I would like to know if humidity and moisture in a old house is related in the presence of following insects: Psocoptera exopterygota,Zygentoma Lepismatidae, Dermatophagoides pteronyssinus, Polydesmida millipedes, Coloptera Anthrenus verbasci L., Coloptera Apionidae, Isopoda crustacea, Blattella germanica L., Siphonaptera. And is there an effective treatment against Psocoptera species? They are resistant against all insecticides. Also, how can I destroy the eggs/larves of insectes in clothing? Even washed by 90 degrees, the eggs are still there. I ventilate dailly and heat the house. Also I (and my cat) have a lot of healthproblems because these situation. Is there a scientific explication for this? A solution? Thank you for you're time and answer, Nikki
