Strawberry Root Weevil
Otiorhynchus ovatusStrawberry root weevils are small, flightless beetles recognizable by their fused wing covers and shiny, dark reddish-brown to black pear-shaped bodies. While nocturnal adults chew characteristic notch-like holes along the edges of plant foliage, subterranean larvae cause far more severe damage by devouring root hairs and taproots. In late summer and autumn, adults frequently wander into homes seeking sheltered spots to overwinter, posing no structural threat but often surprising homeowners.

Responsible observation
- Nighttime Inspection: Search berry patches with a flashlight after dusk to spot nocturnal adults feeding on leaves.
- Indoor Relocation: Gently sweep up accidental indoor autumn visitors and move them outside into garden beds.
- Ecological Control: Apply entomopathogenic nematodes to moist garden soil to naturally suppress root-feeding larvae.
