If you are ok reapplying repellent about every 6+ weeks then use BANGBANG. It also offers an NPK feed which will boost tree health and resilience as well as offer protection.

If you want 6+ months protection then use our FAT-based repellents either FATBANG or GREASEBANG:


  1. Use GREASEBANG if you have about 500 or less seedlings and can hand-apply the grease onto each seedling.  

  2. Use FATBANG if you have a backpack sprayer and more than about 1000 seedlings and want a faster application. A 4L pack will cover about 1000 seedlings with a light spray when packed in bulk prior to planting.


    1. Use GREASEBANG if you have about 500 or less seedlings and are ok about hand-applying the grease onto each seedling.  Protection will last 9-12 months depending on conditions.

    2. For larger trees OR 1000+ seedlings then use FATBANG. Only a light coat is needed per seedling, at growth points only...LESS IS MORE! 


BANGBANG is more targeted at lifestyle-blockers and home gardeners. As an animal protein based product it naturally oxidizes and degrades over time in air and sunlight and so needs to be reapplied 2-3 monthly for maximum protection. Its inherent NPK also nurtures the tree so is more attractive to the smaller land-owner who lives on site and who can more easily keep a close watch and do a monthly application. It is a potent protein based animal repellent with a minimum 6+ week protection profile. 

FATBANG is based on animal fat and aimed more at forestry, shelter-belts, lifestylers and property owners who require longer term protection for trees and seedlings where the visual impact of a light fat coat on the plant would not be an issue, or monthly visits are not possible. A 6+ month protection profile is possible with FATBANG.

GREASEBANG is mostly animal fat and must be applied by hand, so it is more labour intensive and suitable for smaller volume applications. If the pre-planted seedlings are in bulk in a box then it is easier to apply by just smearing the tops of the seedlings. The grease will offer protection for over 6-9 months.  Use GREASEBANG if ring-barking is evident.

ALL formulations serve as potent animal repellents that help prevent deer, rabbit & hare damage as well as repel possums and wallabies.

NO...we manufacture, package and freight our own products from Nelson. The repellents are made in small batches then shipped out to order - this means we offer them at a better price...this is direct-selling straight from the manufacturer.

You can buy through this website either via direct bank transfer (preferred!) OR credit card. 


There is no real expiry date for the repellents. For FATBANG and BANGBANG if the containers are going to sit around for an extended period then once every 90 days or so give them a good shake to keep them mixed. Keep the out of sunlight in a cooler spot. Most emulsions will separate over time if left long enough, so a good remix will keep them in an ideal state. The repellents should have a viscosity that is similar to cream.

For GREASEBANG there is no expiry as long as it is stored in a cool location. Prior to using sit it in the sun to help soften the grease if too stiff, or microwave at LOW POWER for 3-4 minutes.

Keep all containers well sealed, do not mix with anything else.


NO...there is no pest repellent that is 100% guaranteed effective! The only real 100% method would be a secure fence. If the animal is stressed, starving, or just curious then it might take a look, but a PESTBANGED plant will be a last resort food source, and the animal will usually dine elsewhere. Note that these animal repellents do not kill or maim or poison the animal, they repel only.

As for other pests - we have tested FATBANG and GREASEBANG on horses to good effect to stop them eating young native seedlings, and to stop them ring-barking shelter trees. They seem sufficiently repulsed so try that if you have horse damage, especially wooden posts, stalls and structures. 

Goats or Stock?...expect mixed results. FATBANG or GREASEBANG would be the better alternative for these pests.

If you are just targetting ring barking damage then the best rabbit repellent is GREASEBANG.


NO... these are pest repellents only. They are repulsive to a wide range of herbivore browsers that damage plants, seedlings and trees. Unlike leg-hold traps and agrichemical poisons they do not maim or cause suffering. Our odour-based repellents use 100% natural active ingredients that encourage browsers to dine elsewhere. 


NO... consumers now demand safer and natural products and this is our basic mission! Our repellents are based on 100% natural active ingredients that are sourced from our primary industries as byproducts, and therefore need no further processing to extract them. 

Agri-chemical sprays like calcium chloride are toxic to both the user and environment, plus they are useless anyway as they rely on the pest eating your tree to get a taste of it, by then it's too late! SEE OUR BLOG ON THIS SUBJECT! Although our repellents are safe to use best-practice advice is to wear a mask to avoid breathing in the mix if spraying. Wash hands thoroughly after use.


Our animal-protein repellent BANGBANG offers 6+ weeks protection depending on environmental conditions DO NOT REAPPLY sooner than 6-weekly!

Our animal-fat repellents FATBANG and GREASEBANG offer 6+ months protection. DO NOT REAPPLY sooner than 6-monthly!

Animal-protein based repellents like BANGBANG work by slowly oxidising and releasing a sulphurous odour that repels through smell as it decays. They do work, but over time will breakdown in air and sunlight which limits their effectiveness. This applies for any animal protein based repellent. That's just the way nature works...protein will naturally decay and rot away. So a 6-9 week effective protection period is about the most you should expect and it will need to be reapplied, especially for new growth. DO NOT BELIEVE the hype from some other animal-protein based repellents (including imported powdered blood by PLANTSKYDD) that claim longer term protection.   

Fat-based repellents - and there are none made here in NZ except FATBANG and GREASEBANG - offer a much longer protection period as the coating of fat serves as a natural sticker-spreader. When plants are dormant the fat layer can remain for around 6 months, GREASEBANG a bit longer. Even if the smell has dissipated the fat coating will still offer protection. The coat may have a light white tinge on some leaf margins where the fluid may have congealed when drying. 

For these repellents the dormant season will offer more protection as there will be little growth to dilute the coating. For spring/summer a more frequent light spray may be required on new shoots. Because of the huge variety of plants/trees and local conditions we suggest a small trial spray to test for any adverse reaction. DO NOT DROWN THE PLANT...ALWAYS SPRAY VERY LIGHTLY...JUST A WHIFF COAT! ... LESS IS MORE! 


GREASEBANG is the best repellent to prevent ringbarking. Apply a thick band of the grease by hand onto the tree stem or trunk. It will easily stay on the tree for 6+ months. It is repulsive to browsing herbivore pests. While you're at it smear some grease onto growth points and the top of the tree where there is potential for attack.
