Our Eco-Friendly Goose Repellent Works in Two Ways:

  • It gives geese a visual warning — Because geese see the world in the ultraviolet spectrum, our repellent contains a UV marker. When the repellent is applied to your turf, the geese will see grass that’s purple in color and speckled in pattern. This serves as a threat to geese, and they learn to distinguish between treated and untreated turf. But to humans, the turf looks completely normal. Additionally, it causes no harm to the grass.
  • It causes indigestion — If the visual threat alone isn’t enough to keep geese away, the temporary after-effects will. When a goose consumes the grass treated with our repellent, it will experience digestive irritation within 20 minutes or so. It will bring no permanent harm to the goose whatsoever. They will refuse to eat any treated turf after they’ve experienced this stomach upset. Geese learn very quickly that it’s within their best interest to avoid treated turf. The geese will move on to a different location

Urban Deer

Deer can cause several types of problems in residential settings, from personal property damage and crop destruction to expensive car/deer accidents. The most common complaint is deer damage to vegetable gardens, fruit trees and ornamentals. It is not easy or cheap to keep unwanted deer away, and often the best solution may be a greater understanding and tolerance of deer. Custom West Pest Control can provide deterrant systems and professional exclusion exclusion methods to keep deer off of your property.

It was SO satisfying to watch the last few bats get evicted. Bye, felicia! This was the ONLY pest service who seemed SANE when telling us about the bats. others told us to LIVE HAPPILY with bats peeing and pooping all over our new home. No thanks!”
