Mortein Fast Knockdown Multi Insect Killer

This works as well as spraying deodorant on a fly - and it was so expensive I had to come and say something but reading others reviews I'm actually in disbelief this is still allowed to be sold!

The most useless fly spray i have ever used, i have sprayed the same fly 7 times over 5 hour period, i will never buy this poor fly spray again total waste of money.Mortein don't you test your products ?

Sorry to say but this product could not kill a flea let alone a fly, but it did manage to kill our kids pet fish in time for Christmas. This product smells and does nothing as stated. Consumer affairs should step in and ban this product for FALSE claims.

This stuff just doesn’t work. The only way you can use it to kill flies is to hit them with the can. I cannot understand how it ever ever made it to market. A joke.

I have had a persistent fly in the house which has been sprayed multiple times with the 'Fast knockdown' and continues to thrive. This is the most useless product I have used and is also expensive.

I bought this product to rid myself of house flies. After several days use, not ONE fly has been “knocked dead”!! In fact, I think they like it!!
NOT HAPPY MORTEIN!!

The only way to kill a fly with this product is to hit them with the can. What happened to Mortein? This was a go-to product and now it's rubbish.

I have never in my life used a product that was less fit for purpose. I direct sprayed flies in my kitchen 5 times and not one dropped. In the end I closed all the doors and emptied an entire can, almost asphyxiating myself and again not one fly dropped. This stuff literally couldn't kill a fly, they can swim in it, you could open a fly resort and fill the pool with this junk and the flies would thrive. What happened???? Mortein used to be the best.

I live in a seaside suburb in Brisbane and this, newer changed formula, insect spray is rubbish, it doesn't work..fast knockdown my a×÷*!
It doesn't even fast drown the flies moths at my place.it just makes the tiled floor and surfaces slippery and requiring cleanup!
I recently found an old (10 years)Mortein fast knockdown spray can in my camper trailer
Which works perfectly with the slightest spray, kills everything instantly with minimal residue!
Come on Mortein, bring back the old formula that works.

Sir, how does one use your fast knockdown? Do we hit the insects with the can or drown them with the spray because your product seems to be very weak. It used to be very good but unfortunately no more.

I sprayed the same fly 3 times and nothing happened. This product is completely useless and I will be returning it to my local supermarket for a full refund. How disappointing.

flies will only die if you drown them in it mortein has been band from our home after 40 years of use in the last 4 years the product has turn into lets call it lolly water. due to disappointment over a long period of time we pledge to never buy this product again!

I thought if I spend more, it would work better than the no name brand, it doesn’t. A couple of times I’ve sprayed cockroaches before I went to bed, the cockroach will run and I will find it in the morning on its back but still kicking. Once I left one till lunch time and it was gaining strength. This stuff does not kill cockroaches, and forget flies or spiders. Worst product ever

I would have been better off spraying water and attempting to drown the fly. The spray had zero effect at all and resorted swatting to kill it. Will not buy again.

Moths, cockroaches, small spiders - no problem, it kills them quickly. But bushflies? Those rotten little pests that hang around all the time? Nope. They’re as indifferent to this as they are to insect repellent.
