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

Absolutely fantastic stuff!!! I bought a flat that had been empty for over 6 months. I first noticed a couple a silver fish while refurbishing. I bought the powder and spray. I've only used the spray on the floors and behind the kitchen sink while the property was completely empty, except for the radiators, lights. The sinks toilets ect were all removed, the silver fish came out of the old radiator. I sprayed all the floors, which were replaced, wood, tiles etc. and I've only seen one or two I've seen since moving in, and they have been dead. Definitely recommend great stuff!!!! My builder told me he's been getting them for years in his own property, showed him this stuff, and he's getting it too

We've been plagued by silverfish this Summer and have tried various traps and potions to get rid of them. This is by far the best and most effective control we've found. The spray is especially good (powder's a bit messy) , and non marking on carpets and flooring. No noticeable smell, and seems to last quite a long time for effect. It would have been five stars but no getting away from it , it's also the most expensive we've tried

I've had silverfish in my bathroom for months and stupidly thought 'oh as long as I keep killing them they'll go away eventually' did some googling before buying this, Silverfish eggs can last from a few weeks to a few years before hatching depending on environmental factors and the Silverfish themselves can live for years, immediately came to Amazon to buy some insecticide for Silverfish and this was the best reviewed one, bought it since it was the best value for money with it having a Spray and Powder, it arrived and I put a generous amount of powder around the skirting in my bathroom, the next day nothing, the day after I notice I haven't seen any silverfish and on the third day it happened, a centimetre long silverfish out in the open dying, nudged it a little with some toilet paper and it moved but not really it was clearly in the process of dying, moved it into the powder for comedic effect, turn around and notice a 3-4 millimetre silverfish dead. So in conclusion the power is an amazing pest control for silverfish, it just takes a few days and those few days the only silverfish I've seen are dead or dying and its a powder so it doesn't stick (unless the surface you're putting it on it sticky, clean your floors and walls if that's the case) and it doesn't smell. Since the silverfish are in my bathroom and I can't put a dry powder in the bath/shower I'll be using the spray on that area but have yet to use it in that way. TL;DR: this duo pack of powder and spray is the single best investment you can make if you have an insect problem and want a cheap, effective, and not that invasive way to bring the all mighty power of death upon those invading insects

Best sprey job done in one sprey but bit strong need to cover nose before start highly recommended as

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.

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 use We 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.

Does exactly what it says. I purchased this item to get rid of silver fish and so far I haven't seen any for a few days in the bathroom.
