Using the Dissuader during daylight hours:

While the Dissuader is mostly ineffective outdoors in direct sunlight (it can be used effectively on cloudy days), it can still be very effective during daylight hours when used indoors to clear buildings such as warehouses, retail stores, and hangers.

How often usage must be repeated:

How often the laser must be used to control the targeted population depends on  species, location, and other dynamics such as alternative roosting sites and/or alternative food sources. Generally though,  after introducing the laser for sufficient nights to break the roost, the birds will leave and only send their "scouts" back periodically to see if the roost is now OK. Re-introducing the laser to these "scouts" will prevent the flock from returning. Most encouraging is that both penned and field-testing by customers and the USDA/APHIS/Wildlife Services have not shown any tendency of the birds to learn to ignore the laser. Indeed, some species appear to become more frightened of the Dissuader when it is re-introduced.

Non - lethal, non harmful bird control:

Part of the testing the National Wildlife Research Center conducted was the effect of high powered, 650nm wavelength, lasers on the birds targeted - their findings showed no physical harm to the birds or their vision systems even after many hours of uninterrupted exposure. Since the birds' eyes are coated with a film, or oils depending on species, to protect them from the UV rays of the sun, they appear to have a natural vision defense against the beam generated by the laser. Although mostly night-flying birds were a part of testing, this natural defense appears to also apply with diurnal birds or birds who are normally active in the day time.
