Garden Insect Control


*DEBug is used to kill and control sucking, chewing and crawling insects.

Diatomite is used as an insecticide, due to its abrasive and physico-sorptive properties.  The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons. By cracking open their joints and by rubbing holes through their outer shellsm the bugs die quickly, since the holes let air in and let out moisture from the insects’ bodies causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat insects. There is no build up or chemical residues, and insects will not become tolerant or build up immunity.

It is a mechanical insect control - upon contact, the fine powder absorbs lipids from the waxy outer layer of the exoskeleton and causes the insect to die from dehydration. Great for slugs, snails, aphids, caterpillers, earwigs, beetles, fruit flies, borers, thrips and more....  

There is no plant or livestock with-holding period.

* DISCLAIMER: The Ministry of Primary Industries have provided the following statement in relation to DEBug. '...the agricultural chemical use of diatomaceous earth has been proposed to be put forward as an exempt category at the next Regulation change. In the meantime, the ACVM Group will be working on a modified ACVM registration type for this kind of situation with very limited information requirements. Until this is in place, the product may be imported and used in New Zealand as if it is exempt from registration, as long as the applicable conditions in Regulations 7 to 13 of the ACVM (E&PS) Regulations 2011 are complied with, but this is only for the claim for use on or around plants'.
