Efficacy

Authorised for use in the UK based on efficacy data from field tests. Data from a pigeon night roost study conducted over four years shows 100% efficacy. (Test methods specified by HSE.)
See test data on the efficacy and durability of Bird Free 

Case studies confirm that Bird Free:

• Remains effective for eight years without maintenance or replacement
• Is impervious to all climatic conditions (rain, snow, wind, etc)
• Will not melt or run in extreme heat
• Remains effective when discoloured by pollution
• Remains effective when covered by dust or dirt.

Bird Free retains efficacy in polluted environments

Bird Free emits UV radiation. This visual stimulus acts as a constant reminder to the bird that it should not return to a site treated with Bird Free. Because UV radiation is only blocked by solid objects, not particulates, Bird Free remains effective, even when covered in dust, dirt or rainwater.
