From a mixture to help ward away spiders from a frightened daughter, or making up our own antibacterial washing machine drops, to a blend to help after a bad cold. So one day we thought... why not share what works for us with the world (well some of it!) rather then just those people we know? Thus, Crystal Opus was born :) Our Essential Oil Range Visit the store Our Essential Oil Range Visit the store ## Features - Use biocides safely. Always read the label and product information before use. - Concentrated Solution. 100% Natural, Humane, Non-Harmful, Super Kind & Long Lasting - No chemicals and no killers. Our active ingredients are Eucalyptus, Citronella, Peppermint, Lemon, Chilli, Lavender and Clove essential oil. Our product repels (they don’t like it!) and does not kill or mice, rats or any rodent. 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. - As well as Mice and Rats our blend is also a repellent against Shrews, Squirrels, Badgers, Hedgehogs, Voles, Beavers, Dormouse, Apodemus and Bats. - Brilliantly Effective for Home & Garden - We use the most effective natural repellents combined in our unique formula. Use around the house, in the garden, in outside sheds, walls, your garage, in the office, in the car, at picnics, windows, doorways, lofts, outbuildings and indeed everywhere you need to! Comparable to poisons or chemical based solutions in effectiveness, but our repellent is more cost effective and less harmful. - Repellents only work well with frequent use and by reapplying regularly. Our long-lasting concentrated formula has been designed specifically with this in mind. One 30ml bottle will give you a handy rodent repellent for ages & ages. Use Indoor or Outdoor. SHAKE WELL BEFORE USE FOR BEST RESULTS. - Rodents are notorious for causing damage to a wide variety of cars, boats and other vehicles. Once inside, rodents can chew through electrical cables, fuel lines, and insulation materials. Modern vehicles are especially at risk, as many manufacturers use soy-based wiring insulation, which rodents find particularly appealing. The damage caused by gnawing on cables can result in electrical malfunctions, short circuits, and even safety hazards such as brake or airbag failures. In addition, rodents may build nests or store food within the vehicle, leading to further issues like clogged air filters or fire risks. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C1HBMT2T | | ASIN | B0C1HBMT2T | | Best Sellers Rank | 3,900 in Garden ( See Top 100 in Garden ) 96 in Rodent Control | | Brand Name | Crystal Opus | | Country Of Origin | China | | Country of origin | China | | Customer Reviews | 4.0 4.0 out of 5 stars (771) | | Customer reviews | 4.0 4.0 out of 5 stars (771) | | Global Trade Identification Number | 15060705810795 | | Guaranteed software updates until | unknown | | Included Components | Cedarwood, Peppermint, Lavender, Citronella, Clove, Rosemary, Thyme | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Form | Oil | | Item Volume | 30 Millilitres | | Manufacturer | Crystal Opus | | Manufacturer | Crystal Opus | | Manufacturer Part Number | rodentrepellent | | Manufacturer reference | rodentrepellent | | Material Features | Cruelty Free, Natural, Non Toxic | | Number of Items | 1 | | Package Dimensions | 8.7 x 3.7 x 3.5 cm; 30 g | | Scent Name | Peppermint | | Size | 30 ml (Pack of 1) | | Target Species | Mouse, Rat, All Rodents | | Unit Count | 30.0 millilitre | ## Product Details - **Brand:** Crystal Opus - **Item form:** Oil - **Item volume:** 30 Millilitres - **Material feature:** Cruelty Free, Natural, Non Toxic - **Scent:** Peppermint ## Images ![Mouse, Rat & Rodent Deterrent Spray Makes 10 litres.

Tiay** A: I made up a small amount of concentrated repellent and soaked a few old tea bags and sprinkled them around where I had seen the rat. Saw it once more and then not again. At least 3 weeks now. It can also be sprayed outside with no harm to domestic animals or in my case hedgehogs who dont seem to mind the smell, which I find very pleasant **Q: Will this work on squirrels invading my plant pots** A: Hi Jools and thank you for your question. We make a specific squirrel repellent. I'm pretty sure links are not allowed in question responses so if you search for 'crystal opus squirrel' on Amazon that should find it. Please let us know if we can help further. Best wishes, Rob ## Frequently Bought Together - Rat & Mouse Repellent Spray. Makes 10L. Super Effective. Child & Pet Safe.
