This is totally incorrect our product is a game-changer to the traditional practices of bird control. we have removed the unwanted birds of the structures with pest control operators here and around the world when spikes, nets, and trapping failed in outdoor structures and indoor facilities. simply apply PIGNX BIO-REPELLENT BIRD GEL onto the surface where the birds are congregating or roosting (make sure that the surface is nonporous. if it is porous use a silicone gel barrier to seal the surface. apply the PIGNX BIO-REPELLENT BIRD GEL on the silicone gel) and the birds will land onto the gel and begin dancing on it because they don't like the gel and they will spread the gel on to their body and when they fly away they retract their legs onto their body and the PIGNX BIO-REPELLENT BIRD GEL will get into their butts and make them uncomfortable and then they will fly from one area to another and spread the PIGNX BIO-REPELLENT BIRD GEL for you making those areas a no bird zone. They will do these for 2 to 3 days eventually making the building or structure a no bird zone. Sometimes you will find them walking on the ground and if its indoors you can escort them out. And if it's outdoors they will fly up to 2.1 miles away. (we actually followed them to see where they went) remember you need to apply enough PIGNX BIO-REPELLENT BIRD GEL to all the areas they are roosting or congregating in a thick 1/2 inch bead with the tips that we provide. PIGNX BIO-REPELLENT BIRD GEL has never failed as long as you apply enough gel for the corresponding bird pressure. High profile areas such as PLANET HOLLYWOOOD, THE PLAZO HOTEL, THE VENETIAN HOTEL, THE COSMOPOLITAN HOTEL, THE WINN HOTEL, THE ENCORE HOTEL. JW MARRIOT HOTEL, THE TESLA FACILITY, food storage facilities, food processing facilities, Kroger Supermarket, Dodger Stadium, and Angel Stadium to name a few sites PIGNX BIO-REPELLENT BIRD GEL was applied.
