Archive file. An archive file is a file that is composed of one or more computer files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption.
Sevin (tm) Insecticide. Sevin is the trade name for a widely used synthetic insecticide containing the active ingredient carbaryl. Carbaryl belongs to the chemical class called carbamates. As insecticides go Sevin is only moderately toxic to mammals and is still widely used in gardens and landscapes.
All insecticides are capable of killing bees, but Sevin dust in particular is bad because it can be carried back to the hive on the hairs of the bees and wipe out the whole hive. The bee population is way down this year, and it is causing a lot of worry because they are our best pollinators.
