I have a problem with slugs in my garden. I tried the cans of beer, but they attracted bees (including a mason bee) and flying ants, but no slugs. So I decided to try diatomaceous earth (DE). This all-natural flour-textured substance has many uses around the home including:
- causing slug, maggot, and insect death in the garden and landscape
- solving an ant or bedbug problem in your home
- getting rid of fleas on pets and livestock
- worming of pets and livestock (and humans)
Diatomaceous earth is made from the silica-rich shells of diatoms. Most diatoms are found in the ocean, but food grade DE is made from freshwater diatoms, mistakenly called ‘algae.’ This is the same brown or golden algae that grows in fish tanks.
I learned from a piece on the local news recently that diatom algae grows on rocks at the bottom of the Clark Fork River in Missoula. And I suspect it also grows on rocks at the bottom of the Swan and/or Flathead River, which means we would have a local source when we can no longer import it from a distant source. All we’d have to do is figure out how to harvest and clean it. Does anyone have any ideas on this? (more…)
