Earthworms are not insects, nor is there any reason to get rid of them; they are beneficial to the soil. As for other insects, people often use insecticide to get rid of them, but this depends upon the species. To get rid of bedbugs, you have to use heat.

Yes, chlorinated water kills earthworms. The worms in question must breathe through their outer layers. The "skin" needs to be kept moist, but waterlogged, with the consequence that too much of any water -- not just chlorinated -- will kill earthworms.

Yes, a borax solution can be harmful to earthworms. Borax, or sodium borate, is toxic to many soil-dwelling organisms, including earthworms, as it can disrupt their bodily functions and lead to dehydration. While small amounts may not immediately kill them, exposure to borax can ultimately reduce their populations and negatively impact soil health. It's best to avoid using borax in areas where earthworms are present.
Yes, diatomaceous earth can kill earthworms by dehydrating them. However, its effectiveness in controlling their population may vary depending on factors such as application method, environmental conditions, and the size of the earthworm population.
Table, Kosher, and Sea does. Epsom does not. potting soil kills earthworms
Salt is harmful to earthworms and can kill them. When salt is applied to soil, it draws moisture away from the worms' bodies, leading to dehydration. Earthworms thrive in moist environments and require a certain level of moisture to survive, so high salt concentrations can be detrimental to their health. Thus, salt does not feed earthworms but rather poses a significant threat to them.
