I am just getting my fly spray system tuned up and ready to fire up as the flys are pretty heavy already. I am changing my suction filter and there is a ton of crap sitting on the bottom. I am wondering what to do with it? This is about 5 years worth of dust/hay/bugs along with the last little bit of fly killing juice that does not get sucked up when they systems low level shut off kicks in. it is probably 1-5 gallons of fly spray along with a sludge, I have no clue what to do with it, any ideas?
Shop vac, sister. I’d throw in a respirator while doing that job.

Not an issue getting it out, just dont know what to do with it when I do…
Pour it on your driveway and dilute it with the hose. Nowhere you want plants to grow.
Your local dump should take hazardous liquid waste. Bottle it up and take it there.
PLEASE don’t just dump it on the ground. Pyrethrin/permethrin is super toxic to water creatures, and that’s where it’ll go 
Where do you think it goes when it’s being run through the misting system? Into space?
Does the misting system dump five gallons at a time on the drive?
This is like saying “welp, I’ve got a little oil leak, so it’s okay to pour all my waste oil on the ground.”
It’s not.
1/5 gallons, and that includes a good amount of dust that has accumulated (the sludge)
Putting it on the drive and diluting it, as it’s water soluble, is not out of the question. 55 gallons (minus the 1-5 we’re speaking of) of the stuff is already sprayed on the ground.
Oil is not water soluble.
edit: I guess the OP could dilute it first, and then put it on the ground or spray their barn with it. Maybe a pump sprayer.
Potato-potahto. The stuff is ending up on the ground regardless.
Dude, I get that you’re pretty much “fuck the environment” but this is pretty egregious. Waste pyrethrin/permethrin should not just be dumped.
And https://www.epa.gov/safepestcontrol/safe-disposal-pesticides
“Check with your local solid waste management authority, environmental agency or health department to find out whether your community has a household hazardous waste collection program or a similar program for getting rid of unwanted, leftover pesticides.”
“Never pour pesticides down the sink, toilet, sewer, or street drain.
*Many municipal drinking water and wastewater treatment systems are not equipped to remove all pesticides.
*If pesticides reach waterways, they can harm fish, plants, and other living things.”
Again, where do you think this stuff is ending up when it’s going through the misting system? Outer space?
A gallon diluted and poured onto a porous gravel driveway is not egregious.
The amount of this shit that we, as horse people, spray all over everything - and then now we’re going to be environmentally conscious for the last gallon in a 55 gallon drum? Spare me the pearl clutching.

Oh, color me corrected - no need to dilute:
“If permethrin gets into the soil, it is broken down by microorganisms. Sunlight may also break down permethrin on the soil surface and on the surface of water.”
“Since permethrin sticks to sediment and does not mix well with water, it won’t usually contaminate groundwater.”
There’s a big difference between a few ounces sprayed onto barn surfaces and bedding, and 1 to 5 gallons dumped directly onto the ground. Despite what you claim, an interior barn spray system isn’t spraying directly onto the ground, or dumping 1 to 5 gallons at a time.
The direction from the EPA and others is clear: hazardous waste disposal is the way to go. It’s not hard. It’s likely something you’re already paying for with your taxes.
And lol yes, sure, a pesticide positive website is going to have a different recommendation, and alllllll those concerns about groundwater from organizations like the EPA are just so silly 
The EPA doesn’t consider 1-5 gallons of diluted product to be a reportable concern…
But ok. Bring it in if you want. Diluting it and putting it on the ground is like… exactly what the spray system does.
From the bottom of the page… but ok.
NPIC provides objective, science-based information about pesticides and pesticide-related topics to enable people to make informed decisions. NPIC is a cooperative agreement between Oregon State University and the U.S. Environmental Protection Agency (cooperative agreement #X8-83947901).
Do you not understand that these spray systems are installed inside barns? They’re not spraying on the ground.
I notice you left out some significant concerns from your copy/paste:
When permethrin gets into surface water like lakes or streams, it sticks very strongly to sediment and can stay there for more than a year.
Permethrin is highly toxic to fish and other animals that live in either salt water or fresh water.
Permethrin is highly toxic to bees and other beneficial insects.
@house it’s clear in your question that you’re concerned about proper disposal. Google around for your city’s hazardous waste disposal locations/dates, and they’ll be able to take it. 
I just want to be clear here - the stuff in the 55 gallon drum is ALREADY DILUTED down past the reportable limits. This is NOT the concentrate, as simkie wants to claim.
If you dilute it further, there is 100% absolutely no harm.
But if you want to put it in a jug and bring it in, by all means, bring your <1% permethrin in.
Oh, ok. So the bedding it contacts goes into outer space, then. And there’s no drift. Got it!
Again, spare me the pearl clutching…
EDIT: Look at the % AI on the SDSs you’re cut and pasting. All are 10% or better. This stuff is diluted WELL past that.
Please. I’ve made zero claims as to the strength of the waste here.
And see above about highly toxic.
If house wanted to or was comfortable dumping this onto the ground, there wouldn’t be a question here. There are ways to dispose of 1-5 gallons of waste that don’t risk waterways.
Spare me the casual pollution
You’re posting snippets of SDSs for concentrations WAY higher than what OP is dealing with here.
Find me an SDS with permethrin <1% with a reportable spill limit and I’ll eat my words. Link it.
The EPA link above that recommends hazardous waste disposal makes no qualifiers on “it’s okay to pour anything less than -x- on the ground.”
This also states no concentration.
So no. Nothing I’ve screenshot or linked qualifies hazardous waste disposal on concentration at all.
Of course there are risks to the environment dumping it. You think those are negligible. Someone who doesn’t can dispose of it with their municipality as hazardous waste. I’m sorry that bothers you.
