Rentokil PSW98 Wasp Killer Powder 150g

Used to treat a large Wasp nest in a garden rubbish bag.Product effective after only one application. No wasps to be seen, or heard , after leaving for the recommend 24 hours.

There is no doubt that if you can get it into every entrance this product is very successful. I had an overhead wasp next in my house coming down from the roof. The problem was getting the powder to puff up vertically. You may need a bulb puffer - I filled a plastic hose with powder and blew it up into the nest with compressed air.

very effective but you need to destroy the nest ideally.

This product was perfect for the job, we had a large wasps nest and one treatment killed off the nest.Excellent product .

I had a nest underneath my roof, inside the structure where the roof meets the wall. It was completely hidden from view, all I saw were wasps crawling in and out of a small gap in the timber.I used an old portable pressurized tank with a trigger and a nozzle, I filled the nozzle with powder, jammed it into the entrance to the nest, and blasted away.The next day, there were hundreds of dead wasps all over the place. Haven't seen any around since.Make sure you get a solid direct hit, and it's game over.

I bought this item as it is described as containing the active ingredient "Bendiocarb" which is very effective.The item supplied does not contain this ingredient.

No signs of wasps. Applied the powder week ago. The wasps were nesting in the cavity. I give it three stars because of the process of application was rather awkward ie I had to puff it up aiming at the little hole in the wall which caused some of the powder ending up on the floor and my shoes... This could be easily solved by supplying it with a bottle with applicator or a straw. Also, I didn't know that this is actually same powder as any powder which is half of the price.

I was lucky it was only a tiny wasp nest just started and I'm sure its done the trick, but it would have been extremely difficult had it been a large nest as you have to puff the powder out by squeezing and its harder than you'd think, I wouldn't have risked if it had been a bigger nest. shame there isn't an easier way of applying it as I had powder all over my shed, maybe its just me.
