Rat proof metal composter


Metal composters are made of sturdy metal grids, which are connected to each other on the long sides. The wire or grids are made of steel sheet. To protect against corrosion, the steel is hot-dip galvanized. This ensures a useful life of several years. Provided that the wire is not too thin, such composters are relatively rat-proof. However, you must take care that rodents cannot enter the composter from below or above.

Quick or thermal composters made of plastic


Although plastic is softer than metal and can be gnawed by rats, closed containers made of plastic are also rat-proof composters. The walls are thick and sturdy. They are not easily destroyed. The weak point of quick composters and thermal composters are the ventilation openings. If they are too large, rats or mice can get in through them. It can help to make them smaller by using wire mesh.

How To Rat Proof Your Compost Pile

When buying a rat-proof composter are some points to consider. To help you find the right rat-proof composter, we have summarized the most important buying criteria for you here.

Stability


To prevent the composter from tipping over or being moved by the rats, it should have good stability. So when buying, make sure that the composter is attached to solid ground anchors and/or has a sturdy frame.

Floor grid


If you want a rat-proof composter, be sure to choose a model with a bottom grid or order one as an accessory. A sturdy metal bottom grid or bottom plate will prevent rats from digging their way into the composter from below.

Mesh size


A rat-proof metal composter should have meshes no larger than 12 mm maximum. Mice and even rats can squeeze through larger meshes. Once the rat’s head fits through, the rest of its body will make it as well.

Material


Wood is unsuitable as a material for rat-proof composters. It can be gnawed through too easily. Metal, on the other hand, is ideal, provided it is thick enough. Plastic can also be used if it is thick enough. However, there is no one hundred percent certainty.

Cover


To make a closed composter rat-proof, the lid should have a latch and close tightly. For metal composters, be sure to order or build your own lid made of sturdy wire mesh or mesh panels.

Price


There are no exact guidelines for how much a rat-proof composter should cost. However, the better the workmanship of the device, the more expensive it will be, of course. In principle, however, a model from about 60 euros is worthwhile. Compare different offers and decide on the variant that best suits your needs!

Design


The rat-proof composter is available in different designs. So you can choose between a model with an open or closed bottom tray. There are also variants where the compost bin is surrounded by a plastic hood, which is designed to keep rats and other animals out. With this variant, however, care should be taken not to create gaps through which rats could gain access.
