An insect barrier system configured for positioning about a tree trunk. The system includes a barrier member having an extending portion which includes an inner edge extending along a plane and an outer edge positioned a distance from the plane. The barrier member is configured to be positioned about the tree trunk such that the inner edge is in sealing engagement therewith and a containment area is defined between the extending portion and the tree trunk. A collection sack is configured to be positioned above the barrier member. A tunnel member having a passage therethrough is positioned such that an inlet opening thereof opens into the containment area and on outlet opening thereof opens into the collection sack.

Devices, methods, and systems having insect guards in devices and systems for aspirated smoke, gas, or air quality monitoring are described herein. One aspirated smoke, gas, or air quality monitoring unit includes a detector module that includes at least one particulate sensing chamber within the detector module and an air inlet connecting the sampling tube to the particulate sensing chamber allowing communication of air from the sampling tube to the particulate sensing chamber; and a spiral shaped insect guard positioned within the inlet.

A moated system for repelling insects. The moated system is a two-part system including a first body having a lip extending substantially perpendicularly along a rim, wherein the rim encloses a central area. A moat channel forms the second body and extends about a lower side of the rim, wherein the moat channel can be filled with liquid to prevent ants from crawling into the central area. A filling port having a funnel is disposed through the upper side of the rim and is positioned directly over the moat channel. The funnel extends into the moat channel to prevent the moat channel from overflowing. In some embodiments, the two-part system is in a configuration of servingware or a pet dish having an interior compartment, wherein other embodiments, the two-part system is utilized along a perimeter of a tabletop to prevent insects from accessing an upper surface thereof.

Mosquito bed net assembly 10a-h includes a mosquito bed net (12) impregnated with a first insecticide and a barrier member 16a-h located above an upper surface (14) of the bed net (12) and being impregnated with a second insecticide. In use, bed net assembly 16a-h increases the likelihood of delivering a lethal dosage of insecticide to mosquitoes flying in frequently-visited areas of a bed net, without increased attendant health risk to a user.

A device for insertion into an open end of a length of pipe to prevent mosquitoes from entering the pipe is provided. The device includes a piece of flexible foam material having a front face, a rear face and one or more edges joining the front face to the rear face. A plurality of indentions, preferably three, are formed in the front face of the piece of flexible foam material to allow a user to quickly and easily grip the device to insert or remove it from the pipe. The piece of flexible foam material preferably comprises open cell foam sized to permit water to flow through while preventing insects from passing through. The device may be used in connection with a system to prevent mosquitoes from entering into a rain gutter drain extension or a rain barrel system.
