Product Safety



Is this safe for around the family? 
The short answer is yes, when installed correctly and used as per the instructions on the can, the amounts of active ingredients that are dispensed into the air from the dispenser and circulted via proper ventilation are so miniscule that they will not have any adverse effects on mammals (humans and warm blooded pets). In fact, the amount of product dispensed by an Ecomist dispenser over the course of one day is less than a 5 second burst from a supermarket brand space spray.

The longer, more detailed answer for those that enjoy their detail is as follows:
In order to fully appreciate the safety of using the Ecomist insect Control system, let’s look at each of the key ingredients. Ecomist insect killer has three main components to it; the active ingredients (that do the killing), the propellant and a solvent.
The active ingredients are natural pyrethrins (9g/kg) and piperonyl butoxide (45g/kg). Pyrethrins are the insecticide in the formulation. They have very low mammalian toxicity and break down very quickly once exposed to light so are considered very safe for humans and warm blooded pets. We say warm blooded because pyrethrins are very toxic to fish and other aquatic creatures.
The piperonyl butoxide (PBO) has no insecticidal activity itself, but is a synergist that enhances the effectiveness of the pyrethrins. PBO is a very commonly used synergist and will be found in most formulations that use pyrethrins. Based on toxicology studies, the safety of PBO for human use appears to be extremely high. It’s widespread use and long-term good standing along with the extensive toxicity data generated support this. 

With Ecomist’s insect control system, extremely small amounts are dispersed in the air rather than being directly ingested so extremely unlikely to cause any ill-effects. For a comprehensive review see the section by Rory Breathnach in “Piperonyl Butoxide: The Insecticidal Synergist. Edited by Glynne Jones, 2008”.

The pyrethrins concentrate used in Ecomist is a relatively viscous liquid that requires dilution in order for it to be sprayed out of the aerosol and remain suspended in the air. A solvent appropriate for that function is used.
The propellant in Ecomist Insect Killer is a typical aerosol hydrocarbon propellant (propane and butane), as used in food oil aerosol sprays. 


What precautions should I take while using my Ecomist?
  • Keep aerosol cans out of reach of children.
  • Do not position dispenser directly over food or food preparation areas (as per the NZFSA approval guidelines).  
  • Contents may damage paint, plastic and other applied finishes if dispersed directly onto such surfaces.  
  • Very toxic to aquatic organisms (do not use close to fish tanks).
  • The contents of the aerosols are flammable – do not store them or use them near fires, open flames or other heat sources.
  • We don't recomment keeping a dispenser going in your sleeping areas at night (if the dispenser is set on the low setting it will turn off automatically when it is dark).
  • As with all aerosol products, ensure you have adequate ventilation - this is also important for circulating the product around the areas you want protected or perfumed.  

Has Ecomist been approved? 
Yes, Ecomist has approvals from the NZ Food Safety Authority. For use in food establishments please contact your local franchisee for advise on dispenser placement.

Can I use Ecomist Perfumes around someone who suffers from allergies?
Any perfume can be allergenic to someone who suffers from allergies. If someone is suffering from an acute allergy, especially a chemical one, he/she should stay away from perfume. It is almost impossible to predict which and when a perfume will trigger an allergic reaction; it depends on the sensitivity to the allergy at a particular time. It is a complex mechanism and as a consequence avoidance is advisable.

General Questions


Why use Ecomist rather than a normal fly spray?
Ecomist provides Insect Control Automatically 24 hours a day. Because Ecomist uses only natural pyrethrins it actually repels bugs creating an insect free zone. Pyrethrins are biodegradable as they break down in sunlight so there is no build up of residue. 
What types of insects does Ecomist control?
Ecomist is effective in controlling most insects including flies, ants, cockroaches, spiders, fleas, dust mites and mosquitoes.
Where can I buy Ecomist?
Ecomist is sold throughout New Zealand by our franchise network. To reach your local franchisee call 0800 75 75 78 or you can buy online from this site.  
Will my insect control dispenser also dispense fragrance?
Yes. Ecomist dispensers are designed to take either Insect Killer or any of our range of perfumed cans. 
What are Natural Pyrethrins?
Pyrethrin is derived from the flowers of Chrysanthemum Cinerarifolium and possesses a unique combination of insecticidal properties. It contains not one but at least six distinct related insecticidal ingredients called Pyrethrins.
How do I open my Ecomist dispenser?
You can open your Ecomist by pressing on the bottom of the unit and pulling away the face from the backplate. CLICK HERE for more detailed instructions.  
How long does a can last?
Under ‘normal’ settings (a 30mg dose every 7 mins) a 250ml can would last about 4 weeks.
Where should I place my Ecomist dispenser?
• Install in a location where air currents will circulate the aerosol spray to areas where it is most required. • Mount dispenser about 2 meters above the floor preferably where there is a clear area between the dispenser and the floor.
• Do not install near or next to an open window or extractor fan or aerosol spray will be lost
• Do not install your Ecomist directly over food, or food preparation areas
• Make sure that your Ecomist is installed in a well ventilated area and avoid small enclosed areas with no airflow
Caution: Do not install over appliances or furniture, e.g. Refrigerators, items made of plastic or polished surfaces.
Should I use my dispenser during winter?
At the end of the summer season, flying insects may not be so prolific. However, insects such as ants, fleas, silver fish and cockroaches can be year-round pests. We recommend continued use of your Ecomist dispenser with natural Pyrethrins insect killer throughout the year, although the pest might be kept under control with your dispenser on a lower setting. Just be aware that on the low setting, the E4 turns off at night when nocturnal insects like cockroaches come out. Alternatively buildings can be fragranced using other Ecomist products such as: Ecomist Odour Neutraliser, Ecomist Fragrances, Ecomist Mood Makers

How often do I need to change the batteries?
The batteries will last up to a year in your dispenser. They should be replaced with alkaline batteries only. 
If my Ecomist is not working, what should I do?
Ensure the unit is turned on. The E3, E4 and E6 dispensers have on switches inside the dispenser. The E7 has a power button on the outside of the dispenser Check the can is not empty and the batteries are not flat.
Check the dispenser for signs of leaking – both outside and inside. If there is a leak or dribble this will need to be fixed by an Ecomist technician in order to properly fix the delicate mechanisms inside the dispenser.
If none of the above work, please phone your local Ecomist franchisee for further help. We have a full repair service and all of our dispensers are covered by a 1 year guarantee.

Can I use other brands of refill cans in my Ecomist dispenser? 
Although some cheap copies of our product will fit Ecomist dispensers we strongly recommend NOT using non-Ecomist refill cans in the dispenser. Use of non-Ecomist cans in an Ecomist dispenser automatically voids the warranty and can be dangerous seeing they were not designed to fit our dispensers. Aerosol containers are under extreme pressure and can be dangerous when used incorrectly or in the incorrect system.
