Raid Rapid Action Fly & Wasp Killer, Fly Killer Spray For Indoor Use, Pack of 6 (6 x 300ml)

Raid is an excellent insect killer. Very effective and good value for money.

I have used this spray previously, and it is very effective against flies. Wasps seem to be a little more resistant to it, but do succumb to it's charms after 20-30 seconds. It seems the bigger the insect, the more resistant they are, as I had to spray a large hornet multiple times before it dropped dead on the floor. But to kill flies and bluebottles, this spray is brilliant. Use it sparingly though, because despite the pleasant smell, you don't want to be breathing this in, as it will cause breathlessness, and god knows what else if it gets in your lungs. If you can, just use short bursts directly at the insects. Only if you have a major problem should you spray into the air to treat the entire room, then you should leave the room for an hour or so, and ventilate the room when you return. It has a long lasting effect when it settles on surfaces too, and acts as a repellant for crawling insects, such as beetles, woodlice, and spiders, so you can spray it on painted or plastic surfaces, but wood may be adversely affected, so I wouldn't risk it. It should be fine on carpets though, just remove pets from the room beforehand.

Does exactly what it says on the can. I work in a primary school and had lots of the little things buzzing round, annoying everyone. Unfortunately the headteacher wouldn't let me spray them as their parents would apparently have complained, so had to only use it on flies. Good value. Very effective, killed the majority of the flies and biddies throughout the summer. Good quantity for the price too. Only downside was delivered by Evri, who after telling me "nobody on site" - 11am on a schoolday so over 300 people on site then reattempted delivery at the local public library (next door) by leaving it on their doorstep the following day at 3pm. A confused librarian brought it to us.

So every year I go through the same annoyance of loads of flies landing and cr*ping all over the worktops, lights and door frames! I've got the fly tape. I tell the children to close the front/back door. I've even got an aversion to the Dettol spray scent through using so much (cleaning after them and AT them to drown the f*s!). But finally, a spray that works ;) it's pleasant smelling which is the first bonus as was expecting it to smell rancid for a fly killing aid nor does it catch the back of your throat ;) I purchased in bulk so always have a can to hand. To be honest there's not too many around YET and I do try and shoo them outdoors before they meet their doom but their drive is real! Anyway, it does what its meant to...bye bye buzzy b*st*rds...now for the negatives... It's not instant working so if traumatised by the sound of their last buzzing moments (no worse than the tape but at least with spray they're not starved to death while lay stuck to a gloopy grave!) maybe get a more humane alternative (or stick with tape so don't have to hear them) although it's only about 10-15 seconds of a decent spray ;) the downside to it taking a while is that you don't know where they're going to end up as they can get far enough while takes effects then disappear...so either watch until they drop then dispose or be prepared to find their bods hiding behind a vase or squashed on carpet later. I look forward to a summer of fewer flies in the home and fewer poo spots around the fixings. Not sure I'd use for treating a whole room due to the airing needing after but a short spray on a group seems effective enough...unless you have a huge problem (my sympathies!!).

I come from a bygone era where a squirt of fly killer caused the critter to drop of the sky but .. perhaps sadly, regulations prohibit that. This comes close ... I had a different popular brand which the flies laughed at. One squirt of this stuff and you can see the flies clearly bothered and then they die shortly afterwards. Not too bad a smell - I just cover anything that may be in contact with food and deliver a small blast of this stuff. Value wise it works out cheaper per can than the other brands if you buy in 6's

Always reliable. Cheaper alternatives easily cost more, at a ratio of 3 poor {Sanmex} to 1 Raid.

These are very effective and easy to use. Strong smell so make sure you're not in the room or have ventilation afterwards. They work fast and last ages as you don't need a long spray. Killed flies, blue bottles and wasps but dont seem to kill fruit flies. Tries on spiders but it didnt do anything. Good to have handy for the summer.

Supposed to be rapid knock down for flys and wasps. I've sprayed a fly 5 to 6 times with this sprayed and its still flying around. Im wondering if I got a bad batch of 6 cans here?

Perfetto. Grazie.
