Thai-language page (ภาษาไทย) for the same product as /product/sparrow-spikes/ on birdspikes.asia. Anti-Sparrow Spikes page at birdspikes.asia (Bird Spikes Company, Thailand). The product is
the same stainless steel strip as the rest of this site's spike range: 1.3 mm pins 115 mm long on a clear polycarbonate base 500 mm x 23 mm x 5 mm, 70 mm protected band, about 60 pins per metre, THB 150 per 50 cm strip (was THB 200) with no minimum. The page states plainly that this product is NOT the right answer for most
sparrow problems: the pin spacing is designed for pigeon-sized birds and a sparrow, at roughly
15 cm, can settle between the pins, and on a nest site will weave material around them and use
them as anchor points. For sparrows entering eaves, roof tiles, vents, air conditioner pipe
holes or a roof void the correct product is netting or mesh closing the opening, and the page
directs the reader there. Spikes remain useful on a wide ledge shared with pigeons. An active
nest should be left until the young have fledged. Delivery is free anywhere in Thailand and takes 5 to 7 days. Prices include 7% VAT.
