Quick Answer
To address pest issues in buried living spaces, use a combination of sealing, exclusion, and non-toxic repellents, such as diatomaceous earth or natural essential oils, along with regular inspections and maintenance.
Pest-Proofing Measures
When designing an underground home, it’s essential to incorporate pest-proofing measures from the outset. This includes sealing all gaps and cracks in the structure, using a durable water-resistant barrier to prevent moisture intrusion, and ensuring a tight seal around doors and windows. A minimum of 1/4 inch gap should be left between the door and the frame to allow for thermal expansion and contraction.
Natural Repellents and Traps
In addition to sealing and exclusion, natural repellents and traps can be used to deter pests from entering the space. Diatomaceous earth, a non-toxic powder derived from fossilized algae, is effective against ants, cockroaches, and other crawling insects. Essential oils, such as peppermint and lemongrass, can also be used to repel pests. For larger pests like rodents, humane traps or deterrents like ultrasonic repellent devices can be installed.
Regular Inspections and Maintenance
Regular inspections and maintenance are crucial to preventing pest issues in buried living spaces. This includes checking for signs of pest activity, such as droppings or gnaw marks, and addressing any weaknesses in the structure or seal. It’s also essential to maintain a clean and organized living space, storing food and trash properly, and ensuring good ventilation to prevent moisture buildup.
