Diatom skeletons are made up of silicon dioxide, a combination of silica and oxygen. Silica is very common in nature and it makes up 26% of the earth&#8217;s crust. Diatomaceous earth is very abrasive to an insect&#8217;s exoskeleton, causing them to dry out and die.&#8221;<\/p>\n<p>Slugs are not killed by diatomaceous earth, though it may slow them down. It is mainly used to control insects with hard exoskeletons. According to the book <a href=\"https:\/\/hortlib.kohacatalog.com\/cgi-bin\/koha\/opac-detail.pl?biblionumber=16389\">Mason Bee Revolution<\/a> (Dave Hunter and Jill Lightner, Skipstone Press, 2016), the abrasive dust can damage the bodies of butterflies, spiders, and some bees by causing severe dehydration; it can also kill beneficial hard-shelled bugs. It is considered a relatively low toxicity method of pest control, usually sold as a dust. However, it is not entirely risk-free: wearing a respirator is recommended. Prolonged exposure can cause <a href=\"https:\/\/academic.oup.com\/jinsectscience\/article\/19\/5\/13\/5586712\">serious problems<\/a> like silicosis).<\/p>\n<p>Using submerged saucers of beer will take care of slugs without adverse consequences for non-target species.
