Hi.. We have very tall trees that have grackles roosting in them. Can we use a power sprayer for applying the 4-the-birds liquid? Thanks, Ann.
Though 4-THE-BIRDS would be a great treatment option, you won’t be able to spray it through any type of power spraying system I’ve ever seen. The reason is that the viscosity of the product is just gooey and thick enough to cause most pumps to clog. And though you can apply it with a standard PUMP SPRAYER, using a paint brush is just as effective and in most cases more efficient.

Now if you feel the trees in question are too high to reach or that the area involved is too big, consider the ULTRA SOUND DEVICE. Specifically the 4 speaker unit. This device is ideal for large areas and quite effective on repelling grackles. One unit can easily cover 5000 sq/ft and once the birds start hearing the sound, they’ll typically move away and stay away from an even larger area.
