Yes, Diatomaceous Earth (DE) can kill termites by dehydrating them upon contact, but its effectiveness is better suited for minor infestations or preventive measures rather than severe infestations.
The effectiveness of Diatomaceous Earth (DE) is primarily suitable for minor infestations because:
- DE can directly contact and dehydrate termites on the surface in smaller infestations, contributing to its efficacy.
- Studies indicate that DE’s impact on termites tends to be more pronounced in situations with fewer termites to target.
- Real-world experiences align with this, as DE often yields better results when dealing with limited termite activity.
- As infestations grow in size, the number of termites hidden within wood or soil can make it harder for DE to reach and affect them.
- In extensive infestations, DE may not provide sufficient coverage to effectively control the termite population, emphasizing the need for professional treatment.
What is Diatomaceous Earth?
Diatomaceous Earth, often abbreviated as DE, is a natural substance composed of the microscopic remains of ancient aquatic organisms called diatoms.
These diatoms left behind fossilized deposits in sedimentary rock layers.
DE is primarily made up of silica, a mineral found in sand and glass. It’s this silica content that gives DE its unique properties.
Common Uses and Properties of DE
Common Uses of Diatomaceous Earth
Pest Control: DE is widely used as a natural and non-toxic pesticide to control various pests, including insects like ants, roaches, and fleas.
Gardening: Gardeners use DE as a soil amendment to improve drainage and aeration. It can also help deter pests in gardens and around plants.
Pool Filtration: DE is used in pool filters as a filtration medium to remove impurities and particles, keeping pool water clean.
Food and Beverage: Food-grade DE is used as an anticaking agent in food products like flour, sugar, and grains to prevent clumping.
Properties of Diatomaceous Earth
Absorbent: DE has high absorbent properties, effectively soaking up moisture and odors.
Abrasive: DE is abrasive in nature due to its fine particles, making it useful for polishing and cleaning purposes.
Porosity: DE is highly porous, which contributes to its ability to absorb liquids and trap small particles.
Chemically Inert: It is chemically inert and safe for human and animal contact, which makes it a preferred choice in various applications.
How Does Diatomaceous Earth Work Against Termites?
Diatomaceous Earth is an effective insecticide because of its physical and abrasive nature. Here’s how it works:
Microscopic Abrasion: DE consists of tiny, sharp-edged particles resembling shards of glass. When termites come into contact with DE, these particles stick to their exoskeletons, which are the hard outer shells that protect them.
Exoskeleton Damage: The sharp edges of DE particles scratch and puncture the termites’ exoskeletons. This damage disrupts the termite’s ability to retain moisture and protect itself from external threats.
Dehydration: As the termite’s exoskeleton is damaged, it begins to lose moisture rapidly through the wounds. This leads to the termite becoming dehydrated, which can be fatal.
Absorption: Diatomaceous Earth is also highly absorbent. It absorbs the oils and fats from the termite’s body, further exacerbating the insect’s dehydration and eventual death.
So,
- DE particles are incredibly small, often ranging from 10 to 200 micrometers in size.
- The sharp edges of DE particles are so hard (rated 7 on the Mohs scale) that they can easily scratch through the protective waxy layer on the outside of many insects.
- In studies, DE has been shown to be effective against a variety of insects, including termites. However, its success rate can vary depending on factors like humidity and the thickness of the insect’s exoskeleton.
- DE can dehydrate and kill termites in dry conditions within hours to a few days after contact.
- Keep in mind that while Diatomaceous Earth can be a valuable tool in termite control, it’s often used alongside other methods for a more comprehensive approach.
