Test Account Posted August 5, 2018 Share Posted August 5, 2018 I have finally (sigh) captured a roll of window screen! Bad news: it was contaminated with plant-derived "eco-friendly" insecticide (the "ecofriendly" ones are arguably worse than the others)! After several rounds of frantic soaping, the nauseating smell of aromatic plant oils is still there. Any ideas, roachworld? Thanks in advance Quote Link to comment Share on other sites More sharing options...
Xenoblatta Posted August 5, 2018 Share Posted August 5, 2018 Wow! I'm so sorry @Test Account I have lost insects for those horrible pesticides already... Maybe cleaning with vinegar + sodium bicarbonate diluted in some water? Is what I use to eliminate pesticides in the fruits before offer to my roaches... ? 1 Quote Link to comment Share on other sites More sharing options...
stanislas Posted August 15, 2018 Share Posted August 15, 2018 Most likely it contains permethrin. That stuff is quite persistent. I would put it in a washing machine with sodium carbonate instead of detergent and wash it a high temperature. Perhaps that will do, as permethrin hydrolyses under alkaline conditions. Another option is the combination of water and light... but that might take time. Even then, I would be reluctant to use it. Considering the fact that permethrin treated clothing can outlast many washing cycles.... 1 Quote Link to comment Share on other sites More sharing options...

stanislas Posted August 28, 2018 Share Posted August 28, 2018 I always peel fruits before I give them to the roaches... Or when possible use those from my own garden. @Xenoblatta: these roaches died after eating contaminated fruits? 1 Quote Link to comment Share on other sites More sharing options...
Bugboy3092 Posted August 31, 2018 Share Posted August 31, 2018 I’m not sure if it may or may not destroy the screen, but as my saying goes, “just burn it”. Supposedly many plant oils can be burned to be removed, for instance, many nuts containing oils (especially peanuts, and they contain tons of oils) are flammable for this reason, so there’s a chance it’d destroy the chemical/decay it to a harmless state.

Yes, they died shortly before this picture, and some hours after offering non-pealed fruits.... ? Quote Link to comment Share on other sites More sharing options...
