How do I stop rats, foxes and flies getting into my bins?

Bins are the single most reliable food supply in a British garden, and almost every rat, fox and blowfly problem around a house traces back to them. The fix is not one thing but an arrangement: what goes in, how it is contained, where it stands and how often it is cleaned.

What you'll need

• Bins with lids that close fully
• A bin store or a hard standing area (optional)
• Bin lid locks or straps (optional)
• Hot water, detergent and a stiff brush
• Compostable caddy liners (optional)

Step by step

1. Start with the food waste caddy.It is the highest-value target in the whole arrangement and usually the least well sealed. A latching lid, a liner, and the caddy kept indoors between collections rather than beside the back door.
2. Wrap and freeze the worst of it.Meat, fish and bones frozen until collection day removes the smell entirely. It is the single most effective change for summer flies and for foxes.
3. Check every lid closes fully.An overfilled bin whose lid sits open is an open buffet. If the bin is regularly too full, that is a capacity conversation with the council rather than a reason to leave the lid up.
4. Never leave sacks on the ground.A bag beside a full bin is opened by a fox or a gull within hours, and the contents then feed rats for a week. If there is overflow, keep it inside until collection morning.
5. Stand the bins on hard ground, clear of the wall.Paving or a slab rather than grass or gravel, and 200mm or more from the wall so nothing can shelter behind. Rats want cover, and a bin against a fence in long grass provides exactly that.
6. Keep the bins away from the house and away from cover.Not against the back door, not tucked behind a shed, not next to a hedge. Open, visible and reachable — which also makes them easier to clean.
7. Wash the bins out, not just the bags.Residue under the rim and in the lid hinge is where kitchen flies breed. Hot water, detergent and a stiff brush every few weeks in summer, and let it dry with the lid open.
8. Build or buy a bin store with a solid base.It hides the bins, holds the lids down and stops foxes tipping them — but it must have a solid floor and no gap at the bottom, or it becomes a sheltered nesting space rather than a solution.
9. Deal with the recycling too.Rinsed containers, no residue in the base of a box, and a lidded container rather than an open crate wherever possible. Unrinsed tins and bottles are a substantial attractant.
10. Use lid locks only where the collection allows.Straps and locks help against foxes and gulls, but some collection crews will not empty a bin they cannot open. Check what your council accepts before buying anything.
11. Put the bins out on the morning, not the night before.A bin standing on the pavement overnight is available to everything. Morning presentation removes the whole night-time window.

Tips

• A handful of bicarbonate of soda in the bottom of the food caddy reduces smell noticeably without any chemistry that matters.
• If gulls are the problem, the bin bag on the pavement is the issue. A rigid bin or a gull-proof sack from the council is the fix.
• Do the bin clean on a warm morning and leave the lids open to dry in the sun — it does more than any disinfectant.

Common mistakes

• Keeping the food caddy outside the back door — It is warm, close to shelter and full of exactly what attracts rats, foxes and flies. Keeping it indoors between collections is the single change that solves the most.
• A bin store with an open bottom — It gives rats a dark, dry, sheltered space right beside the food source. A solid floor is what makes a bin store useful rather than harmful.
