Is there some kind of gas like co2 that can kill insects?

The gas should have some kind of oil that can make dead bugs roll off the leaf and collect at the bottom of the plant, maybe something like neem but gas specific

...like pyrethrum bombs? total release foggers? Don't know about collecting at the bottom but if you want ot set off a couple of bug bombs, I'd put a paper plate underneath them to collect the bit of goo they spurt at the end.

Helium will kill mites without killing plants, supposedly 12hrs in a dry cleaning bag works. Hrmm... I have some small plants I just found mites on, I just might be able to test this soon. lol

CO2 would probably be the most beneficial to your plants while gassing any bugs.


What you are asking about with the oil in it sounds more like a pyrethrin bomb like bsgospel explained. It's an aerosol bomb. I think they're pressure source may be CO2 though. I don't have a bomb to look at and see.

I've gotta dig up the thread. The concensus was 100% CO2 is bad for the plant after a few hours, while helium didn't seem to bother them.

I used pure CO2 to kill fleas, and it's similar to killing spider mites.

The amount that will kill the spider mites is not good for the plants.

The old chemistry gas formula is helpful

PV = nRT

P ~ pressure
V ~ volume
n ~ number of moles of gas
R ~ gas constant
T ~ temperature in absolute terms.

& the units have to work out. I used 4 pounds of CO2 to gas a twin sized mattress.

Ethyl acetate? It's a volatile liquid and it likely goes BOOOM!!! when you switch on the lights... it's used by people collecting bugs and butterflies .
