The present invention is an arthropod trap including a housing and containment chamber. The housing includes external openings, an overhang, and an internal tube and plate with entry ports. Attracted by bait in the containment chamber, arthropods fly in through the external openings, and then travel through the entry ports in the plate into the containment chamber. Alternatively, arthropods can directly enter the containment chamber through optional entry ports. The containment chamber can be a box or other rigid container, or a bag. This trap can be used to contain or monitor the populations of many different types of flying arthropods, including but not limited to flies, wasps, and yellow jackets.

A trimmer head for use with rotary vegetation cutting devices is disclosed. The head has a wear guide that indicates when the body of the trimmer head is worn down and needs replacement. In an embodiment of the invention, the body comprises two plates that are molded to fit together. The plates have bores for holding connecting pins. The connecting pins not only hold the plates together, but also pivotably support cutting blades, by fitting into openings in the blades.

A vegetation trimmer attachment head includes a main body, a plurality of elongated blades extending radially outward therefrom, and pins to pivotably attach the blades to the main body. A single pin cover mates with the main body to retain the pins in place. The pin cover is held in place by being interposed between the main body and the vegetation cutting device. The attachment head is simple and can be quickly disassembled and reassembled without tools because it has few parts, none of which are threaded or snap together.
