Rats burrowing into compost bin

    A month ago I got a compost bin for my organic waste which I have sitting on a raised bed. In retrospect the surrounding area was not very level. Last week I noticed that there were some burrow-holes leading into the bin from both sides. Then during the week I actually saw a rat from my kitchen window.

    Today I went to the garden centre and got a bag of top soil which I used to fill in the holes and pack down the surrounding area on all sides of the bin. Literally an hour later I spotted not 1 but 2 rats back at the bin. They immediately began trying to burrow down through the new soil and without too much difficulty one of them managed to gain access via the gate mechanism at the front which they inadvertently managed to knock out of place.

    I went out and replaced that back in position but 20 minutes later they were back again and started burrowing from both sides. I have no doubt that they well have a new entrance hole into it soon enough.

    What are my options here? I would prefer not to poison them.

    As for attracting them in the first place. I haven't put any cooked food, meat or fish in there. I did however put some broken up egg-shells in there so I'll stop that now. I saw one of them emerge with a piece of carrot so it looks like they're happy to eat the organic waste.

    We got a couple of cats which solved the rat problem nicely.

    Lots of heavy rocks or bricks around the base (making sure there are no gaps through which they could burrow) would help, as, I suppose, would a skirt of metal mesh that would go flat around the base and then up the sides of the bin (a bit like those fox-proof chicken enclosures), secured in place by something heavy (again, rocks or bricks). They may dig further away, but play it by ear. On the plus side, at least they're aerating your compost... :/

    Rats will burrow, chew and generally get through just about anything except decent concrete and metal. They also bring with them the danger of wiles disease - a danger in a garden especially if there are small children playing. I've seen rats chew the side of a wooden stable and the bottom of a heavy duty agricultural feed bin. If you dont wish to use bait - then use a live trap as it sounds like you have a breeding colony within reach. The eggshells are irrelevant and as you said they are eating the vegetable matter - they will quite happily come back for more of that. Here have a couple of farm cats that do the work of keeping rat numbers to a minimum. Good job they do to.

    Yea, but cats are vermin as well so what do you use to get rid of them?

    The most reliable solution is traps or poison. They say burying kitchen waste among the grass etc in the bin, helps deter them, as does keeping the pile sufficiently wet.

    I found some large rocks and have placed them around the outside edges of the bin. I'll keep monitoring it for the time being to see if they manage to find a way in.

    Unless they are flush, and all the nooks and crannies are coverd (and not by soil or gravel), they will.

    Luna rat traps and bait them with crunchy peanut butter. They are a timber trap with a picture of cats on.very good traps

    Seasoned composter here

    Best lines of approach:

    A. Fix a sheet of chickenwire across the underside of your compost bin, wire into position so it can't be moved. Rats are good at digging so earth will never be enough, and they can get around stones etc.

    B. Make sure that your composter doesn't contain food attractive to rats, eg, bread, cheese rinds or plate scrapings. Although these things can be composted, for now, don't put any of them in. No cooked food!

    C. Rats don't like change or disturbance, so, stir up the compost every day with a garden fork or something of the kind: hassle them daily. No rat mother will build her nest in a place that is constantly poked.

    D. Get a cat. Dog or fox will also catch rats.

    Get a board of wood, screw some rat traps to it, put peanut butter on the traps and sit back.

    Remove the food source, or use chicken wire. Attracting rats and then killing them is a bit, how one might say, a ****ty thing to do.

    Weldmesh is much better than chickenwire, but it needs to be narrow gauge.

    Take the food source away and they will be in the house next eating everything and sh1tting everywhere. They are vermin. They are not endangered or rare or anything. Just set a few traps and they are no longer a problem.

    But you have to keep setting traps, because the supply of rats is infinite.

    Cats don't necessarily go for rats, as they put up too big of a fight. I have two who will murder anything up to rabbit size but don't fcuk with rats.
    I don't put cooked food in my composter but the rats still attack it. My options are
    1. Get a "pig digestion composter" - They are very expensive.
    2. Build one with railway sleepers or even planks.
    3. Build one with conc. blocks.
    4. Essential to have the floor sealed with welded mesh, chicken wire is way too light to bother with.
    Plastic composters are essentially a waste of time and money.

    This one is pretty much set & forget (if a bit pricey)
    https://www.automatictraps.ie/

    plus it doesn't maim or poison, just kills quickly

    Interesting. I have an electric trap and it's caught nothing (and in any case would require emptying), but that one looks more developed.

    Ours most certainly kill rats including some quite big ones, not to mention the occasion magpie, and plenty of mice, pigeons and smaller songbirds, all of which end up back in the composter. Emptying the composter a couple of years ago my daughter grabbed a couple of skulls from said vermin to put on sticks in her cactus pots to give that authentic desert gulch look :)

    I'd avoid poison at all costs. The neighbouring shop laid some and I had a dying rat somehow manage to get under my floorboards. Even after taking out a kitchen unit and lifting most of the boards we never found the carcass and the stench was horrendous for over a month. The ensuing plague of bluebottles wasn't so great either.

    Not a big fan of house pets but have had some affection of cats since.

    With rats that have zoomed in on a particular food source you might have to change the bait. We were feeding birds (and by extension rats) all winter. They scorned the goodnature bait. As soon as we replaced it with birdseed we got results.

    Yeah, the problem with the zapper box I have is that the bait repository is a tiny vertical pocket which requires sticky bait, and that limits my options.

    Complete horse****. Rats look for filth, bins, compost heaps, dead animals, and somethwhere they'll be left alone and undisturbed. They don't try to get into houses unless it's a kip.

    Get rid of the compost, they'll head off, not try to get into a presumably clean and inhabited house.

    Or do the humane and easiest thing and bury some chicken wire. Just because they're not endangered doesnt mean its ok to attract them and then kill them. That's ridiculous.

    Not so.
    We have a reasonably clean house, no open food sources (other than birdfeeders during winter), a population of dogs and cats and still we've had rats overwintering in our attic for years.
    (despite no obvious way in that I can find or haven't blocked)

    I didn't want to kill mice in my shed so gutted it and they fled. A few months later I had them under the floorboards in the house and in the attic. Kill them now while you have the chance. Peanut butter really does work wonders I caught 10 in 2 days with one trap and peanut butter.
    The trap has sat their with peanut butter on it undisturbed ever since so it got the whole family. They couldn't help themselves.

    Rats love sunflower seeds, as I discovered a few years back - and like to make a nest with the seed hulls! Ingenious little feckers.

    I was once taking a leak and I seen a mouse on the window ledge of the upstairs bathroom. The windows w was frosted and he was scooting sideways across it like something out of a cartoon. We have pebbledash on the house I think they can climb it and get in the eves of the attic very easily.

    I had one, and I was very careful with what I put into it..a digger driver knocked it over one day, about 4 or 5 rats ran out of it...never got another one..
    Trap them is the most humane way..

    You can't generalise like that.
    I'm 48 years in this house, deeply rural, and have never had a rat in the house or a mouse. A few wood mice in the garage over the years but that's the lot.
    Composting all that time too and never a rat in the compost bins.

    Can I just clarify something. If I have a pile of grass clippings, leaves, small branches, thorny shrubs etc at the back of the garden and I turn it over with a fork regularly maybe mix in some soil to make compost, is this going to attract rats? Just all garden stuff and no food whatsoever?

    While rats will live outside for the summer they will seek shelter for the winter.Because last winter was mild there are larger numbers than normal around. Rats are a health hazard and should be treated as such.
    While some cats, and dogs will control them they are not always effective. They will attempts to live near a food source so along with feeding there they will nest and breed there. In reality you are generally never more than 10 feet from a rat.
    Poison is the most effective way if you are willing to use it. Use blocks as opposed to grain bait in a 3'' hollow tube. Attach the blocks to wire all blocks have holes to tie wire through. It is most effective if put down before rats move on. A rat when dying will return to where it came from to die. If rats die inside a house they were there before being poisoned.
    OP since you do not want to use poison traps are the only other choice. Even if you secure the compost bin rats will search for other food sources around your house, shed and garden. Rats usually enter houses or sheds through small openings so make sure there is none of them around.
