DE works forever essentually...however rain and wind remove it
..wind obviously blows it away and rain causes it to seep into the soil-but its good for the soil.
In your home it will last a long time seeping through carpet to the pad and depending on how good you vacuum is it will last down there unforuntately fleas lay eggs near the surface and hop along the surface so DE needs to be on the surface and vacuuming removes it.
Having said that treating an indoor flea infestation with De you leave it on surface 24-48 hours repeat every week for 6 weeks to end the entire flea cycle. Personally we use it for dust mites as my son is allergic to them.
Mosquitos lay eggs in water water dillutes and counteracts DE, will iy kill an adult mosquito yes but don't put DE purposefully in the air of your home research on its ability to do lung scratching when inhailed is two sided-side with caution.
We use DE in a 'hand duster' on our roses to kill afids as well.
If you buy DE from Lowes etc in nice little prepackaged name brand bags you are paying for packaging.
Mine is $22-27 for a no name white bucket that's about 20 pounds, why the whole sale price varies by season the garden store couldn't tell me they just mark it up 30%for above cost.
PLEASE BE SURE YOU BUY ORGANIC FOOD GRADE DE!!!!
DE comes in 2 forms organic for garden use and chemical for purification (like used in industrial pool filters) chemical DE WILL KILL YOU. It is highly toxic topeople, pets plants and while used at your lical pool or hotel pool its used by the part per million in water...so don't go to the industrial supply place and get DE. |
