## Description

Product Description

Review: Worked like a charm *UPDATE 07/09/2023* - I hate spiders, Hate Them!!! Needed something that would not just kill spiders but stay clear. Sprayed all in the nooks and crannies of the garage and the blighters tried to run. Only took a few seconds to kill the small ones. Larger ones with the span of a playing card take about 5 minutes to fully die. One problem I had was the lid would not come off. No matter how much grip I used. In the end I had to use an adjustable wrench with a cloth. Used minimal grip so it didn’t crush the lid. Seems to be the opening foil cover that’s the issue. Once it’s off it’s not an issue. ***Update: Bought a second batch as the heat is on and they are starting to appear. Sprayed around the house doors and windows and for the past week not a single spider. The worst area was the balcony. THEY ALL GONE!! Uploaded a vid of how fast you can expect it to work when sprayed directly on them. Note that I sprayed it 10 seconds before I started recording.
Review: Great - Does what it needs to keeps that out for good 2 weeks. Is very very strong. You dont wanna breath in the same room for about 4 to 6 hours minimum. Great value for money as it does get rid of creepy crawlers. Does not however kills rats (yes i tried).

### ⭐⭐⭐⭐⭐ Very effective 10/10
*by L***L on 17 August 2025*

Update to add even 4 months on the spiders aren’t back yet! Still see new dead ones where I sprayed this on occasion tho. 73 huge false widows (and way more babies) I had in my garden and never knew as they only came out at night 🤮 all over the kids play kitchen and climbing frame too so they had to go! This stuff was AMAZING, put it in my own pump action spray tank and killed every one of them in a couple of minutes 🫶🏼 Haven’t had any back since either as I used it to spray around every window and door and all down the fence panels and side of shed!
