That Cockroach in Your Kitchen Could Be a Spy

A cockroach moving across a wall may look ordinary, but a German defense startup says similar insects are now being used for military reconnaissance.

SWARM Biotactics has announced that its bioelectronic cybernetic insect swarms have passed field tests and are being deployed by NATO customers, including the German Armed Forces. The systems combine live insects with neural interfaces, sensors and secure communications to create coordinated reconnaissance platforms.

The company fits Madagascar hissing cockroaches with microelectronic backpacks equipped with cameras, sensors and microphones. Electrodes attached to the insects’ antennae guide navigation, while AI-based swarm software coordinates their movement. The insects rely on their natural locomotion, with electronics providing command and data transmission functions.

Chief Executive Officer Stefan Wilhelm said the systems have moved from concept to operational use in about one year. “Swarms of programmable cybernetic insects have been built, field-tested, and deployed by NATO countries. Yes, what you see is real. Living organisms are controlled by bioelectronic neural interfaces, carrying sensors, edge AI, and secure communication,” Wilhelm said.

He added that production scales through biological reproduction rather than traditional manufacturing. “We’re not making a better drone; we’re pursuing a different law of scaling in physical intelligence. Capability is multiplied through biology, not engineering complexity,” he said.

According to the company, the insects can access narrow or hazardous spaces that conventional unmanned systems may struggle to reach, including collapsed structures or confined environments. The small size and low acoustic signature allow discreet data collection in high-risk areas.

SWARM Biotactics has raised more than €13 million and completed field validation in European and U.S. operational environments. The company stated the insects are not harmed and can move normally while carrying the equipment. It plans to focus first on defense and security missions before expanding into crisis response and infrastructure inspection.
