Abstract: An insecticidal polymer matrix containing Piperonyl Butoxide (PBO) and deltamethrin (DM), wherein the ratio between the content of PBO and the content of DM in terms of weight is higher than 3.

Abstract: Dinotefuran and PBO is used for killing mosquitoes, as PBO increases the knockdown speed of Dinotefuran.

Abstract: An insecticidal barrier (1) having an upper net part (2) with a mesh size preventing insects, for example mosquitoes, to transverse the barrier, the upper net part (2) having a first content of insecticide. In addition, the insecticidal barrier (1) has a lower part (3) with an insecticidal fabric, tarpaulin, foil, woven or knitted fabrics or non-woven, or net with a net material having a higher tear strength than the net of the upper part (2) in order to make the lower part (3) of the net more durable.

Abstract: An insecticidal polymer matrix containing HDPE (high density polyethylene), LDPE (low density polyethylene), preferably containing PBO (Piperonyl Butoxide) and DM (Deltamethrin), wherein the ratio of the contents of HDPE to LDPE is between 5 and 20 and most preferably between 8 and 10. The matrix is highly useful for bed nets against mosquitoes.

Abstract: A room for humans or animals, the room comprising a first object and a second object remote from the first object, the first object comprising a first releasable insecticide against a target insect, the first insecticide having a certain probability for inducing resistance against the insecticide among the target insects, the second object comprising a second releasable insecticide, the second insecticide being configured for insecticidal efficiency against the target insect despite resistance against the first insecticide.

Abstract: An insecticidal thread comprising a first type of filaments and a second type of filaments according to the invention. The first type of filaments has an insecticide or a synergist or both incorporated in a polymeric material of the first type of filaments. The second type has an insecticide or synergist or both incorporated in a polymeric material of the second type of filaments. The content of insecticide or synergist in the second type of filaments is different from the content of insecticide or synergist of the first type of filaments. Alternatively, the thread is an extruded monofilament with a first and a second part with insecticide and/or synergist.

Abstract: An insecticidal barrier (1) having an upper net part (2) with a mesh size preventing insects, for example mosquitoes, to transverse the barrier, the upper net part (2) having a first content of insecticide. In addition, the insecticidal barrier (1) has a lower part (3) with an insecticidal fabric, tarpaulin, foil, woven or knitted fabrics or non-woven, or net with a net material having a higher tear strength than the net of the upper part (2) in order to make the lower part (3) of the net more durable.

Abstract: An insecticidal barrier (1) of a non-living material comprising a first region (7) and a second region (8), wherein the first region comprises a synergist and the second region comprises an insecticide but no synergist.

Abstract: The present invention relates to a process—as disclosed in WO 01/37662 for the impregnation of a non living material, for example a fabric or a netting, so as to impart insect killing and/or repellence properties. The process involves the preparation of a solution of an insecticide and a film forming component reducing wash off and degradation of the insecticide, wherein said film forming component comprises a polymeric backbone fixative polymerizing into a film with polyflourocarbon side chains on the polymeric backbone in a drying and curing process of the non-living material. It has been found that the risk for precipitation of the insecticide in the solution of the insecticide is reduced if the insecticide is dissolved in a solvent combined with alcohol or glycol having a water content of less than 5%, and/or the insecticide is dissolved in a solvent and mixed with a water phase emulsion or solution having a temperature of less that 30° C.

Abstract: A fluid filtration device having a fluid inlet and a fluid outlet and a confined fluid path between the inlet and the outlet through a microporous filter with a pore size adapted for filtering microbes, for example bacteria and virus. The device comprises an antimicrobial source, preferably halogen source, adding antimicrobial substance to the fluid in the confined fluid path between the fluid inlet end the microporous filter in order to prevent biofilm formation in the microporous filter.

Abstract: A method for filtration of fluid, primarily liquid, with fluid filtration device haying a fluid inlet and a fluid outlet and a fluid path between the inlet and the outlet through a microporous filter with a pore size adapted for filtering bacteria or bacteria and virus by mechanical particle size separation. The filtration device comprises further an antimicrobial source adding antimicrobial substance to the fluid in the fluid path between the fluid inlet and the inlet surface of the microporous filter. The fluid filtration device is provided with a design flow through the device, the design flow assuring a proper filtration of the fluid flowing through the device with a cleaned fluid at the flow outlet.

Abstract: Liquid dispenser or water purification unit with a housing and a mouthpiece configured for contact with the mouth of a person, wherein at least part of the housing or part of the mouthpiece or parts of both have an antimicrobial surface.

Abstract: A portable water purification unit in the form of a stiff, tubular housing with a first opening at a first end for entrance of water into the tubular housing and a mouthpiece at an opposite end. The tubular housing comprises at least a first module and a connected second tubular module containing mutually different water purifying granular resins. The first module or the second module have at least one water permeable mesh with a mesh size smaller than the grain size of the resins for preventing mixing of the resins.

Abstract: System for separating particles from an environment, the system including a perforated screen and an ionisation electrode in the environment for creating an electrostatic potential between the electrode and the screen to attract the particles to the screen.
