Rentokil RKLPS136 Insectrol Insect Killer 250ml Aerosol

Does a good job of killing flies and other bugs quickly. Also seems to stop any other crawlers coming in.

Ended up with a Gnat infestation the likes of which I've never seen before. Literally thousands, enough that it sounded like a wasps nest in the room. I suspect this was due to removing the plant beds outside and leaving the window open overnight so they 'relocated'. It looked like something out of a demonic horror movie. So I tried.. 1. Slowly stepping away and shutting the door. They were still there in the morning, plastered all over the ceiling and the more lively of the bunch swarming above the window line so leaving the window open and asking them to vacate did absolutely nothing. 2. C&G Home and Garden Insect and Spider Spray. Smells nice I guess, is organic, it dazed a few of them before they got back up again and continued the party. The smell is still there a week later, bit sick of it now tbh. Smells a bit like when you visit a house to buy and the owner went OTT with the plugin air fresheners. 3. The buzz fly catcher - outdoor use only. In times of need thought I'd give it a go indoors, screw what the instructions tell me to do, .. did absolutely nothing. As an aside thought maybe it does really need to be outside to work so I placed it, and the spare, in the garden and it continued to do absolutely nothing other than catch 2 or 3 bugs, that weren't even flies.. 4. Whaline Sticky Fly Traps. Comes in yellow squares, and some shaped ones too so the kids can have some fun killing things, can't remember what the shapes are, probably not fly shaped otherwise that'd be a bit much, also come with some sticks to place in the garden for those with better knees than me. Surprisingly(!) actually pretty good. Zero toxicity, Zero smell, but out of thousands of gnats a few of those squares only actually caught perhaps a few dozen in a couple of days and these things were breeding faster than a council estate. 5. Haimist Pesticide free fly paper. Genuinely terrible, so terrible may as well stop reading about this one. Caught zero gnats in the room of terror. Placed a few in the kitchen where house flies were intimidating myself and each other and all they did was fly around it. Notably the flies also ignored the Whaline's too. They're sticky as all hell though, trying to bin them is near impossible, you WILL waste a bin bag attempting to get rid of one, better thrown on a bonfire, better yet... don't buy them. 6. Rentokil Insectrol. Killed them dead, literally within seconds, end of story. I'd started in the corner and backed away until I got out through the door whilst holding my breath, this was my last resort. As I was backing away I could see them falling to the floor, some remainers stayed on the ceiling but they were just as dead. A dyson took care of the rest and now it looks like I'd hoovered up an eccles cake. Slight downside other than probably killing wildlife for thousands of miles is that it coats the walls in noticeably shiny patches, after a few days this went away for most part, I'd have to look hard to find where I'd gone a touch overboard. So yeh that's my experience, wasted £35 trying to be kind to environment and brutal to my wallet, whereas £5 rentokil obliterated my problem before I'd even closed the door. In order of ratings Rentokil Insectrol : 10/10 Whaline Traps: 6/10 Everything else: 0 NB. Probably better reviews to be had.

Works great on German cockroaches! But not much in the can for the price

This stuff was amazing when I had an infestation of some tiny bugs - still don’t know what they were but they’d got into my tea collection and some cereals. I’m usually kind to insects but sorry, you mess with my tea, you deserve this spray. Sprayed all the areas according to instructions and that was it - job done. (Do read the instructions first) Absolutely worth every penny.. extremely effective, easy & fast working.

Did not expect it to be so effective. Sprayed German nymph cockroach’s with it and they died with ten seconds. Amazing!

So this stuff does what it’s supposed to do, but I feel like (as it says in the description), it’s designed to kill much smaller bugs and insects. I used it on a nest of baby spiders in our bathroom and it killed them absolutely instantly, with zero signs of life afterwards. So for smaller insects like ants etc... 5 stars. Larger insects like spiders on the other hand... not so much. I feel the dosage of the poison isn’t high enough and so it causes them to suffer and die slowly. They’re still able to run around unless you completely drench them with the stuff until they’re stuck to the ground unable to move (which I where I suspect many of these “it killed a large spider instantly” reviews come from, unless these people got a different product to me), but unless you completely drown them in the stuff (and sometimes even if you do) they kinda run and stumble around and then start convulsing and it’s all very traumatic. I sprayed one of those spindly ones that hang out in corners the other day with a good dose and it took him minutes to die, all the while he was still attempting to run around and escape. I’ve even had ones that I thought were completely dead that I’ve then sprayed again to make sure and they’ve started wiggling around again (whether it’s just a nervous system reaction or whether they are still alive, it still ain’t nice) so take all these “instant” reviews with a pinch of salt. I understand that this is poison, and no poison really truly works instantly, and this I s how the poison works (It affects their nervous system and causes extreme excitability followed by convulsions and seizures and paralysis and ultimately coma/death), but it’s not nice to see. I’m writing this fresh from the experience of spraying a medium sized spider with a hearty amount of this, only to watch him die a slow and drawn out death. No Bueno. I dislike spiders and try to avoid killing them where possible, but when I do have to kill them (such as them being in a non-catchable location), I’d rather I had a product that killed them quickly rather than watch them slowly die. Stick to smaller bugs with this stuff.

Good

very good stuff
