Methods of reducing or preventing particulate flow-back in subterranean zones are provided. In accordance with the methods, a treating fluid having a mixture of reticulated foam fragments and particulate solids suspended therein is provided. The treating fluid is introduced into a subterranean zone and the mixture of the reticulated foam fragments and the particulate solids are deposited in the subterranean zone whereby the reticulated foam fragments retard or prevent the flow-back of the particulate solids and the transport of formation fines from the subterranean zone upon the flowing-back of fluid from the zone.
