Formula ‘C+’ Silverfish Killer Spray 1ltr and Silverfish Killer Powder 300g - Fast-Acting & Long-Lasting Control for Insects, Eggs & Larvae - Professional Strength Approved for Amateur Use

I’ve had a problem with silverfish for a while now. I tried using diatomaceous earth to kill them but they just crawled around in it. I tired cedar oil which did repel them from areas where it was used but doesn’t kill them. I was about to give in and call in a pest control firm when I saw reviews for this product. It’s fantastic. I used the powder in areas where I’ve seen them at night and the next day, lots of dead silverfish (and a few woodlice) were there for me to vacuum up. I saw dead bugs for a few days afterwards and haven’t seen any live ones when I check at night, so I know it’s wiping them out. I plan to use the powder again in a week to ensure any hatched silverfish are killed. I also plan to use the spray in carpeted areas just in case there are any silverfish that I can’t see there.I have dogs, one of which is sensitive to chemicals, so I was careful to keep him out of the treated room and then vacuum the next day. He hasn’t had any reactions to the product so I think dog owners will be happy too.I did have a problem with the applicator in the bottle but the seller sent a replacement promptly. I’m pleased to see such excellent customers service and highly recommend this product and seller.

The powder is a bit messy so mainly used the spray. Haven't seen any alive silverfish in the areas I have sprayed. Alot of dead ones this will definitely be a stable for my household as we were overran ran

I have to say I am so impressed at how well this product has worked at killing silverfish. I noticed some silverfish in crevices in our hall way and tipped plenty of power down. We have actually left the power in the grooves and haven't bothered hoovering it up yet. The powder has worked wonders at killing the silverfish really quickly. It must be so strong that even when it quickly walks onto the powder it starts taking affect, like it's just burnt it or something. We have noticed the dead silverfish lying on the floor and seen the ones wriggling whilst dying.This stuff works 100% and I would suggest to anyone who says it doesn't work, that they need ensure they haven't accidentally mis identified silverfish for a different bug. It has done a brilliant job at killing our silverfish!

After trying a few different sliverfish spray killer/repellent and not seeing much if a result, I was not very hopfully that this product would work. I used the spray first and was still seeing sliverfish. A week later I put the powder down and tried to brush it under the skirting boards as I have young children. The next morning I was finding dead silverfish everywhere. It's been 2 weeks since I put a small amount of powder around the edge of the room and I'm still finding a couple of dead silverfish every morning. I've not seen one alive.Would 100% recommend the powder.

This stuff is amazing it kills the little buggers I had the problem in the bathroom so I put it under the bath section not seen any since what an amazing product

I've used it once and not seen anymore silver fish in my bathroom but it's only been a few weeks. Using the powder is a bit fiddly initially but I got the hang of it in the end.If it has worked than there's a huge amount of powder and spray left over as well.

I still have silverfish coming for party in the night even after few months of use. Maybe they get use to this product

The items were as described. They were delivered promptly. We had been using a spray insecticide from a different company in the bathroom and utility room, being careful to keep it away from food and cooking utensils. Subsequently we had found dead silverfish and some live ones. Therefore we decided to use this product sold through Amazon. On reading the instructions, they do not actually mention for use against silverfish although they are marketed as silverfish killer. We have been using the powder and spray for about ten days. First we decided to use the powder along the skirting boards in the two bedrooms, in the built in wardrobes and a linen cupboard on the same floor as the bathroom. The spray into crevices in the bathroom, utility room and kitchen, being careful to protect food and utensils. We continued to see some dead and one or two live silverfish in various places in the house every day Wherever we find live silverfish we use either the powder or spray as appropriate to the situation. We useWe have been using both the powder and spray as appropriate, along skirting boards and into crevices in our bathrooms, bedrooms, linen cupboard, utility room and kitchen for the past ten days. Always being careful to protect food and cooking utensils. We have used the mask provided to protect ourselves from the powder or spray vapour. We continue to find both dead and live silverfish. The problem as we see it is there are so many nooks and crannies in the house it is impossible to treat every area. We would welcome advice from the seller as we would like to exterminate all the silverfish in our house.
