADVANCED DUAL TECHNOLOGY: Uses powerful ultrasonic frequencies and an optional sonic alarm to create an "unfriendly zone." The built-in Night Time Scanner and Infrared Motion Sensor detect movement up to 5500 sq. ft., triggering the device only when pests are present. - LARGE ANIMAL DETERRENT: Engineered to repel outdoor intruders like Deer, Raccoons, Skunks, Rabbits, Foxes, and Geese. Note: This high-intensity outdoor unit is designed for larger yard pests and is not intended for indoor rat or mouse control. - 3-MODE SMART PROTECTION: Switch easily between Motion Sensor, Constant, or Continuous Sweep modes to match your pest pressure. The infrared sensor detects movement, activating the 24-hour Day/Night scanner exactly when needed for maximum coverage. - IPX4 WEATHER-RESISTANT AND DUAL POWER: Built for durability in temperatures from 14°F to 122°F. Features an IPX4-rated housing designed to withstand splashes and light rain; for best results and longevity, mount under a slight overhang or avoid direct vertical downpours. Includes a 10mtr AC extension cord for constant power, or runs on 4 C batteries (not included). - PRO-TIPS AND INSTALLATION GUIDE: Prevent animal habituation by rotating frequency settings every 2-3 weeks. For best results, install one unit every 5000 sq. ft. with a clear line-of-sight, as ultrasonic waves cannot penetrate solid objects like fences or dense walls. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00T86NCSE | | Best Sellers Rank | 73,750 in Garden ( See Top 100 in Garden ) 521 in Pet & Wild Animal Control | | Customer Reviews | 3.4 3.4 out of 5 stars (441) | | Date First Available | 13 Mar. 2015 | | Item model number | - Yard Sentinel Ultrasonic | | Manufacturer | Aspectek | | Part number | HR1313 | | Product Dimensions | 24.38 x 11.94 x 17.53 cm; 544.31 g | ## Product Details - **Brand:** ASPECTEK - **Colour:** Green - **Style:** Garden - **Product dimensions:** 17.5L x 11.9W x 24.4H centimetres - **Item weight:** 0.74 Kilograms - **Number of pieces:** 1 - **Is electric:** No - **Target species:** Rat, Mouse - **Unit count:** 2.00 2 - **UPC:** 805939021016 878312001790 ## Images ![ASPECTEK Yard Sentinel Ultrasonic Animal Repeller, 5500 Sq.Ft.

The sound goes out about 70 square feet. However, the sound only comes out of the front of the device with a radius of about 150 degrees to the sides, so you can avoid aiming it at the public space. **Q: How do you attach it to a wall ?** A: It has two holes on the back which will hang over screws put in the wall. It is quite secure but can easily be lifted on and off when necessary. **Q: Can i put this on a table under a tree. i’m trying to stop pigeons shitting on the table. should i put it in a plastic bag. does wind affect it?!** A: The unit is weather proof, so I would not use a plastic bag, the bag would also weaken the sensor, thus defeating the desired effect, you would have to prevent it from been blown over in a strong wind, maybe stick on table with some double sided sticky tape or blue tac, then it should be fine, read the manual for your desired output of signal, & adjust accordingly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well if used correctly *by P***R on 23 May 2016* My next door neighbour is an animal lover and has always left seed out to feed small birds.

I have nothing against cats per say, others that they are using my property as an official toilet . Access to the battery case and controls are difficult, as one has to wrestle the unit for some time and pain to close the back of the unit. This is a design fault and could have been better handled, by making it a screw lid rather than a badly designed clip-on. The settings to set up the unit to the sound level of specific animal one wishes to discourage are definitely made for the American or Canadian market. The It is not clear as one is moving the dial from one type of critter t the next that those animals in the lower range will not also be affected, rather than a specific mammal as per the dial, e.g. cat/dog and not also bats. Here in the UK bats are under protection, sa they are on our red book list. I also find it very expensive, when compared to other units. In defence it does have additional feathers such as dialling the specific creature. Other units one can also dial up different sound frequencies, but no clear description. It is very battery hungry, and they use C class batteries, which are not common use these days, which leads to anoretic high maintenance expense. ## Frequently Bought Together - ASPECTEK - Yard Sentinel Ultrasonic Animal Control, Pest Repellent for Rat, Mice, Cat, Dog, Deer with Motion Sensor & Intruder Alarm (UK PLUG) - Duracell Plus C Batteries (4 Pack) - Alkaline 1.5V - 100% Life Guaranteed - Reliability For Everyday Devices - 0% Plastic Packaging - 10-Year Storage - MN1400 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/52448772-aspectek-yard-sentinel-ultrasonic-animal-repeller-5500-sq-ft-coverage](https://www.desertcart.kr/products/52448772-aspectek-yard-sentinel-ultrasonic-animal-repeller-5500-sq-ft-coverage) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-11-14*
