Borax and Moth Control – Setting the Record Straight

Jul 25, 2012

Borax is sometimes recommended as a substance that can be used for moth control, but not by, so we thought that we ought to put the record straight about Borax!

Borax is a naturally occurring compound that is often used for laundry purposes and other widespread applications such as buffering in chemical engineering, as a flux for welding and increasingly in gold mining in place of mercury. Borax is toxic and can kill if ingested, even in very small quantities for children and pets, so safety with Borax around the home is paramount. It can affect fertility in humans.

In terms of laundry, borax may work in the right quantities to kill moth eggs. However, its effectiveness is far better at higher water temperatures and it is also a bleaching agent, both good reasons to not use it for knitwear that require low wash temperatures and may not be fully resistant to bleaching.

The other potential use is in dealing with the larvae of moths as a powder – given its toxicity, you may not be comfortable leaving it around the house.  We would strongly recommend that you use organic diatomaceous earth powder, ground from the fossilized remains of marine algae and completely inert (although it should still not be ingested!). You can buy diatomaceous earth from (branded Oa2ki) in either an Oa2ki Aerosol form or as an Oa2ki Powder Puffer – specifically designed for controlling pests such as moths by removing the waxy coating of the larvae and ensuing dehydration.

If you are looking to use borax as a way to control moths in a completely natural way, we feel strongly that the benefits do not outweigh its ‘natural’ label – you might as well use chemical treatments for a hard-hitting and fast resolution to problems with moths – see our Moth Killing Products range for more details (which includes the Oa2ki diatomaceous earth products).
