Abstract
A mechanical insecticide is made by mixing water with at least one type of silane to make a silane solution which is then mixed with diatomaceous earth until there is substantial deposition of the silane material on the diatomaceous earth material, to make a silanized diatomaceous earth. The silanized diatomaceous earth can be diluted with water and applied to vertical and overhead surfaces using a sprayer, for the control of insects. The silanized diatomaceous earth can also be dried into a powder for broadcast application, or mixed as a paste for brush/roller/caulk application.
Claims19
A method for making a mechanical insecticide characterized by the steps of:
- mixing water with at least one type of silane to make a silane solution, wherein the type of silane is one with which an organic substitution can form hydrophobic phases with embedded hydrophylicity;
- and
- mixing natural uncalcined diatomaceous earth with the silane solution,
- wherein the diatomaceous earth has an average particle size of between 1 and 20 microns, until there is substantial deposition of the silane material on the diatomaceous earth material, to make a silanized diatomaceous earth;
- and
- wherein not adding a pest control agent to the mechanical insecticide.
