Crystal Opus Mouse, Rat & Rodent Deterrent Spray Makes 10 litres. Indoor & Outdoor Repellent. Peppermint Oil Blend with Eucalyptus, Citronella, Lemon, Chilli, Lavender & Clove. Natural Safe Control.

Here’s a breakdown of how each of ingredients of this rodent deterrent concoction works in repelling rats and mice, one by one: 1. Peppermint oil Effect on rats and mice: rats and mice have a highly sensitive sense of smell. Peppermint oil contains menthol, which has a strong, sharp scent that irritates their nasal passages and masks the food smells they follow. Reaction: It confuses, overwhelms, and discourages them from nesting or exploring treated areas. --- 2. Eucalyptus oil Effect on rats and mice: eucalyptus oil has a powerful, sharp odor. Its active compounds (like eucalyptol) are unpleasant to rodents. Reaction: causes discomfort, irritates their nose and possibly their respiratory system, driving them away. --- 3. Citronella oil Effect on rats and mice: while best known for repelling insects, citronella’s strong citrus-like smell is also disliked by rodents. Reaction: disorients rodents by masking food scents and creating an environment that feels unsafe. --- 4. Lemon (oil or peels) Effect on rats and mice: lemon contains limonene and citral, compounds with a strong citrus aroma that rodents hate. Reaction: works similarly to citronella — it irritates their senses and makes an area smell "unnatural" and uninviting. --- 5. Chilli (powder or oil) Effect on rats and mice: chilli contains capsaicin, a natural irritant. Reaction: if inhaled or if it contacts their paws or face, it burns or irritates, making them avoid the area aggressively. --- 6. Lavender oil Effect on rats and mice: lavender has a calming effect on humans but the strong floral scent is unpleasant to rodents. Reaction: it confuses and discourages them, especially in combination with other stronger irritants. --- 7. Clove oil Effect on rats and mice: clove oil contains eugenol, which has a very sharp, spicy scent. Reaction: highly irritating to rodents' sensitive noses; acts like a natural chemical barrier. --- How they work together → When combined, these ingredients overwhelm the sensitive noses of rats and mice from multiple angles — minty, citrusy, spicy, floral, and pungent smells all at once. → This confuses them, hides food scents, irritates their breathing, and makes the space feel hostile and uncomfortable.

Only gave as not sure if works well but we've seen a rat or 2 on occasions but not seen one since .1vweek of treatment. Easy to use product

We had a persistent problem with rats in our loft and tried bait traps ,electronic traps and sonic repellant devices, none of these worked. We then saw your product and thought as a last resort we would try it, WOW!! what a result, the first night there was a lot of activity and we thought the worst, but since then they have gone, no more rats Hooray!. I cannot recommend this product highly enough it does exactly what its says it does, thank you so much it is fantastic.

Not very affective ?

Used this once and haven’t seen rat dropping since and nothing has dug up my flower bed or pooped in my bark. FYI I’m not mingin, the whole areas has issues with explosion in fox and rats, plus the local cat, just defending my area 🤣🤣🤣 Jokes aside, it actually smells good and it’s going to last a while, so very good value for money and doesn’t cause any harm, just puts them off.

Bought two bottles but only used one so far and hasn’t stopped the rats living under my old car. It does have a strong smell but the rat’s obviously love it! Found it a lot cheaper in my local pharmacy too.

Has worked really well so far, sprayed under my bird feeder and even put food on the floor surrounded by the spray to test it. The 1st day 1 young rat appeared, jumped over the food and disappeared into the hedge and neither of the 2 I had have been seen since. They had been coming every day for weeks in broard daylight. It doesn't affect the birds at all. Smells pleasant as well.

Working as described
