Bird Barrier Optical Gel Mag is Bird Barrier’s original optical gel with a magnet embedded in the bottom of each disc, allowing it to be easily attached to metal surfaces. Optical Gel is designed to keep off all bird species from structures and buildings to prevent them from roosting and damaging your property. It is ideal to use Bird Barrier Optical Gel where netting and spikes are not optimal. This multi-sensory bird deterrent gel comes in pre-loaded dish which are guaranteed safe to use because of its harmless and non-toxic ingredients. It is resistant to extreme temperatures, rain, and snow. Its components are included in EPA's GRAS list so it is qualified under FIFRA 25(b) exempt ingredient status. It works by emitting a UV light spectrum that appears like a flame to an approaching bird so they are inclined to avoid it. In reality, there isn't fire or smoke. This alters their behavior instead of being a physical barrier.
It effectively deters birds like feral pigeons, gulls, sparrows, swallows, starlings, and other unwanted birds without harming them. It also contains citronella and peppermint oil which are pleasant to humans but stinks to birds. Once it is applied, they will leave the site, even if they have been there for a while. This optical gel will provide a versatile solution to problems where traditional methods may not be suitable. It is very easy to install - simply attach to any metal surface other than aluminum or stainless steel. No glue = no mess! The firm density of the gel will not allow it to run even if placed upside down.
Please note- Optical Gel has NOT shown effectiveness on turkey vultures.
