Bat Manure Compost Tea: How to Make and Use Bat Guano Tea

Compost tea—compost extract in dechlorinated water with beneficial microorganisms—has encouraged soil and plant health for centuries. The organic matter source is crucial. Clean compost and worm castings are common bases, but bat guano tea is exceptionally nutrient-rich.

Composting Bat Manure for Tea

Bat dung (harvested dry after composting by guano beetles and microbes, from insect/fruit-feeding species only) is incredibly rich and non-malodorous. Work directly into soil as fertilizer or convert to bat manure compost tea.

Bat guano tea nourishes soil/plants and has bioremediation properties—cleansing soils contaminated by pesticides, herbicides, chemical fertilizers. Foliar application prevents fungal diseases.

Bat Guano Tea Recipe

Bat guano NPK: 10-3-1 (10% nitrogen, 3% phosphorus, 1% potassium). Nitrogen = rapid growth; phosphorus = roots/blooms; potassium = overall health.

Simple recipe: 1 cup dung per gallon non-chlorinated water. (Chlorine kills microbes—let city water sit open overnight to dissipate.) Mix, steep overnight, strain, apply directly to plants.

Complex recipes add: unsulfured molasses, fish emulsion, worm castings, seaweed concentrate, humic acid, glacial rock dust, specific bat guano species (Mexican, Indonesian, Jamaican).

Application: Foliar spray—fine mist early morning or pre-dusk. Root application—apply at root zone, water in. Bat guano tea isn't fertilizer but promotes biologically diverse soil with efficient nutrient absorption, reducing fertilizer needs over time. Use immediately—loses potency overnight.
