Managing flys and manure. Seeking advice.

I have a fly problem and with all the bunny poop that had been accumulating. It got wet because of a water leak from their water feeder that has been fixed. Now I have this problem with what appears to be fruit flys. The neighbor is complaining and has not said anything to management yet.

Long story short is marjorty of the bunny poop, hay,  urine, and water fall into a 100 gallon tote. This is for easy cleanup with a shovel. The structure that suspends my rabbit cages is made out of wood is propped up on PT 4x4 blocks that can be thrown away over time if they rot too much, they are free. Everything rests on a concrete slab.

I have a fly problem, but basically I have a manure problem. I don’t thing this the best way to manage my manure anymore. The worm bin is not too far away and can be put in with 1 or 2 stepsCurrently considering the following options

1. letting everything fall to the concrete then either vacuuming it up with a wet/dry shop vac then putting it a worm bin every day or every other day. I would buy this shop vac used on Craigslist.
2.  Letting it all fall to the concert and getting a push broom and shoveling it up  using a 4x4 as a back stop and putting that in the worm bin.
3. Collecting the manure and bagging it up.

Right now I am a fan of the vacuum idea. I could vacuum up flys too. Everything. Would be contained.

Can everyone else please give me your thoughts. Some pictures below. Let me k is if you need more information.

We find the poo isn't stinky at all, plus we use a litter box, which catches the pee.
We use a lot of dry hay to absorb the urine,  but we are thinking about switching to hardwood pellets.

I think maybe you should cover wet waste with dry material right in the container where it currently
collects, then add worms and compost in place.
As it fills, remove partly  composted material and top your   beds with it

Bunny poop is a 'cold manure', and can go directly to the garden beds. A once a week clean-out could go straight to wherever is most needed, in your garden. Hose down the urine waste, and you're good to go.

I just compost all of mine, bedding and all, clean a little more frequently, and use fly strips in the rabbit barn and we're good. We still get flies, but not as many when management is poor, six fly strips for about $5 covers us for the year usually.

I'm thinking that a redesign of your rabbit hutches might be in order.  The idea is to work smarter not harder.  

Elevate the bedding area and put some kind of a tray under it to catch anything that falls through.  A simple piece of sheet metal with some edges would be sufficient.  

Slope the catch try so that the liquid runs into a bucket for dumping onto the compost heap.  Think shower drain pan but maybe less of a slope.  

Some sort of a push or rake to dump the solids into the top of the worm bin.  A wooden 2x4 cut to length that can you push or pull to rake everything out

As for your current issue, if you dig some holes and bury that mess, the flies will vanish.  

Soap and hose are your friends.  

I have tried a few different things

First I got a wet/dry shop vac on Craigslist for about 80 bucks. Works ok but not great. Makes some noise but the rabbits tolerated it with the long hose. Hay got stuck where the hose meets the  top. Became to much of a problem and that idea got scraped.

Second went to Home Depot to get a leaf blower sucker the ide was to suck it all up.Made to much racket and had to take it back.

Third I tried a little dewalt blower. Found it on Craigslist for 90 bucks brand new with no battery. Already have 3 batteries for it.used it on all 3 speeds at 100% and bunnies did not freak out. I can use this in many of the places around my house as well

Your friend has shared a link to a Home Depot product they think you would be interested in seeing.
