Will caked up Drione dust remain effective? I have a feeling that Drione dust will be more effective against bedbugs than Delta dust, but I am worried about moisture causing it to become ineffective.
Your question is really difficult to answer accurately. It will really depend on how much moisture is in the environment where the dust is applied. Drione dust only works if it is dry. Drione dust tends to work just fine without caking in a normal home environment. Both Delta Dust and Drione dust seem to work very well for bedbugs and both take about 3-5 days to kill insects.
