[hoosierdaddy]

Fear mongering was mentioned during this thread, and that is exactly what this stickied warning amounts to.
The warning that are being given here are for the most part completely unfounded, and in some cases, obviously made up assumptions.

If anyone wants to engage in a debate over this we can, but I am telling you that Dichlorvos is not the poison that it is made out to be here.
It is NOT considered a carcinogen for starters...which was one of the first warnings given here. Bullshit.
From one of the gov sites the OP cited:

Many statements the government (and others) provide on the product simply contradict many of the unfounded warnings given here.

Not true. Dichlorvos is rendered completely benign when in contact with water. There is no poisonous residue left on anything by No Pest Strips, and they work by releasing gas, not a solid or liquid.

I also found it interesting that the original poster was the one who suggested it be a stickied post. I agree, but not for the same reason.

OK, Al Gore...there should be no debate, right? Just accept what you provide out of hand?

This is another case of people posting stuff they know nothing about and aasuming thier opinions are correct....if your worried about dichlorvos in your pot you should stop eating then since it's all over your food....
Processing and cooking also removed large percentages of dichlorvos
which may be present on food. For example, wheat with 23.8 ppm of
dichlorvos after treatment produced flour with 4.6 ppm of dichlorvos.
Three months later, the wheat had 2.8 ppm of dichlorvos and the white
flour milled from it had 1.7 ppm. The dichlorvos residue in this flour
after 14 days' storage fell below the limits of detection. Shell
Chemical Company, U.S.A. (unpublished) found that biscuits made from
flour containing 0.35 ppm and 1.8 ppm of dichlorvos had 80 and 60
percent less dichlorvos, respectively. Flour with 9.5 ppm of
dichlorvos heated for 30 minutes at 100°C, 150°C, and 200°C had 0.2
ppm, 0.03 ppm, and 0.02 ppm of dichlorvos, respectively. Rice with 5.3
ppm of dichlorvos had only 0.06 ppm after cooking. Miller and Aitken
(1965) found frying and cooking completely destroyed dichlorvos in the
meat, leaving only products of hydrolysis.

just bought 2 more. no shot pest strips are fine unless maybe your breathing them 24/7.i like to use them for a few days in to flower and 30 days in then remove and put in ziplock.been using em for a while. dichlorvos rocks

[smokadepep]

are they safe to use in an unoccupied room in the house?, it says attics and crawl spaces, but mine are in bed rooms on the same floor, i keep a towel under the door to try and keep it in

[GanjaPharma]

thanks for making this sticky, every tool has its place, and i was thankfull for nopest strips when the borg attacked my mother room, but after reading about deaths during the 50's and 60's from (the more potent version) no pest strips i figured thats nothing i want on my medicine. regular neeming during veg has kept me mite free for years, even the NPS resistant ones cant fight neem.

The major effect of dichlorvos is on the nervous system. Studies on people who were exposed to dichlorvos by breathing air in the workplace containing low levels of dichlorvos have not shown any harmful effects.

Ingesting large doses may cause nausea and vomiting, restlessness, sweating, and muscle tremors, while very large doses may cause coma, inability to breathe, and death.

The second quote could also be used to describe the effects of H2O on humans.

Dichlorvos is safe to use. From what we know today...there would be no way to cause death, unless we were to eat the stuff or something completely out of the question.
And it would take lots of it. Too much water can cause toxicity and death also.

I'd be interested to see what you read about deaths from Dichlorvos.

[GanjaPharma]

hey there hoosierdaddy,
shell chemical used to make NPS also they were sold under the name vapona. in 1979 shell settled out of court over the death of an unnamed young man who died in a trailer; thats also when they were pulled from the shelves in the us (they are still sold in central america in the original strength) . there isnt much official documentation of this as that was part of the settlement agreement but a little googling turns up a bunch of anecdotal stuff about the incident. i did come across this .pdf a while ago that details some lovely experiments with DDVP on cows rabbits and other non-human participants. https://www.google.com/url?sa=t&sourc...r=67p8n327g1th
if rabbits and mice die from inhalation exposure, doesnt it follow that a strip hung in a small closet for hours of heat and light exposure could affect the health of someone opening that closet? or the buds that grow in there? do you think the cdc definition of "used as directed" includes the typical uses in a growroom?

ill see if i can hunt down the 1979 case for you, mebe there is something on the intertubes..that was not a digitized world back then
