Zero In Wasp Nest Control Powder 300g – Kills Wasps at the Nest, Indoor & Outdoor Use, Accurate Puffer Applicator

I don’t normally write reviews, but this stuff is damn magic, I had a nest in a flat top roofed utility extension, huge nest that you could actually hear humming away in the evening. I inverted the pack, shook it with a finger over the spout to prime it, puffed in two sprays, just two. Lots of activity straight away. Then later it went quiet. Day later not a single wasp, none. I 100% recommend this product, it works a treat, it’s easy to use, just be sensible, spray late evening when the nest is going quiet, have an escape route ready, spray and get out the way, go back for a second puff if needed and get away. Leave them to it. Job done

TLDR - two evening applications and all wasps are now gone! I had a wasps nest in between wooden sleepers in my garden. I couldn’t see the nest or the specific entrance so had to guess a bit when doing the powder. There were about 4-5 wasps at a time near the nest during the day to start with. For the first evening application I did two puffs of the powder. The next day there were 1-3 wasps on average at a time. That evening I did about 6 puffs and aimed more inside the crevices. The next morning there were a couple of wasps but by the afternoon there were none. It’s now almost a week later and there’s still no wasps there. I was worried the powder would disturb/wake up the wasps at night when I was doing it but luckily it didn’t. I still have about a third of the bottle left.

Saved my day! Worked first time. Had nest bedded in outside wall and only able to use powder. Gentle but very effective. Sprays and foam only entice the wasps to attack .

Sprayed over the nest late evening time. 12hrs later no sign of any wasps. Great results, quick and easy

Really, this powder is only effective if you have a clear sight of the wasp nest, so you can apply it directly to the nest. A further limitation is that it really requires you to be able to apply the powder from above the nest, because then gravity will aid you; otherwise, gravity is your enemy. Except in the most straightforward cases, therefore, this powder might only be effective if you also buy a "Wasp Nest Killer Bulb Duster Applicator" (a sprayer) to apply it. For example, the Bettsolt Sprayer at £11: https://www.amazon.co.uk/Bettsolt-Applicator-Control-Sprayer-Diatomaceous/dp/B0GLP567KK/ref=sr_1_7 But in practice, you are probably more likely to need the more expensive Sunyay extendable powder sprayer, which has a special dust holder (that looks to be more effective), and which has an extended reach of nearly 4 foot, at £18: https://www.amazon.co.uk/SUNYAY-Sprayer-Diatomaceous-Multi-Purpose-Adjustable/dp/B0CBNW5SNK/522-3199817-2551761

First use tonight, wasp nest entrance in garden wall dusted, soon covered in big pile of wasps, all very busy trying to get back in. Had to prod entrance with a long stick as dust had actually blocked it, which meant they could walk it into nest. Could see wasps getting covered as they went in and out, and then dropping off to die. 30 mins later, activity minimal. Looks very hopeful

Brilliant stuff !! I tried the spray foam a couple of times, but because the actual nest was under some garden steps with access via a hole in the ground next to them, I dont think the spray got as far as the nest. I am allergic to wasp stings so they had to go. It made sense to use the powder as I could line the tunnel with the dust and let the wasps take it into the nest. I bought an extended puffer (also available on amazon) and gave the inside of the entrance tunnel a good coating of the powder and beat a hasty retreat. Two hours later: Just the odd wasp going in, nothing coming out. One day later: Not a wasp to be seen. Two days later: Nothing. The nest is no more. Couldn't be more pleased, so much cheaper than professional pest controllers, and I'm all tooled up should another nest appear in the future, plus I only used about a quarter of the powder.

Took a couple of applications but then worked and cleared away the wasps from their nest under my roof area completely.
