Now we need to talk about chemical deterrents. These work great but have one major flaw. The rain will wash it away. This means you have to reapply or hire someone to reapply after every storm. This isn’t very cost effective if you live in an area that has heavy rain. You may want to use this in summer then use another deterrent in the fall and spring. Some come in a concentrate that you mix, and others come already made with a sprayer.
The Liquid Fence uses Methyl anthranilate which is the grape flavoring in our food. Geese really don’t like the taste of it.
