Review: I bought this for to use both indoors and outdoors. We have high ceilings in our home and it's often difficult to reach cobwebs so sprayed this around the home on ceilings, skirting boards and in the porch and it was very effective. I didn't need to reuse for around 3 months. It's has a nice pleasant smell and uses natural ingredients such as peppermint and lavender. It's also humane so doesn't kill insects, spiders and rodents but just deters them. I also used this outside underneath our car on our ABS sensors which sounds weird I know but we've actually had our sensors chewed through by rodents - so far it's deterred them and it hasn't happened again. I will probably redo them every 6 months. A little goes a long way - not many drops are needed but it's useful to have a spray bottle handy to dilute the products and spray around the house. It can also be used in a diffuser or oil burner.
Review: I am petrified of spiders. PETRIFIED. Spider season is upon us, and after an episode of a Spider hidden in a towel and then getting into my hair and falling into my lap, it's safe to say I was looking for protective and preventative measures...I realised a lot of sprays were expensive, and since I use a lot after the trauma of a Spider literally falling out of my hair, I searched for ages until I found this product. It ticks all the boxes for me. It makes up 30 litres, there's a travel spray, it smells divine and natural, and I've not seen the huge ugly spiders for a week since spraying down all the skirtings and hoovering away the webs. I'm spraying multiple times in a week, at least twice, and so far so good. I can finally relax without feeling like a Spider is going to, quite literally, fall out my hair (shudders). It gives me peace of mind and stops me scanning the room for eight legged nasties, and stops me screaming at 5am at big bad brucie the Spider. Will be buying again in the future, many thanks! It is now 2025, and I still use this. We had an estate agent over for a price estimation, and she remarked on how nice the house smelt. When I explained it was anti spider spray she was stunned, thinking it was a posh candle. Nope! Just a reliable natural and trusted anti spider spray! Had one spider incident since, which was due to a puppy dumping the giant thing on the living room rug, but otherwise, nothing!

## Features

- 100% Natural, Humane, Super Kind & Long Lasting - No chemicals and no killers. Our active ingredients are Peppermint, Lavender and Citronella essential oil. Our product repels (they don’t like it!) and does not kill or harm spiders, insects or rodents. It smells nice to us humans though :) No harmful nasties and only completely natural ingredients. Safe for children and animals. Just dilute with tap water. One 50ml bottle will give you a handy spider, rodent and insect repellent for ages & ages.
- Handy Travel Spray - We have included a 3ml spray bottle as a handy ‘quick spray’ option for specific places at home (bedroom window for example) or if you are out and about (flies near your picnic hamper?). Once full it will provide approximately 40 average sprays. One drop of oil mixed with fresh water will do the trick!
- Brilliantly Effective For Home, Garden & Holidays - We use the most effective natural repellents combined in our unique formula. Use around the house, on motion detectors/burglar alarms/CCTV cameras, in the garden, in outside sheds, your garage, in the office, in the car, at picnics, windows, doorways, outbuildings and indeed everywhere you need to! Comparable to DEET and neem oil in effectiveness, but our repellent is more cost effective and less harmful.
