Abstract
A pest control material (11), such as mosquito netting, has a surface (12) with abrasive/absorptive microprojections (13). Insect pests such as mosquitoes suffer damage to their cuticle, resulting in dehydration and/or invasion by microbial pathogens. The material is made by coating a fabric with abrasive and/or absorptive materials.
Claims26
A material comprising:
- a fabric defining a plurality of apertures there through;
- and
- threads of the fabric disposed adjacent the apertures and having microprojections with uncoated abrasive or wax absorptive surfaces extending therefrom to partially occlude the apertures but allowing light and air to pass there through.
A material comprising:
- a fabric comprising fibers defining a plurality of apertures there through and providing a physical barrier to pests;
- and
- a coating material disposed on the fibers, the coating material comprising microprojections with uncoated surfaces extending proximate the apertures, the uncoated surfaces of the microprojections effective to abrade or absorb wax from an exocuticle of an insect when in contact with the fabric while allowing light and air to pass through the fabric.
A material comprising:
- a fabric comprising fibers defining a plurality of apertures there through;
- and
- a coating material disposed on the fibers, the coating material comprising microprojections with uncoated surfaces extending proximate the apertures;
- wherein a size of the apertures and presence of the microprojections are effective to act as a barrier to insects while allowing air and light to pass there through.

A material comprising:
- a fabric comprising fibers defining a plurality of apertures there through;
- a coating material disposed on the fibers, the coating material comprising microprojections with uncoated surfaces extending into the apertures, the uncoated surfaces of the microprojections effective to abrade or absorb wax from an exocuticle of an insect manipulating through a respective aperture while allowing light and air to pass through the fabric.
