After some weeks use I began to suspect Naturgard was relatively ineffective so I sprayed a room then trapped 3 of the flies in a jar, easy to do as they were obviously made very ill by the Naturgard, unable even to walk normally, but 12 hrs later all were fully recovered and flying robustly inside the jar.
We had bought a whole carton trusting in a brand name, now very disappointed in and wary of Mortein products.

It doesn't have that strong scent that chokes you with one spray.

It does its job . The mozzies were out on full force this weekend so I had to go get spray and I'm glad I found this one .Sprayed twice and they were gone.

Coles had them on special 6 bucks each so it's a bargain considering the others cost more wherever you go.

I like to keep the doors open in summer and flies are an unwelcome outcome. I was hoping that a short spray would clear the room. Unlike other reviewers, I have experienced some positive outcomes but I wouldnt buy this product again. It's been years since I've used a spray and I dont think that I feel comfortable with spraying a lot of chemicals into the air. Maybe the safety requirements on aerosols like this, result in a product that simply doesn't do the job. I will be looking at more electronic solutions in the future.

Have tried many times on 0800 number to complain, continually getting disconnected, have left voice messages, no replies. This product 100 % will not kill flies. It is now time to open up social media and to become a "fly in the ointment" with the major supermarkets here in NZ that Reckitt Benckiser, as a company "YOU SUCK"

This product is the biggest waste of money! Doesn’t kill flies unless you use enough to almost kill yourself! Disgusting I will make sure I tell everyone I know not to waste there money!

It takes a lot of spray to kill a single bug. Might as well drench the bug in water with a spray... The bugs react the same way as it would if you sprayed it with water.

I will never being using this product again. I had a severe asthma attack and my husband could not stop coughing and we only sprayed it for 10 seconds. Take it off the market before it kills somebody. How can you pass that as environmentally friendly and rain forest approved. How did it pass its tests in the first place.

First review I have written about a product, do not waste your money, does not work. Not sure what 'national park edition' on can signifies??? I thought 'mortein' was a brand I could trust.

I have used this spray only twice and both times have had hay fever symptoms to the point where it feels like I have the flu almost instantly. Both myself and my partner have this problem and we don't have any allergies that we are aware of and do not suffer from hay fever. I would not suggest purchasing this product unless you want to spend the night sniffling. It works well at killing the bugs but I will not be using this product indoors ever again.

As a single mother I must wear the pants and remove all the creepy crawlers and what not from my home and especially the children's bedroom. I put my faith in a bottle of Insect killer so I didn't have to do the grossly unthinkable and smush it with my bare hands. And I was completely destroyed when I realised that's expensive bottle of fly spray DOESNT KILL ANYTHING!

Seriously why is this even on the shelves? Did you guys test it before deciding it will kill insects and selling it to the public?

Never again.

I bought this product because previous Mortein products worked. Like all the other reviews this product is 100% useless. Very disappointed since trying to enjoy a Christmas lunch out doors. The flys appeared to enjoy the bath when in contact with the spray and happily flew away. The Mosquitos just kept flying around until slapped with hands. Hopefully the manufacturers will read the feedback and fix this problem. It might as well be a can of water.

My cousin convinced me to buy it as he thought it is safer to use natural products. Well, I ended up emptying half canister for a few cockroaches. I found my self spraying four or five times for each of them. This product is an uttermost crap!

My husband bought two cans of this on a malti buy special...Well now i am stuck with two cans of bad insect 'killer'....It doesn't work at all, i have used it on a white tail and another spider and literally had to drown it before it even thought about dying!! I will stick to using a killer that has no natural products!! They don't work!!!

I rarely use fly spray but occasionally I need to and so purchased this product. I spray it directly on the flies and they just fly off as if nothing has happened and continue flying around the room. It's like using nothing at all. I don't know if it kills mosquitos but I won't be purchasing it again.

It didn't kill flies

Purchased thinking this would be good as it is a Mortein product and it just didn't work. I used it aiming straight at several flies and they just kept buzzing around happily. It seemed to take anything up to an hour to work on them when it actually worked. Whatever Mortein is made up of now, bring back the original version.
Nothing
Didn't work effectively
