驅雀膏的原理是令表面變得黏滑，令雀鳥不願意降落在已處理表面，即使降落了亦會因為產生不舒服的感覺而選擇飛走。久而久之，雀鳥便不會再飛回同一個地方。美國製造，有效期達一年，無毒、無色、無味，簡單易用。
The bird proof gel makes any surface slippery and sticky, there birds will no longer want to land and hang out on that area because of the discomfort. Over time, birds will not return to the same area. Made in the US, capable of lasting for a year, no toxin, no color, no smell, very easy to use!
