Can your plants OD on Hot Shot No Pest Strips?

[kalikush]

I have a very small cab, like 2'x4'x3' total for veg and flower chambers and I want to toss some of these in on the next dark cycle of 12hrs. I do have some gals about 4.5 weeks into flower. I am going to shut off the ventilation so the pest strips can penetrate every inch of the cab but if I use 3 total for this small of an area and leave them for the entire dark cycle of 12 hrs, could that be too much? I do not want to leave these there permenately but would like to use today then do it again in 3-4 more days for 2 weeks. Would that be too much exposure for some flowering babes that it might damage them?

Well, No Pest strips contain Dichlorvos (DDVP) and are carcinogenic: I certainly wouldn't use them with any plants I intended to consume, especially to smoke them:

No-pest strips may seem innocuous, but they emit continuous vapours of DDVP ( the active ingredient used in most strips ), a highly carcinogenic chemical associated with an increased risk for all types of cancer in children and adults alike, according to the EPA. People who use these strips as directed and are exposed to them over a lifetime have a greatly increased chance of getting cancer. This can be as high as one in one hundred, which is ten thousand times the risk that the EPA considers to be of significant concern.

The EPA also estimates that members of a household using the pest strips face a cancer risk ten times greater than even pest control workers who apply DDVP thousands of times a year without wearing protective clothing.

You don't seem to have mites, so why even consider No Pest Strips? (even if you were to sell the buds to other people, which would not be good karma anyway)

i would never put one of those strips in my actual grow room. i put one outside of my grow room about 15 feet away. having it outside my grow room killed all the fungus gnats and thrips i was getting trashed by after 4 days. then i removed the strip and threw it away. haven;t had any bugs back since. i got the damn buggers from a clone i picked up at the co-op... bullshit!! i always spray my plants down with water 2 weeks before i harvest... i used the strips waaay before i harvested and i'm really not worried about it.

Well, No Pest strips contain Dichlorvos (DDVP) and are carcinogenic: I certainly wouldn't use them with any plants I intended to consume, especially to smoke them:

There are no studies that point to, or evidence of, dichlorvos being a carcinogen.
DDVP is widely used as an insecticide in the foodstuffs and green house industries. Not toxic, and water neutralizes it completely. As a result, it is not a very effective outdoor treatment.
I use it indoor with every confidence.

I havent seen mites on the nuggs yet but I saw their presence on my clones in the next chamber. I want to use this like a fogger because these should release chemicals, fill up the chambers, kill every living thing in the chamber except the plants? then I'll vent outside and seal the strips up for storage.

I read in another thread that Dichlorvos has a half life of only a few days topps! so my plan may work with little risk. I would never use something like this on a 24/7 basis so close to other life though..




How long do you think it would take to kill all bugs in such a small chamber with 2-3 of these strips? 3-5 hours? Or a full 12 hour dark cycle?

 

[TGT]

I use them in the beginning of my grow as a percautionary measure. My rooms are usuall really large so when the plants are just triggered I put about 4 of them in and leave them in there for a couple weeks. Also, I put one in the veg room. Usually this gets me far enough into the grow to be pest free until finished and also gives them some time to air out. I wouldn't use them just before chopping as they are very dangerous if used wrong and I woulldn't want to poison enyone by leaving them in the room until done. Using them this way I believe to be safe and I have not had a pest problem for years since using them. There is a lot of bugs in my area unfortunately and without these I would be having many problems.

[iLLperception]

I had tried the strips while still running my ventilation and they did nothing. Once I turned off the vents (during the night cycle) and put 4 strips in the 5x5x8 room I started seeing results. I would remove the strips every morning and put them in a sealed ziplock bag and then put them back in the room right before the night cycle and turn off the vent fans. I did this for 2 weeks before it killed all my mites, but it did finally work 100%. I stopped treatment about 4 weeks before harvest to make sure any chemicals were gone (at least I HOPE they are gone!).

 

[Maj.PotHead]

KK in your small cab 1 no pest strip should be just fine i havent batteled the brog as there called in long time. they'll die fast w/in 1 wk it takes longer then just 12 hrs no need to turn off ventilation. just place the strip in the cab where your fans can blow it around for few days to 1 wk. spider mites have a life cycle just like soil gnats approx 2 wks but they breed like cock roaches, 1 no pest strip will kick thier buts. for soil gnats use 1-2 inch of perlite or green gardening sand on top of soil this prevents soil gnats from compleating thier life cycle. which is larve hatch and grow in soil craw to surface fly around breed then female lays larve in soil. cycle repeates untill above method is used for very bad infestations use green sand or perlite and no pest strip. when your done batteling the mites with the pest strip there will be alot left i use a large ziploc baggie to hold it. and place in my garage on a high shelf untill ever needed again


dont use this no pest strip last 2-3 wks before harvest you'll have n/p

Ya don't think so hoosier?

Your government agency, the Environmental Protection Agency has studied Dichlorvos, and has concluded the following:

EPA has classified dichlorvos as a Group B2, probable human carcinogen

Abstract
On the request of the Belgian Health Council, the authors performed a systematic review of the available evidence in the literature and in expert panel reports, with regard to a possible carcinogenic effect of dichlorvos. Following the evaluation procedure developed by IARC, they first concluded that dichlorvos should be classified as a possible carcinogen for man.

http://www.sciencedirect.com/scienc...serid=10&md5=49d599f9a500632d82581072960dd539

The so-called "safety" of dichlorvos may have been based on articles appearing in the journal Mutation Research in which scientists were reported to "down-play" the cancer risk. However, as stated by the scientists in this more recent research paper (pg.158):

"Different views on the carcinogenicity data have been published; most indicate that the earlier studies were inadequate (2 references pg.158) flawed (1 reference pg.158) or showed unequivocal carcinogenicity (2 references pg.158). According to the EPA (using all the available data) "dichlorvos has been classified as a carcinogen based on oncogenic effects in mice and rats (1 reference pg.158)...... Increased incidences of mononuclear cell leukemia was observed in dosed male and female rats. In the male rats the increase in incidence was dose-related and statistically significant. Incidences of multiple fibroademonmas were seen in 9 exposed female rats whereas none were observed in the controls.

There are other ways to combat bugs rather than use this:

1) Have a sealed room with a filtered intake

2) Keep your growroom clean

3) Use the environment against the bugs; keep airflow up, mist regularly until full flowers are formed, keep temps moderate

4) Don't go outside near bugs then straight into the growroom with the same clothes; take a shower and wear clean clothes

5) Don't accept clones from a potentially dodgy source



If you still get mites, which is unlikely, and they are the worst, then try everything else, including predator mites, before even considering chemicals.

For a small cab the typical thing man, is to put it in for a day, two days; then remove it, wrapping it in a plastic bag, and replacing it in it's original container.

If you can save the original plastic container you'll notice it doesn't have the same physical characteristics as a regular baggie; that's because it's made to block gas effusion through it, so it can serve as a potency preserving membrane.

Carefully snip the top off that, replace it back in it, then wrap THAT in a baggie, replace in the box till next time.

It's poisonous stuff; you're not supposed to breathe it; you're definately not supposed to touch it, or ingest it, and you should use the common sense anybody in the modern world using synthetic chemicals should. It's not a 'basically harmless' substance; but, it is death to all mites without fail. People report all mites dead in 24 hours regularly.

There will ALWAYS be hot shot's in every grow I do.Since using them nothing has plagued my grows,nothing.........ps,the list of things that can cause cancer is HUGE.....even the air in L.A!!!!!!!DDVP isnt absorbed by the plant,and I dont think you can get cancer from smoking weed were hot shots have been.imo

 

[Dr.Smitty]

I've used them in the grow room and the greenhouse with no human problems but they put the hammer down on any pest problems. No worries!

 

[hoosierdaddy]

BB, I realize that there have been studies made such as a couple you have referenced, that made the pre-study conclusion that Dichlorvos should be coined a carcinogen. However, none of the formal studies that have been done, including the ones you referenced, remain conclusive that Dichlorvis is in fact a carcinogen.

Anything coming within 1500ft of the California state line is considered a carcinogen. Especially if you can place the word "chemical" anywhere on it's label.
Rule of thumb for enviro wacko Americans, is to label as a carcinogen first, and ask all questions later. Saccharin is a classic example. And another good move of our enviro watchdogs was to rid the world of DDT...which has attributed to the deaths of scores of millions in third world countries.

MTBE is another chemical recently banned by the US, and only after an initial ban by California (the leader in banning substances for no good reason). It's been confirmed that MTBE can indeed be tasted orally after it has come in contact with the skin...so it must be a carcinogen, yes? Besides, it is a chemical...and we all know all chemicals are carcinogens, yes? And we should warn people about these dreaded carcinogens each chance we get, yes?

Although MTBE remains on the ban list...saccharin has been removed, them placed back on, then removed again.
Thing is, we are dealing with "the sky is falling" numb skulls, who must come up with terrifying results from their studies, lest no more good study money befall them.
Most of late have switched to the "Global Warming is caused by man and is our sure doom" bandwagon, as there is loads more cash there at the moment.

Used responsibly, and within reason, chemicals have saved our societies as we know them.

Now I'm sure that there will be many a grower run out and eat about 15 no pest strips because they read me say they were safe to use...I say bon apatite!

 

[Wait...What?]

Red M&Ms. 'Nuff said.

Not only do I use No-Pest strips, I use pyrethrin too. So there! Take that!

You'd rather smoke spider mite eggs?

 

[British_Bulldog]

There are no studies that point to dichlorvos being a carcinogen

.......

....BB, I realize that there have been studies made such as a couple you have referenced

hoosier: After I referenced them, I see you've changed your statement about there being studies conducted.

I understand that it's not conclusive yet whether it is definately a dangerous carcinogen or not,

from Wikipedia:

The United States Environmental Protection Agency first considered a ban on DDVP in 1981. Since then it has been close to being banned on several occasions, but continues to be available; concerns are primarily over acute and chronic toxicity, as there is no conclusive evidence of carcinogenicity to date.

http://en.wikipedia.org/wiki/Dichlorvos

But why even consider using something that's potentially harmful when you don't need to?

Using the 5 steps I outlined, you can almost certainly have a bug-free room without the need for such chemicals.


I say use chemicals as a very last resort, and definately not as a lazy "preventative" method.


Peace

 

[kalikush]

Its great to know that these will work if needed, but wont be needed this time..

I did read a of a study on another thread that said they fed this chemical to rats for 2 years, the rats did get cancer from eating this stuff for so long... Thats a long time to live tho with poison being one of your food groups. I might have to try these out since hoosierdaddy said they were safe to eat!

On another note, I had to chop down my gals last night. I will be focusing my attention to other areas of my life for now and do not have the time needed to keep these beauties anymore. Here are her final shots..

Actually this is NOT true. No offense to you Maj, I just have an unimaginable amount of animosity and well, just good all fashioned HATE built up from dealing with spider mites over the course of the past 2 years.
So I need to correct people when I see mistakes on this subject.

Female spider mites can live up to a month in hibernation ( In the soil, in your plant stocks, in the walls, carpet etc....

They come out instinctively when you switch your lights on to 12/12 and lay their eggs. So honestly, your only option is to either move from your current location or find a way to live with them. I.E. keeping them in "check"

As far as "you should only need one No Pest Strip" is complete rubbish.
I have had 2 in my flower room now for 8 days and not only did they not kill anything, but it seems as though it sped the little fuck bags up. I went in there today just to see complete destruction to my fan leaves. They are running around like they don't have a care in the world.
So I took out my last 2 (4 total now) and just surrounded my plants with them. We shall see what happens.
And yes the room is sealed, and no their is no fans or any time of ventilation of any kind.


You said in your area they are bad, you must be where I am, North Cali?

I jsut learned this, so I thought I would share it with you... it is not an easy pill to swallow.
The guy at the grow store told me that the mites from the humbolt/ trinity area are IMMUNE to just about everything.
This explains a lot, like how I spent over 400$ on pythrum bombs and azatrol with no effects.

soooo..... good luck?

Try predatory mites, let me know how they work.

I believe that's part of your problem

 

[supermanlives]

they work great for me

 

[CaptainTrips]

I believe that's part of your problem

I don't think so with no pest strips, you don't want ventilation because you'll just vent the active chemical out of your room and it won't do any good. It is possible I guess his mites are immume, my bro has lots of spider mite problems living up north in a "woody" area...
