Spider Killer Spray 300 ml - Fast-Acting Crawling Insect Control, Home & Office (Pack of 1)

I have been using this for over 5 years now as it has been the most effective spray I have found. Effectiveness - Killing Does kill spiders, but usually you need to spray them directly. It's not instant, so spiders might run off, but if you got them square on, they will die. The larger they are, the longer this might take. If suspended on a web, they will eventually drop to the floor. I can't comment on non-UK spiders / really large ones (>4-5cm with leg span) as I have not come across these yet (not sure I want to get that close for those!). Effectiveness - Prevention I regularly spray around window frames and doorways (and within frames / joints / hinges). This does seem to reduce spiders, but the sprayed area is unlikely to kill them if they walk into the area. It also helps keep spiders away from external cameras / lights. Duration The advert says spray lasts up to 8 months. However, rain really drops the length of effectiveness. You will need to re-apply regularly. Guess drier places will find it easier. Smell / Residue There is definitely a strong smell when the spray is used. I try to have windows open for a while where possible to help fumes clear (as advised by the manufacturer). There is an oily residue from the spray, so be careful where you spray. It can be slippery on floors when it settles, so you may need to clean that up. Overall It does a decent job and gives greater peace of mind. Watch out for residue / smell, and reapply as needed (sooner after rain) and hopefully you'll be happier from a spider perspective.

I'm probably more scared of spiders than death which is why I had to buy this. I sleep and do all my work in a small, but cosy, room at the bottom of the garden from my house. The spiders are pretty big down here and are constantly making their way into my room to a point where I'm removing at least 3 big spiders and countless of smaller spiders every night. That's when I thought about buying some sort of repellent to prevent the spiders coming in, and lead me to here. I've read a lot of the reviews on here, good ones and the bad ones, but as the majority of them are good, I considered in buying this. Best choice of my life, this thing works like a charm (And also kills spiders instantly if sprayed at them, so if you don't like killing spiders, try to avoid spraying them directly). I first used this on the outside door frame which immediately drove at least 5 spiders around it to scatter. I've now sprayed the corners of my room, around the window and the inside of the door frame which so far has worked very well. If you are petrified of spiders and can't deal with taking them out constantly every night, then you should definitely buy this product. It's cheap, works very well and keeps you safe. The only downside to this is the smell. It smells a bit like furniture polish, very strong and probably bad for non-ventilated rooms, but other than that it's a great product for removing spiders (Like literally, they run for their lives!). tl;dr Good product, works well but smells bad and not recommended for non-ventilated rooms.

I purchased this product after an invasion of giant house spiders this year. The pest control officer said that there must have been a nest in the house. They were very large and would appear all over the place, including several crawling over my desk! Not very pleasant. I am hoping this product will do the trick. I will use it again from next August to see if I can stop the annual autumn invasion, but it has never been as bad as it was this year. UPDATE ON THIS PRODUCT: It's now October 11 and I started to use the Spider X spray several weeks ago when the giant beasties started coming into the house. Last year was terrible, absolutely HUGE spiders invading every day. Once I had sprayed liberally, I didn't see any spiders for a couple of days, then started to find them...DEAD. This spray might not keep them out completely, but it does kill the ones who come in. Also, there have been far less of them this year. As well as being a deterrent, it must also have some insecticide for spiders in it. This morning on having a good hoover around, we found six more large dead ones. I am going to buy this product again, as I think it's worth the money. I used to hoover up spiders with the SpiderVac, which is £9.99. But I think that once out in the garden, the crafty little critturs just used to come back into the house! Now I am going to spend the money on the spray instead.

It actually works. I wont copy the "recordings" of my experiment but before mean was (95% CI) between 2.7 and 3.2 spiders per week, and they were "good sizes" after ~ 1 spider per month. There's wooden boards outside my window and it's covered in cobwebs so they're still close! So yes, this actually works. I'm writing this because it's very easy to make people think stuff works (placebo effects, so forth) but no, it actually works, I recorded notes of the spiders I've found. I've only found 3 and I've had it for just under 3 months, and these have been much smaller (and also! Never crawled across my bed!) It's great. Previously I used to think "hah, I'll leave that big spider on the stairs, it'll be my sister's problem" and they'd always go the longest distance into my room, and I'd really hate it when they escaped my shoe-swipe and hid under my bed. That doesn't happen any more because I sprayed both the door frame and the windowsil. Some advice: 1) It takes a long time to dry, we have this idiot of a boxer (he's really loving and lovable, but properly thick) and he would lick the door frame anyway, so shut dogs away while it dries if you sprayed it in reach; just for safety. 1.B) While drying, if you did spray a bedroom, try and keep the air moving, again just for safety, if you open a window at one side of the house, and all the doors between it and your room and your window, you will get an air current moving. It takes in the order or 4-8 hours. 2) The particles of the spray are quite slow and heavy, so if you're doing say a window frame you will get some blowback, try and go for still air if you can. 3) I've resprayed the window once every 2 months, it's on the side that rarely gets rained on but does get the sun, I suspect it /could/ evaporate off.

Like many people I have been plagued by HUGE spiders this autumn. They have appeared in my kitchen sink, bathtub, wash basin, living room and bedroom. I've had enough of them, they knock me sick. Having noticed that they come into my living room and then the rest of the house via gaps in between the fridge and cooker etc. in my kitchen, I sprayed in those areas. Now then, the smell of this stuff is pretty awful and for a few days my kitchen smelt like a public lavatory frequented by petrol-drinking gentlemen with a penchant for pis*ing on the floor, up the wall, and anywhere else other than where it is meant to go. I nearly binned the stuff. However, it seems to have done the trick. Not only has it deterred the spiders, I noticed that it may have killed one stone dead on it's journey to my living room overnight. However, I haven't redone the sprayed area for just under two weeks and I have noticed another huge spider tonight. I'd suppose I'd best respray the area until I can find a less pungent alternative. My recommendation is to perhaps give it a go. Yes, it's expensive and it's a pity it initially smells like a combination of petrol and pi*s, but rather that than sharing my home with a thousand eight-legged agents of doom. Of course there are alternatives that I haven't tried so you may be better off elsewhere. I will soon be following suit. I do think that the product description regarding the spray being odourless is an OUTRIGHT LIE so my rating is reduced accordingly. I will be contacting Amazon about this product misrepresentation so it is changed. Update: After having sprayed this stuff in my kitchen for a second time yesterday evening I decided its foul smell was too much. I phoned Amazon and complained about the misrepresentation of the product in Amazon's description (which they are now investigating) and they gave me a full refund. The spray is now where it belongs, in the bin!

The fun of arachnophobia... Non-sufferers laugh at us but for those of us gripped by the irrational fear of The Eight Legs, it's not funny. I never fully got over the incident, over twenty years ago, when I slid my legs into a freshly laundered pair of jeans only to see something with too many, fat, hairy legs crawling up my thigh. Since then everything that's come in off the washing line has been turned inside out, hit with a stick and exorcised before being worn. If you're scared of these things, they're terrifying and being alone in the house and seeing one go scuttling along a wall is in the top five worst nightmares. Where I live is on the edge of a small rural town, and my garden backs onto woodland, really dense, dark woodland which is the home to a multitude of Eight Legs. Like Mirkwood without the elves. From early September, I stop opening windows. I'd have the entire house hermetically sealed if it weren't for the niggly bit about having to go out sometimes. Being a country girl, I like my fresh air, and the lack of it in the house on a crisp Autumnal morning bothers me. I often gaze wistfully at the windows, wondering if I dare open them, but the fear of being invaded by monsters from the woodland, beasts with bodies like maltesers and legs like pipe-cleaners, makes me realise that living in a stale, stuffy house isn't so bad really. My mum suggested that I try this. I was sceptical at first but gave it a try. I sprayed it around just one window at first, to try it, and left it open about an inch. Being slightly obsessive in my fear of the Eight Legs, I sat and observed the open window, with the blind rolled up. Nothing walked in. I felt a little braver after a while and left the window unobserved, starting to feel that I trusted the spray. I closed my window later that day, and saw nothing crawling or scuttling in the house. The next day, and the next, I had the window open. Still no Eight Legs in the house. Not a one. This from someone who is genuinely terrified of open windows in Autumn. I feel truly confident that nothing will walk in through the window with the sprayed edge, it's as though Gandalf has given me a magic spray to protect me from the Monsters of Mirkwood. It's worked wonders for me, it's wonderful to have fresh air in the house without the constant fear that used to accompany it.

I bought this spray for a massive, eight-legged landlord who’d taken up residence in my bathroom on Monday. By Tuesday, the package arrived—faster than the spider’s eviction notice, honestly. I sprayed the bathroom like I was fumigating a crime scene, shut the door, and waited. A few hours later, a tiny baby spider crawled out, looked around like it just saw the light bill, and promptly expired. Tragic, but also… not my kid. Then Wednesday rolls around, and guess who stumbles out? Big Mama Spider herself. She wasn’t doing her usual Usain Bolt impression anymore—more of a wobbly pub crawl. So I grabbed the spray and gave her a taste. Suddenly, she charged at me. Not aggressively, more like a drunk uncle at a wedding—lost, confused, and inexplicably drawn to the mist like it was a fog machine at a bad club. She staggered, stopped, and gave up the ghost. And then—because I’m a cautious soul—I stamped on her. Just to be sure. You know. For peace of mind. When I read that back, it sounds like I’ve written the opening to a low-budget horror film. I don’t know what’s in that spray, but it turns spiders into tragic Shakespearean characters and me into a war criminal with a slipper.

Bought a can of Spiderex after an influx of sizeable false window spiders (had it confirmed by national history museum) decided to make their homes all over our patio doors and windows. It certainly does the trick, when sprayed on an offending spider, it seems to make them shrivel up and sort of 'dry out'. I tend not to hang around after spraying them, as initially it does make them go quite frantic, which is not for the fainthearted. I would usually would not condone this type of method due to cruelty reasons, but due to the numbers of these false widow spiders and size of them, sadly we have had no other option. The spray is also excellent when used as a preventative measure, spray it around door frames, window frames and the spiders wont make homes there. The only negative is that it is certainly not 'odorless' as described, it has quite a pungent & potent poison type smell, if using inside best to air out area where you've sprayed it, which is why I have rated it only 4 stars as opposed to 5, but otherwise, it does what it says on the tin and is an effective way of preventing spiders.
