A patented insecticidal tarpaulin that stops bark beetle spread directly at the log pile. Field-tested. The only commercially ready alternative after the EU ban on StoraNet.
The Opportunity
Bark beetle outbreaks force forest owners to sell infested timber immediately — flooding the market and crashing prices. The greatest economic loss happens not in the forest, but at the log pile, where harvested wood sits unprotected.
Broad-acre aerial spraying is environmentally problematic and increasingly restricted by EU regulation. Existing point-of-storage solutions offer low effectiveness.
An insecticidal protective tarpaulin — impregnated with a permitted active substance — that covers the log pile and stops bark beetle from escaping into surrounding forest. Applied directly at the point of highest loss.
Simple to deploy, reusable, low cost. The technology was field-tested for 9 months in real operational conditions in cooperation with Lesy ČR (Czech State Forests).
In the Field
Field test conducted October 2019 – June 2020 in cooperation with Lesy ČR (Czech State Forests). 103 m³ log pile, two tarpaulins of 100 m² each. Zero mechanical failure over the full test period.
June 2020 — After 9 months in field conditions. Tarpaulin intact, no mechanical damage.
October 2019 — Installation. Two people, 30 minutes.
October 2019 — Surface detail. Heavy leaf and branch load — no tearing.

Carbon Impact
Bark beetle kills trees and turns forests from carbon sinks into carbon sources. Mediva's solution interrupts that cycle — measurably.
Calculated for Norway spruce per IPCC methodology. Forest absorption rate: EEA 2025.
Market Potential
Revenue potential is derived directly from the area of state and church forests in CZ and CEE — not from an estimated market share in an unknown segment.
Scalable to DE, AT, PL, SK, SE — countries still facing active bark beetle pressure under climate change.
