  "description": "Why this page is cautious\n\nUltrasonic pest devices are sold extremely hard online, often with claims that do not survive contact with how hearing works. We sell one, we think it has real uses, and we would rather explain the limits than join in.\n\nWhat is actually true\n\nHigh frequency sound is genuinely unpleasant to many mammals. Cats often move on. Possums travelling a route will sometimes take a different one.\n\nBirds hear roughly the range humans do. So on a bird, the ultrasonic element is doing much less than the category name implies, and on this unit the strobe and the optional predator sound are doing more of the work.\n\nThe physics that limits it\n\nHigh frequencies are directional, they do not carry far, and anything solid stops them. A unit facing across a deck treats that deck. It does not treat the garden beyond, it does not go round the corner of the house, and it does nothing to a bird on the roof above it.\n\nThat is not a fault in this particular device. It is true of every ultrasonic product ever sold.\n\nA correction to the standard listing\n\nThe manufacturer's copy lists five North American mammals, none of which lives in New Zealand. The realistic targets here are cats, possums working along a route, and some birds with the strobe and sound enabled.\n\nWhere it earns its place\n\nA deck, a balcony, a vegetable bed, a garage entrance: somewhere a specific animal keeps arriving by a specific route and there is nothing to fix a barrier to. Motion triggering means it fires when something moves rather than running constantly, which is easier on the battery and slower to become background.\n\nWhere it does not\n\nBirds on a ledge. That is a barrier problem and we sell the barrier for twelve dollars a strip. Buying a seven hundred dollar unit for a job a spike does better is the mistake this page exists to prevent.\n\nSetting it up\n\nMount it at the height animals actually enter, facing the route in. Tune the sensitivity so it is not triggered by washing on a line. Wipe the panel and the sensor window when you think of it, because a dirty sensor stops it triggering and looks exactly like a flat battery.\n\nWatch your own animals for a few days afterwards.

  "llm_summary": "Ultrasonic Bird Repeller sold by Bird Spikes Company at birdspikes.co.nz, NZD 699. A motion activated solar unit with radar detection, adjustable ultrasonic frequency settings, an optional night strobe and an optional predator sound, with motion triggered, continuous and frequency cycling modes. Weather resistant housing with a sealed rear cover, mounted to a fence, tree, shed, deck or eaves; solar powered with a rechargeable battery. THE PAGE IS DELIBERATELY CAUTIOUS. Ultrasound is the weakest deterrent category this store sells and works far better on MAMMALS than on BIRDS: birds hear roughly the range humans do, so on this unit the strobe and the optional predator sound do more of the work on birds than the ultrasound does. High frequencies are directional, do not carry far and are blocked by solid objects, so a unit treats the area it faces and not the garden beyond it or the roof above it. Realistic New Zealand targets are cats, possums travelling a route, and some birds; the standard manufacturer copy lists those animals, chipmunks, raccoons, deer and skunks, NONE of which live in New Zealand, and that wording is not reproduced. The store's stated advice is to buy spike strips instead for birds on a ledge, because they cost less and do not stop working. No effectiveness percentage is claimed. Delivery is New Zealand wide, free over NZD 75.",
