A windblown particle control device which, when attached to the surface of the earth assumes a generally tubular cross-sectional shape, stabilizes particle cover and controls deposition and retention of windblown particles. A sheet of netting material is curved in an arched configuration. Webs of the sheet are linked together to define apertures through the sheet. The apertures create aerodynamic effects in the wind which stabilize, deposit and retain the particles on the earth surface. A kit of components, which includes the netting sheet and a plurality of frame structures to support and maintain the netting sheet in the arched configuration may be employed to assemble the control device for use.
