Abstract: An insect trap having an airtight sealing mechanism that can be opened and resealed to turn the trap “on” or “off.

Abstract: The invention relates to attractants for use in yellow jacket traps. The attractants have improved overall effectiveness in attracting yellow jackets, in attracting a broader spectrum of yellow jacket species and in attracting yellow jackets in the several phases of their life cycles when their food requirements vary. The attractants are distinguished by the inclusion of a weak acid in the attractant formulation. The preferred weak acid is acetic acid and its preferred form is a vinegar.

Abstract: There is disclosed a dispersion comprising fluorocarbon resin having a particle size between about 0.05 and 0.5 micron and a viscosity less than about 15 centipoise. The dispersion may contain a freeze/thaw additive, and is suitable for coating surfaces to form a dried film upon which insects cannot climb, alight or make nests or webs.

Abstract: A coating (17) and a method for its preparation are disclosed which will restrict the movement of insects over a skewed surface (15) to which the coating is applied. The coating (17) is an adherent thin film comprised of particles of less than 5 microns. The dispersions are prepared using a surfactant. The surfactant may be removed, at least in part, from the film by leaching or evaporation. The dispersion may also include a dispersing agent which need not be removed from the film. Stabilizing agents may be added to protect the dispersions from freeze/thaw cycles. The coatings (17) are preferably applied by spraying or roller coating the dispersion over the surface (15).

Abstract: Crawling insects are caused to abandon sites they have infested or prevented from infesting other sites by preparing dispersions from selected minus 10 micron particles and forming a film on the surface to be protected. Different insects can selectively be controlled by adjustment of the particle sizes in the dispersion.

Abstract: A dispersion of a polytetrafluoroethylene resin having a particle size between about 0.05 and 0.5 microns, a suspending agent and a viscosity less than 15 centipoise. The dispersion has long shelf life, a reduced tendency to fibrillate and is comparatively stable when acted upon by shear forces and elevated temperatures. The dispersion is well adapted to be sprayed onto surfaces to form a dried film upon which insects can not climb, alight or affix nests or webs. The dispersion can be sprayed without fibrillation dispersion and the dried coatings are adherent, may be washed and remain effective over long periods of time.
