Animal Repelling FAQs
Answers to Animal Repelling FAQs
Q: If I have a clogged sprayer, what should I use/do?
A: Rinse the sprayer with clear water, until all dry pieces of repellent are gone. To prevent future clogs, always shake repellents vigorously before spraying. Shaking the product ensures that the active repellent ingredients, which have settled to the bottom, go back into flowing solution before the sprayer is activated. With only flowable material going into the sprayer, you can significantly reduce clogging in the dip tube and sprayer head.
Be sure to rinse the sprayer after each use.
Q: Will liquid repellents work in cold temperatures?
A: Yes - If the product is sprayed before temperatures drop below 40 degrees.
A liquid repellent can freeze and can cause damage to the plant, if sprayed on a plant at temperatures below 40 degrees.
