RentokilRKLPS136 Insectrol Insect Killer 250ml Aerosol

Works instantly on any bugs, spiders I've sprayed it on. I did not try it on bed bugs as we don't have bed bug problems, so can't vouch for its usefulness in bed bug situations.. any bug/spider I sprayed this onto would start acting odd almost immediately - erratic uncontrolled actions, spasms, before dying shortly after.Active ingredients are permethrin and d-allethrin - 2 effective types of mosquito repellent that has been used for over 20 years worldwide on clothing and mosquito nets to prevent the spread of deadly mosquito-borne diseases such as dengue fever. These chemicals, when used according to the manufacturer's recommended guidelines, have a good safety record and low toxicity on humans and poor absorption through the human skin... though please keep it away from young children as ingestion could require a trip to the A&E. The active chemicals could irritate people with allergies according to the info I found online, but as a lifelong allergy sufferer myself, I did not find using this spray aggravated my symptoms in any noticeable way.I have found that spraying it as a preventative measure in nooks and crannies where insects are known to appear seem to reduce the number of said insects noticeably, though not completely. That said, I do appreciate the fact it has gotten rid of many insects for me. I can contend with the odd one that appears. It is the most effective insecticide I've used so far. The smell can be quite pungent... make sure you ventilate your rooms after spraying.

Used the product to get rid of a infestation of Slater insects, works great

This worked great during the summer in my single garage. It got rid of a lot of small bugs hiding in gaps, killed a few beetles, and even repelled other insects like spiders. The only downside is that one single garage uses up the whole can. Definitely handy, but keep that in mind!

This one Dey work o….it killed the cockroaches very fast

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 ratingsRentokil Insectrol : 10/10Whaline Traps: 6/10Everything else: 0NB. Probably better reviews to be had.
