Chiggers, also known as harvest mites or red bugs, are tiny arachnids that can cause itchy bites and discomfort for humans and pets. Tall grasses, weeds, and wooded regions, offer ideal conditions for a potential encounter with chigger bites. Chigger bites can make you scratch your skin, causing an infection. While there are various methods to control chiggers in your yard, using diatomaceous earth (DE) is a natural and effective solution. In this comprehensive guide, we'll explore what diatomaceous earth is, the habits and life cycle of chiggers, how to identify them, and most importantly, how to use diatomaceous earth to kill chiggers.
Understanding Diatomaceous Earth
Diatomaceous earth is a naturally occurring sedimentary rock composed of fossilized remains of diatoms, microscopic algae with hard shells. This fine powder is rich in silica and possesses remarkable absorbent and abrasive properties. When insects or arachnids come into contact with diatomaceous earth, it penetrates their exoskeletons, absorbs fats and oils, and ultimately dehydrates and kills them. This enables gardeners to use a pest control method without the worry of poisons.
Habits and Life Cycle of Chiggers
Before delving into control methods, it's crucial to understand the habits and life cycle of chiggers:
Habitat: Chiggers live in moist, grassy areas such as fields, forests, gardens, lawns, and tall grass, where their food sources are. They are most active during the warmer months. Typically from spring to fall are ideal conditions for chiggers.
Feeding Behavior: Chiggers are parasitic during their larval stage. They attach themselves to hosts, including humans and animals, and feed on skin cells, causing intense itching and irritation.
Life Cycle: Chiggers undergo a four-stage life cycle: egg, larva, nymph, and adult. The larval stage is when they are most problematic for humans, as they seek hosts for feeding.
Identifying Chiggers
Identifying chiggers is essential for effective control. While these pests are tiny and challenging to spot, there are some signs to look out for:
Bites: Chigger bites typically appear as red, itchy welts on the skin, often with a central blister or pustule. They are commonly found in areas where clothing fits tightly or where skin is thinner, such as ankles, waistbands, and armpits. You can treat chigger bites with calamine lotion or taking an antihistamine.
Habitat: Since chiggers prefer grassy and damp environments, being aware of these areas during outdoor activities can help identify potential exposure.
Lifecycle Awareness: Knowing the times of year when chiggers are most active can also aid in identifying a potential chigger problem.
Controlling Chiggers with Diatomaceous Earth
Now, let's explore how diatomaceous earth can be used effectively for eliminating chiggers and prevent chigger bites:
Application: Apply diatomaceous earth in a thin, even layer in areas where chiggers are likely to be present, such as grassy areas, around trees, and along garden borders. Focus on spots where you suspect chigger activity or where you spend time outdoors. The best way to apply diatomaceous earth, in a lawn setting, is to mix the DE 50/50 with lawn sand or topsoil. Apply evenly and lightly to the point that it is visible. Be sure to reapply if it gets washed away by rain. Reapply every 7 days during the peak season to get rid of chiggers.
Direct Contact: When chiggers come into contact with diatomaceous earth, the powder adheres to their bodies, dehydrates them, and ultimately leads to their demise. Sprinkle diatomaceous earth as needed, especially after rain or irrigation that may wash away the powder.
Personal Protection: When spending time in chigger-prone areas, wear protective clothing such as long sleeves, pants tucked into socks, and insect repellent to reduce chigger bites. If bitten, Calamine lotion works well to help control the itchiness.
Pet Protection: Apply diatomaceous earth to areas where pets frequent, such as pet bedding, outdoor resting spots, and around the perimeter of the yard to help protect them from chiggers.
Environmental Considerations: Incorporate practices to reduce chigger habitats, such as mowing lawns regularly, clearing vegetation around the home, and minimizing moisture in outdoor areas.
Conclusion
Diatomaceous earth presents a natural and effective solution for controlling chiggers and mitigating their impact on outdoor activities. By understanding chigger habits and life cycles, identifying potential infestation risks, and strategically using diatomaceous earth, homeowners and outdoor enthusiasts can enjoy outdoor spaces without the nuisance of chigger bites. Remember to apply DE safely and consistently for optimal results, ensuring a more comfortable and enjoyable outdoor experience for all.
