This product did not help or do anything at all to deter birds from flight and perching on the eaves on my balcony. It smells decent, although there is no effect on birds. For this reason, I do not recommend this product.

It didn't work even when I mixed it stronger

We were very excited to receive/purchase this item for hopes of it ridding us of our duck problem--we have tried several times mixing and spraying the solution and they ducks still come back. We have followed the manufacturers direction for proper mixing/spraying and the ducks were still there. The next several times we increased the strength of the solution to make a stronger product but to no avail the ducks stayed. I did a lot of research for humane eco friendly ways to rid your yard of waterfowl and read many positive reviews about this product however at this point-from our personal use -we don't find this product to be effective and feel that we wasted our money.

Tried this stuff and it just seemed like to make a mess ans stain certain parts of my house and did nothing to keep the birds away!!

ABSOLUTELY does not work. Went above and beyond direct use. Including presume washing and bleaching of area. Doubled the recommended application amount. Birds returned in 3 hours without a care in the world.
Do not buy this product it is a total waste of time and money. I am a general contractor and tried this for a client, not only am I out the money for this product but also labor. Worse I sure my customer is sceptical of all we do now.
