Okay if not Great! We've only tried this to check the scent & not actually used it on bugs, though we have no doubt that it would be as effective as any other insect sprays. I'm sure used outdoors or in say a garden or shed it would be great. What we found was that the scent is much like kerosene, not unpleasant but it lingered even the next day when only a short spray was used. It was reminiscent of the first Moreton spray all those decedes back (ah, the nostalgia). A lemon scent would have been prefered. The shelf price is excellent so I'm confident it should be a popular product!

Awesome knockout. Yeah! It was an awesome knockout. Usually we have some ants in the bathroom over summer. Probably due to the hot weather they come into the house through the sink outlet. My daughter is allergic to strong smell and chemicals. I sprayed just a little in the bathroom and it was an instant knockout. No smell. Hurray. The ants never return since then. What an awesome product. Will defintely buy this product for such a good price. Best of all, no SMELL!!!

Fly Killer. This is $2. 50 compared to the one I have been using which is six dollars something thatâs a saving of $4. 00 dollars a can. I normally donât buy cheap fly spray as they donât kill the insects or you have to practically use half the can but not this one killed the flys dead with two shots of spray. It is fragrance free but it does have a little smell I normally buy odourless as I hate the smell of fly spray it makes me cough and I feel like Iâm choking but not this one. Can said it kills eight different insects which is good one can for many pest. As the saying goes when youâre on a good thing stick to it I wonât be buying the brand names from now on.

Not really a â Force be with you. â. It took me quite a few sprays of this fly and insect killer to send a blow fly that had followed me through the front door to even knock it to the ground and a couple more to get it to roll over and die. At $2. 50 the price was right but unfortunately it did not live up to my standards so I would not purchase this product again.
Works well. It's not every day that I walk around the house hoping to see a fly, but new things always happen in the Bunch club. Thankfully I managed to find some outside under the patio and they got to test out the spray. The first thing I noticed was how fine the spray was, which helped it stay in the air longer and more chance of a hit. The aroma wasn't offensive and most importantly it killed the flies quickly. This product works and is significantly cheaper than the brand names. Some of the brand names promote "natural products" that I have never heard of & if I was eating this, it may come into play, but to kill flies, this just needs to get the job done efficiently. Would buy this again
Great price. When compared to the more well known brands, the price of this product is very economical. For this reason alone, I would buy it again. I tried it on a cockroach who managed to sneak through the back door and it knocked him on his back and put his legs in the air quite quickly. The smell didn't seem as pronounced as other sprays I have used in the past and that is a good thing. I did, however, have to wipe up some residue spray off the floor but that is probably because I sprayed the vermin a bit vigorously. I certainly would buy it and use it again.
Ultimate Assassination Weapon. So it has taken me a while to use this product, it's almost as if the usual flies that loiter around any opening knew this product had entered my home and made a decision to stay outside for their safety. Then it happened my worst fear those flies had taken revenge and sent in the roach!!!I grabbed the First Force and while trying to concentrate on spraying the intruder, my subconscious knew that at the same time I had to evaluate all aspects of my weapon of choice, the insect killer. From a distance I sprayed not once but twice, just in case. It ran in one direction, me in the other, and then it just flipped on it's back and suddenly stopped moving. I thought it was playing dead, I have seen documentaries on these nasty creatures and ... MoreUltimate Assassination Weapon.

I thought it was playing dead, I have seen documentaries on these nasty creatures and know they are actually quite smart. I walked away waiting for another family member to check and dispose of the nasty thing and yep sure enough it was dead. I must say I was impressed, practically odourless with a good spray of thick mist that did not leave a residue on my floor, definitely fast knockdown, I shall never cower in fear again!Excellent Product, good size can, I will purchase again.
Not impressed. I used this can of fly spray the other night when I seen a dirty cockroach in my lounge room I had to use it more then several times to kill the thing- it did knock it down from the wall but not necessarily kill it straight away I ended up flushing it down the toilet which infact was still alive, I've used Atlas-(Aldi brand) in the past & it does a much better job then this one but that one has a fragrance to it which isn't good if you have breathing trouble but have learnt to bear with it I was looking to try something different that would do what it suppose to without the fragrance so far not too impressed with this product, it's nicely packaged & priced at $2. 50 for a 300g can-this is cheap, the spray nozzle works fine, it says you can use it on:- ... MoreNot impressed.

Effective and efficient. What a fantastic find - a truly fast knock down spray for multiple insects ... I was very impressed. A light mist when applied, easy to press nozzle and a nice large can, this is an effective spray to kill various insects. Flies were particularly easy to knockdown with this product. However, whilst I donât mind the scent (itâs not overpowering but still distinctively smelt like âfly sprayâ) I donât think it should be labelled as âfragrance freeâ. Either way, Iâm sold! I will definitely be buying this cost effective insect killer again.
Quick and Effective. I tried this on a few different creepy crawly and flying insects and found it works quickly. The spray comes out in a fine mist which helps to make the product more effective. The spray says fragrance free which it is but it does have a slight smell but I did not find this irritating. My son whom hates fly sprays walked into the room just after having sprayed the product and wasnât even aware that it had been used. Normally one to complain it affects my nose donât spray that stuff. Sold at a great price and effective my new brand and worth a try if you havenât.
