Pyrethrum TR fogger. (organic insecticide) Need help with follow up application.

I used a pyrethrum tr fogger 2 days ago and i have read that a follow up second fogger is usually needed. However, I need some input of how many days to wait before using the second fogger. Can anyone help?

3 days in most instances for most bug infestations. 3 bombs total for best results.
They sell 3 packs on ebay for pretty cheap. I think its like $52 USD.

Thanks for the reply. I have used one and also sprayed spinosad. I haven't found anything alive since then but I will use a second fogger. Do you really think I need a third fogger? My room is pretty small and the fogger is up to 3000 sq feet

Also i forgot to add the infestation i had was thrips

probably dont need the 3rd, but is a precautionary step. The first bomb kills off the adults. The second it to kill off the eggs that get dropped when the first bomb goes off and to make sure there are no adult survivors from the first bombing. Its to kill off the life cycle of the bug so a reinfestation doesnt happen and the bugs now have a tolerance against the pyrethrum used.

Ok i may get the 3rd fogger then. I appreciate the help.

Just an fyi-
Keep the fogger away from plants while fogging. The pyrethrum isnt toxic to the plants, but the propellant in the fogger is and will burn and kill foliage if it is too close. Its also flammable as hell so dont use any fans,timers,lights or anything that is electrical while fogging. Wait about an hour or 2 so before going back into the room and exhausting it. It will leave a film on everything in the room, including equipment so be sure to wash fan grilles, and photosensors, etc after bombing.

ok i have a cupboard in the corner of the room which i put it on last time and it seemed to keep the plants without any damage. I had to go back in the room after 1.5 hours to just turn on the dehumidifier because the humidity was already up to 90 and i am in flowering. Do you think that is fine? I covered lights and ac with plastic bags.

Thats fine. After that long your ok to turn on your lights,fans pumps, timers etc and resume as normal.

for sure thanks HydroRed, you were great help to me.

No problem, good luck.

I am in day 20 of flower and I want to use a pylon tr bomb..I've used them b4 but I am afraid it will burn the hairs. If I put it in a corner away from plants directly will I be okay??

At 20 days into flower, you still have quite a bit of time and growth to take place so chances are if you did prematurely turn hairs orange, you wouldnt even notice by the time harvest day arrives. Likely a small tradeoff depending on why you are bombing. You want to have the bomb going off indirectly from the plants anyways, so in a corner away from plants is ideal. I used mine approx. 36" away from the nearest plant but I understand not everyone has that much room to play with.

I have noticiable flower growth and not to mention o could baby thrips on my new cuttings..I cant find any on the adults but they are hard to spot sometimes so this would be mostly a precautionary measure

Spinosad works like gang busters on thrips and is far less aggressive of a remedy than Pyrethrum. You can use it like a foliar instead of a bomb.

Will the bombs harm my plants you think?

Cant say because there are so many factors involved (how big is your room, how close are the plants, how old are the plants, how healthy are the plants...etc). I've used Pyrethrum bombs before with great success but it was always a last option when other methods didnt work. I would seriously recommend just buying a bottle of Monterey brand insecticide with Spinosad. Spray it on the plants like a foliar 1 time and be done with it. Its virtually harmless to the plants when applied as directed.

I just found out about my infestation about 2 days ago. Today, while lights off I used Monterey Garden Spinosad. I sprayed the placed down. I'm planning on using a Pylon TR Fogger because I haven't had success with Pyretherin TR foggers. I want to use the Pylon Thursday same time as I spniosaded today. 3 days after that, I will probably run it down with some spinosad again. Attached some pictures for you to see, they're eating at my buds and making them look light green....
