This headline sounds like something out of a classic online cookbook or a viral social media video. When someone claims something works “in less than 10 minutes,” it’s usually a quick home remedy trick using strong, natural scents that insects simply can’t detect.

And as for the mysterious “corn crake,” you’re probably referring to the common mole cricket (Slovak: krtonôžka, often called kukurikár or gargalica). This large, menacing-looking insect burrows into the soil and nibbles on the roots of vegetable plants.

Here are the most common natural remedies that repel flies, mosquitoes, and moles in no time:

Coffee Grounds Trick (Works in 10 Minutes)
This is the ultimate insider tip for getting rid of flying insects quickly.

Here’s how: Place dry coffee grounds on an aluminum plate or foil and light them (optionally with a bay leaf).

Effect: The coffee grounds don’t burn openly, but smolder. The resulting strong, aromatic smoke paralyzes mosquitoes and flies, driving them away from the patio or room within minutes.

Cloves and Lemon (A classic remedy against flies and mosquitoes)
Here’s how: Halve a lemon or lime and insert whole clove buds into the pulp.

Effect: The combination of citrus scent and eugenol from the cloves creates an impenetrable scent barrier for flies and mosquitoes. As soon as the lemon or lime heats up, it releases an intense fragrance. 3. How to get rid of the European corn borer (mole beetle) without chemicals?
Mole beetles live in the soil. Coffee smoke only works if you drive them into their tunnels. But there are other quick tricks for the garden:

Soapy water or oil: If you spot a mole beetle’s entrance in your flowerbed, pour in water with a little dish soap or vegetable oil. The beetle will come to the surface within minutes, as the liquid clogs its airways (then it needs to be collected).

The smell it hates: Mole beetles hate the smell of marigolds, garlic, or eggshells. A strong garlic infusion poured into the tunnels will drive them away immediately.

You’ve probably seen this recipe in a video before, where it was recommended to burn coffee grounds or use garlic cloves as a base. Do you want to protect your patio from flies or save your flowerbeds from mole beetles?
