RaidRapid Action Fly & Wasp Killer, Fly Killer Spray For Indoor Use, 300ml

We had a fly infestation when a mouse or rat was poisoned by an upstairs neighbour and died in our wall where we could not get at it. I am not someone who likes to use pesticides unless absolutely necessary, but this was one of those cases. There were quite literally hundreds of them coming in every day. I used this product to blast the gaps in the bricks under the floorboards where they were coming in. The flies that were there died immediately. The ones that continued to emerge died shortly after. And even days later, they seemed to be affected by it, coming out small and sickly, unable to fly. So, yeah. Toxic stuff, but does its job. In time they stopped completely (more likely due drying up at the source, rather than the poison.)The smell is cloyingly floral but still smells of chemical. It's a good effort at making it smell "good" but a bit sickening when it's in your house. During this time we spent as little time in the house as we possibly could, for obvious reasons, and left everything open to air it out whenever we could. But yes, I would recommend it if you're experiencing a bit of a fly-mageddon like we did.

Strong and gets rid of the flys

Ive tried many fly sprays but i always go back to this one.

Great product. Trying to use less of this and more of my home made natural. However at time flies can be persistent in coming indoors at this time of the year.

I've only used this on one fly so far and it did kill it. I thought it would have a kind of chemical smell but it actually smells quite nice!

works ok

Works well just smells a bit leave a window open after use

Very useful when there are a lot of flys about, during the summer.
