green leaf after the rain


Last Crawl Insect DE-stroyer is registered for use as an insecticide. For many years individuals have used diatomaceous earth for this purpose and have found that it works well to kill pests such as fleas, ticks, mites, ants, silverfish, bed bugs and most other crawling insects.


Last Crawl is often used inside the house, in the yard and in the garden for pest control. (Please see: APL’s Food Grade Diatomaceous Earth Now Approved in Canada As Natural Insecticide for suggested instructions on how to apply the product.)


While the product is only effective when dry, it can become wet and will continue to function as it did before once it has dried out. In fact, Last Crawl can become wet and dry out an infinite number of times without losing its ability to lacerate and kill crawling insects. Due to the fact that Last Crawl will return to its natural form once dry, the product can be applied wet without decreasing its effectiveness.


Once the product has been applied it will continue to work unless it is washed or blown away. Due to the fact that the powder is very light, be sure to re-apply outside after a rain or wind storm. As well, when used indoors, the powder will need to be re-applied when it no longer appears to be present in the areas of application.
