Earwigs are a common garden pest known for their distinctive pincers and nocturnal behavior. These insects can cause significant damage to plants and crops, making earwig control essential for healthy gardens and farms. One potential solution for repelling earwigs is the use of bloodmeal, a byproduct of animal slaughter commonly used in gardening and agriculture. In this article, we’ll explore the effectiveness of bloodmeal as an earwig repellent and its potential benefits and drawbacks for gardening.

What is Bloodmeal?

Bloodmeal is a dry, finely ground powder made from animal blood, usually from cows or pigs. It’s a high-nitrogen fertilizer that can help boost plant growth and soil fertility. Bloodmeal is also commonly used as a natural pest repellent due to its strong odor and the high protein content that can discourage insects from feeding on plants.

Earwigs and their Behavior

Earwigs are small insects that belong to the order Dermaptera. They prefer moist environments and are often found in garden beds, under mulch, or in other areas with high humidity. Earwigs are omnivores and will feed on both plant material and other insects, making them a threat to gardens and crops.

Bloodmeal as a Repellent for Earwigs

Research has shown that bloodmeal can be an effective repellent for earwigs. The strong odor of bloodmeal is unpleasant to many insects, including earwigs, and can keep them away from treated areas. To use bloodmeal as a repellent, simply sprinkle it around the base of plants or in areas where earwigs are active.

Other Benefits of Bloodmeal for Gardening

In addition to its insect-repelling properties, bloodmeal has several other benefits for gardening. As a high-nitrogen fertilizer, it can help promote healthy plant growth and improve soil fertility. Bloodmeal can also be used as a soil amendment to correct nitrogen deficiencies or adjust pH levels.


Overall, bloodmeal can be an effective natural repellent for earwigs in the garden. It’s easy to use, affordable, and has other benefits for plant growth and soil health. However, it’s important to note that bloodmeal may not be suitable for all gardeners or situations. Some people may find the smell of bloodmeal unpleasant or may prefer to use other natural or chemical earwig repellents. Regardless of the method used, managing earwig populations is essential for healthy gardens and farms.
