Presumably it is just badly designed or built. I overcame the problem by cannibalising the squirting mechanism from an almost empty spray of similar design and fit. Of course, that works so that you can use the contents but doesn't address the design. I was going to complain until I realised what a common fault it was with the product and concluded that it was no use knocking if there's no-one in! Best wishes Fontes **Q: Can it be sprayed on leylandi** A: 0To kill spiders on the trees? or to kill the trees?- I think it only does spiders. ( Elsan, camping toilet bleach on the roots, will kill leylandi) **Q: i sprayed this around the flat very generously, do you think if there was any spiders around they would have come out to run for their lives?** A: It deff kills spiders , if you spray them directly. Not sure how long it lasts as a deterrent. **Q: Is it safe to use the moth killer in your bedroom?** A: Save to use anywhere. ## Customer Reviews ### ⭐⭐⭐⭐⭐ fleas gone *by J***N on 3 November 2017* Nasty fleas gone after one use.

After I had my cats treated for fleas, I found them in almost every room, even those my cats had never been in. I didn't have high hopes but I sprayed every surface I could. Within days I hadn't come across a single flea. I spray every 6 weeks as the instructions say and haven't found a single flea in months. ## Frequently Bought Together - Karlsten Flea Killer Spray - Fast Acting Elimination of irritating Fleas | Pest Control kills on Contact | Formulated for Use On Fleas Indoor and Outdoor Flea Spray Killer - 500ML - Johnsons 4Fleas Tablets for Cats and Kittens, 6 Treatment Pack, 14D083 - Johnsons Vet 4 Fleas Room Fogger Spray Twin Pack 100 ml, 2 count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/52802688-karlsten-flea-killer-spray-fast-acting-elimination-of-irritating-fleas](https://www.desertcart.com.ar/products/52802688-karlsten-flea-killer-spray-fast-acting-elimination-of-irritating-fleas) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-04*
