What is arsenate of lead

[sw282]

DDT was about the only chemical that was effective against bed bugs. lt got banned and now there's a world wide epidemic of bed bugs... These days virtually no chemical available to kill the little blood suckers

If you actually have reason to be concerned about bed bugs there are a few hundred pesticides to choose from that are effective.

Bed bugs are an issue due to high mobility of human travelers more than anything else. They are transported in luggage and clothing items to and from motels, hotels, cruise ships, train berths, dorm rooms. Anyplace people sleep that others also access with their gear and sleep. There is an element of less pesticide use too, for instance we no longer travel with pesticides to treat rooms for these pests, when at one time to do so would have been common. Also there can be a tolerance factor. The bed bugs still alive are decedents of those that survived the harsh chemicals. Making them possibly a bit harder to kill with pesticides. I would guess the cost of professional pest treatment might cause some motels and hotels to skimp a bit on treatment allowing them to be a breeding ground for at least awhile.

DDT was and is great stuff. However I can recall when seeing a hawk or other bird of prey was almost unheard of due to DDT poisoning. Since it was banned these birds are back and it is rare that I don't see one on a daily basis. Balance and moderation are important parts of the process, unfortunately those are the elements that most often get tossed aside in favor of all or nothing approaches.

It would not be useful to add arsenic to an alloy. It would decompose at pot temperatures to the metal oxides.

Chilled lead shot is the best(and safest) source of arsenic.
