Effective Homemade Spider Mite Killer

Introduction - What are spider mites?

Spider mites are somehow related to ticks and spiders, but they are not the same. They are so tiny to be seen unless you use a magnifying glass. Adult spider mites contain 8 legs and are usually red or black. You can find them on the underside of plant leaves.

Spider mites are very dangerous to plants and can cause a lot of damage to your garden within a few days. This means that you need to be very cautious if you have plants in your home. In this guide, we shall reveal the best homemade spider mite killer methods you can use to get rid of them and effective ways to protect your plants from these pests.

What are the effects of spider mites on plants?

 Spider mites may harm your plants in two ways which are;

  • Feeding- These pests suck the chlorophyll plus nutrients directly from the plant’s leaves. The initial stages of their feeding may not be visible and may only appear as a dry spot below the leaf. However, the leaf will change the color to dark yellow or brown when they continue feeding on the leaf while the edges of the leaf will curl and dry off.
  • Webbing damage –Spider mites normally use webbing to keep their eggs safe. They create a web immediately after laying eggs, which prevents water from reaching the plant. This hinders photosynthesis, which is very vital for the plant’s survival, and the plant will eventually dry off.

How do you prevent spider mites from getting into your plants?

When buying plants, it is good to ensure that they are very clean before you bring them to your home. For those plants that you already have in your home, you should do the following;

  • Control the environment- Spider mites thrive in hot and dry areas. Therefore, keeping your plants hydrated is one of the surest ways to keep them off from your plants. Another effective way you should dry is shading the leaves from direct sunlight.
  • Dust the plants off regularly- Dusting your plants will allow you to detect any potential pests before they develop. Always check the underside surfaces of the leaves.
  • Wipe the leaves- You should wipe any suspicious leaf using a wet cloth. Try to do this frequently to ensure that there is no potential spider mite threat.

Top 6 Effective Methods of Eliminating Spider Mites

Spider mites can be very frustrating, especially when they start damaging your plants. If you have been searching for the most effective way to prevent them, you should try any of the following methods.

    Pour all the ingredients into a spray bottle then shake and allow them to mix. Spray the mixture over the plant and don’t forget to spray the underside of the leaves as well as the stem.

    This composition dissolves the spider mites exoskeleton and they usually die because of dehydration. However, you need to be very careful because the mixture may damage the plants. To prevent this, you should spray the mixture in a small portion to see the reaction and if nothing happens to the plants, you can spray the entire plant.
