Last year, I had a family of sparrows nest just above my front door. Their mud nest left a mess on my patio, not to mention bird crap from both the adult sparrows and eventual babies, which was most irritating when packages were set directly on top of this mess.
After applying the gel, this customer saw the change immediately.
The day after I applied it, I noticed the sparrows visiting once again, but they would only fly near the corner they favored for nesting and then retreat. They stuck around for another day or two before leaving for another nesting site.
Another satisfied customer!
