Garlic bug spray

The garlic bug spray is effective against aphids and can be used to deter snails and mosquitos, as well. There are store-bought pest control products that are heavily advertised as garlic solutions. It might prove smart to make some on your own and keep a bottle of fresh pesticide in the fridge at all times.

Your plants will be protected if you remember to spray them in the evening with the anti-vampire juice to keep them safe. Spray from at least 15 cm. Note that you need to spray an even coat of pesticide on both sides of the leaves of your plant. Think of it as spray painting.

Wondering how to mix this concoction on your own? There are different takes on it and each has some form of personal twist, here is a tried and tested recipe for garlic spray for plants.

Pepper spray for pests

It turns out that pepper spray is effective against all kinds of attackers, even those trying to harm our plants. The pepper spray can be combined with onion and garlic for better results. It deters rats, mice, stray cats and other mammals. It is also effective against birds.

Soak the leaves of the plants well, and make sure to spray around them. The most important thing is to avoid using pepper spray on plants with fruits or those that are just blossoming, as capsaicin is toxic to bees and other pollinators. The recipe for homemade pepper pesticide you can find here.

Neem oil insecticide

Essential oils are often used in different homemade pest deterrents. You can easily find neem oil extract for sale, as it is largely used by gardeners thanks to its insect deterring effect and the fact that it can prevent powdery mildew on plants. In ancient Chinese medicine, neem oil was used to treat fungus infections and it is still used by some practitioners. In gardening, it is used against a large number of vermin like aphids, mealybugs, whiteflies and others.

The main perk of neem oil bug spray for plants is that it is completely safe to use on fruits and veggies. Neem oil is essentially fatty acids, it is safe for us and our pets and it doesn’t leave any residue in the soil. However, you should be careful with the oil, as it can be dangerous to some plants. Test-spray on a small area and wait for 24 hours, before spraying the entire plant. Spray in the evening and don’t treat the plants more than twice a week.

Here is how to mix up your own homemade neem oil spray.
