Diatomaceous Earth, is it in Bisquick? Does Bisquick contain Diatomaceous Earth? Does Bisquick have Diatomaceous Earth in it?

So I read all over the place that diatomaceous earth is a good way to stop pests. I guess the deal is that it is small fossilized plants and it slices the exoskeleton of bugs that walk across it and then they bleed to death (not a pleasant way to go).

One thing I find interesting is that a lot of sites claim that Bisquick, and other mixes, contain diatomaceous earth (DE) as a pest control.

This site for example on How to keep bugs from entering my house http://howtokeepbugsfromenteringmyhouse.blogspot.com/

Or this one http://www.internet-grocer.net/diatome.htm

So I wrote Bisquick an email because I’m curious if this is true or not?



  1. Hey all DE is made of very, very small particle of glass. Yes, Glass.


    “Natural freshwater diatomaceous earth is used in agriculture for grain storage as an anti-caking agent, as well as insecticide.[5] It is approved by the US Department of Agriculture as a feed supplement.

    It is also used as a neutral anthelmentic (de-wormer). Some farmers add it to their livestock and poultry feed to improve the health of animals.[6] “Food Grade Diatomaceous Earth” is widely available in agricultural feed supply stores. It is acceptable as organic feed additive for livestock.”
