Pest protection at home

Natural insect protection is also preferred as it protects us from pesky pests in a gentle and health-friendly manner. Standard insect control products contain strong chemicals and biocides that are likely to cause allergies if used regularly. They carry with them a serious risk to human health, which automatically makes them unsuitable in many respects. The good news is that they can now be replaced entirely with homemade solutions containing natural ingredients that will not harm us in any way.

Tip: Making your own homemade fertilizer for indoor plants is a great way to stay away from harmful toxins and chemicals.

Using organic remedies in your home is so important for your family’s health

Protecting your home and yard from mosquitoes

Mosquitoes are one of the biggest carriers of infestations. That’s why we don’t go anywhere without our mosquito spray. But there are plenty of eco-friendly options to protect ourselves from them. These include:

  • Lemongrass – Lemongrass contains mosquito repellent substances as it contains large amounts of both citral and geraniol, both of which repel mosquitoes.
  • Lavender – The scent of lavender chases away mosquitoes. It is the most effective remedy to combat them. Check our guide on how to plant and care for a lavender plant! Moreover, plant this beautiful flower outside, because it is one of the plants that will attract both butterflies and bees!
  • Calendula – Calendula contains tagetone and to lesser extent limonene. Tagetone repels mosquitoes very well just by being present in the garden.
  • Rosemary – This is a well-known culinary herb. It contains Rosmarinic acid along with pinene and borneol, another compound that makes them ideal for mosquito protection. See our guide for taking care of indoor herbs, so you learn how to take care of Rosemary!
