Application Tips

Q: Can I spray repellents on buildings?

A: No. Do not spray liquid repellents directly on building surfaces, due to potential staining. To protect building structures, create a perimeter treatment using a granular repellent.

Q: Is it okay to spray repellents on all flowers?

A: Yes. Always test the product in a small area and wait 24 hours before full application, as some flowers may be more sensitive. Some sensitive varieties may be restricted, but generally, Havahart® repellents can be used on flowers. Always use as directed.

Q: Do I have to rotate repellents so that animals don't get used to the smell?

A: There are no studies currently available that show whether rotating animal repellents will increase their effectiveness in deterring animals.

Q: If I spray repellents in my yard, will animals go into my neighbors' yards?

A: Yes, it's quite possible that the animals will move into your neighbors' yards, where they do not detect the scent of a repellent.

Q: How often do I need to reapply Havahart® repellents?

A: Every repellent is different, but all Havahart® repellents last up to 30 days or more.

Q: What kind of repellent can I use to protect my vegetables?

Repellent Types

Q: What is the difference between a ready-to-use and a granular repellent?

A: A ready-to-use repellent is a liquid repellent, best used for multi-surface protection. Apply liquid repellents directly onto trash, soil, plants and other areas on your property where there are signs of animal activity. Granules are similar to pellets and should be sprinkled in and around areas you want to protect. By sprinkling the granules along garden pathways or around flowerbeds, you can create an effective perimeter to deter pests from entering these areas. Use both liquid and granular repellents for the most thorough nuisance animal protection.

Q: What are the benefits of an electronic repellent versus a non-electronic?

A: There are several benefits that electronic repellents offer that can make them more convenient and economical than other repellents. For example, since you never have to reapply, they're low-maintenance, and you only need to purchase them once. Also, electronic repellents like Spray Away® can be used to repel a much wider variety of animals, which makes them more versatile than other repellents.

Q: Do I need to reapply animal repellents after it rains?

A: Yes, reapply if there is a heavy downpour, or if it rains within 24 hours of spraying.

Liquid Repellents – Liquid Repellents should not be used in wet or damp conditions. If precipitation occurs, wait for dry conditions to ensure optimal protection.

Granular Repellents - More frequent reapplication may be necessary after heavy rainfall.

Q: What repellents can I use in cold climates?

A: The best repellents to use in the winter are granular repellents, Deer Off® Repelling Stations, or the Havahart® Electronic Deer Repellent.

Q: I live in a rainy climate, will repellents work for me?

A: Havahart® repellents are long lasting - even in wet weather. If you experience heavy, frequent downpours, you may need to apply more often.

Q: Will liquid repellents work in cold temperatures?

A: Yes - the product must be sprayed before temperatures drop below 40 degrees. If sprayed after temperatures sink to 40 degrees or lower, a liquid repellent can freeze and cause damage to the plant.

Sprayer/Spraying Tips

Q: What is the best type of sprayer to use for the concentrated forms?

A: The best configuration would be a 50-mesh in-line screen and a diaphragm pump. The higher the pressure, the more likely it is to blind the screen, so an ideal pressure is about 150-250 psi.

Q: How can I fix a clogged sprayer?

A: Rinse the sprayer with warm clear water, until 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 - mix back into solution before the sprayer is activated. With only diluted, flowing material entering the sprayer, you can significantly reduce clogging in the tube and sprayer head.

Be sure to rinse the sprayer after each use.

Q: How long after spraying do repellents need to dry in order to become effective?

A: Repellents starts to work immediately after spraying. If it rains within 24 hours of application, the repellent should be reapplied.
