## Description

Effectively eliminates crawling insects with fast-acting, low-odor spider spray suitable for indoor and outdoor use on surfaces like door frames, windows, and cracks.

Review: Works Well - 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.
Review: It really does work! - 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.

## Questions & Answers

**Q: Price query - £11.53 for one, but £34.33 for 2????**
A: I think the higher price is based on the weight. Why not place 2 orders (one after another) and have 2 bottles for £23 :)

**Q: can you spray this on side mirrors of your car as i have constant spiders webs stemming from side mirrors**
A: It'll do no harm, although I haven't tried that myself. It has been very effective in reducing spider numbers around outside lights, porches and gutter areas. Doesn't kill the spider immediately..but they appear to carry the spiderex back to the nests..and they die in clusters there. Been a good product in my experience

**Q: I have a problem with spiders webbing from the curtains to the windows. Does this spray damage fabric?**
A: I have sprayed this near to my curtains and around the bottom of the divan bed,(which is cloth). I must say that I havn't noticed any damage to either. I also spray down near to the carpet, as yet no problem. Hope this helps.

**Q: Does it kill spiders if sprayed on them or near them and how quick**
A: Yes it certainly does, if you spray them directly, depending on size of spider it will kill it within a minute, you only need a short burst of spray, and if you spray an area and they walk on it they will die too, I've found it lasts a number of weeks before you re spray the area. I honestly can't recommend this enough, it is a great product.

### ⭐⭐⭐⭐⭐ Makes those spiders run for their lives.
*by A***Y on 22 July 2014*

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.
