Short answer: On most Ghanaian poultry farms the rats arrive first, and they come for the feed. Store feed in sealed bins off the floor, close every gap wide enough for a rat, and keep spilt feed and food waste out of the house. Snakes come for the rats, the eggs and the cover around the house, so a clean, tidy farm is the first snake control, and a trained handler is the right answer for any snake you cannot identify.
Key takeaways
- A rat in the feed store wastes far more than it eats. It fouls what it walks over, and fouled feed goes in the bin.
- Rats get through gaps about the width of a thumb. Check the wall joints, the floor edges and the pipe holes every month.
- Clear the edges of the house. Grass, rubble, sacks and timber give rats and snakes somewhere to live.
- Traps and bait stations belong in locked or protected places, away from birds, children and dogs.
- Do not handle a snake you cannot identify. Keep your distance and call someone trained to deal with it.
The rat in the feed store
The first rat we hear about is almost always in the feed store. A farmer opens a bin and finds the mash pushed to one side, a fine dust of droppings on top and a hole chewed through the corner of a bag. The rat is not hungry in any dramatic sense. It has found the best food on the farm, and it will keep coming back for it.
The feed loss is the obvious cost, but it is not the worst one. A rat walks through the mash, leaves droppings and urine, and drags whatever it finds across the bags. Some of that feed will be eaten by birds before anyone notices, and some will be thrown out. You have paid for the feed, lost part of it, and then have to clear up the mess too.
A farm with no rats in the store is a farm that has done the boring work. That work is not glamorous. It is sealed bins, raised pallets, swept floors and gaps that stay closed. It is also the same work that keeps the feed fresh, which is why the two subjects overlap so much in practice. Our article on storing feed and avoiding mould covers the other half of the problem.
Why rodents matter beyond the feed bill
Rodents carry germs. Rats and mice can pass salmonella and other bacteria in their droppings and urine, and they can carry parasites that move into a flock. A rat that runs across the feed, the drinkers and the nests puts those germs where the birds eat and drink. A house with rats is a house with a biosecurity problem, whatever the farmer intended. Our biosecurity article sets out the wider routine.
Rats also hurt the flock directly. They take eggs from nests, bite at the chicks' feet and combs, and a large rat in a crowded brooder can injure or kill young birds. Some farmers hear scratching at night and assume the rats are only in the feed. Those rats are often in the corners of the house as well.
Finally, rodents are a sign. A rat that has settled in your store means there is a way in, a food source and a hiding place. Find all three, and the rats will move on. Miss any one of them, and the population will rebuild from the next litter.
Finding the signs before the rat finds you
Rodent control starts with knowing where the rodents are. Walk the store and the house every week with a torch, and look at the places rodents use. Fresh signs matter more than old ones, so mark a droppings patch and check it again the following week.
| Sign | What it usually means | Where to check |
|---|---|---|
| Droppings along walls and under shelves | Rats moving on a regular route | Along the base of each wall and behind bins |
| Gnawed bag corners and torn sacks | Feed is the target, and access is already possible | Stacks nearest the wall and any bag with a weak seam |
| Grease marks on walls and pipes | Rats rub along the same line each night | Pipes, cable runs and door frames |
| Holes at the foundation or the floor edge | A burrow or an entry point | Outside corners, drain outlets and the base of the store |
| Broken or missing eggs in nests | Rats or snakes working the nest boxes | Nest boxes, low gaps under the nests, and the feed side |
| Chicks missing or wounded at night | Rats or a snake in the brooder | Brooder edges, the heat source and any gap at floor level |
Droppings are the most reliable clue. Rat droppings are larger and blunter than mouse droppings, and fresh ones are dark and moist. Dry, old droppings tell you the rodents were there last month, not that they are there now. Note the date you found them, and move quickly if the signs are fresh. Our nest box guide explains how to set the boxes so eggs are harder to reach.
Sealing the house: most of the work is gaps
Most rodent problems on farms are gap problems. A rat can squeeze through a hole about the width of a thumb, and it can gnaw through soft wood, plastic pipe and thin sheeting to make the hole bigger. The work is slow and unglamorous, and it pays back every month.
- Walk the outside of the house and the store with a torch, and mark every gap at the base of the wall, around pipes and where cables enter.
- Fill small gaps with mortar or a sealant that rats cannot chew through. Use metal mesh with holes no larger than about a centimetre where you need airflow, and finer mesh where mice are a problem.
- Line the bottom of a wooden door with metal sheet at the height rats can reach, so they cannot gnaw through the timber.
- Fit a metal cover over drain outlets and vent pipes, and check that the cover has not been pushed aside.
- Keep the gap under each door as small as the door allows, and check the threshold every month for daylight at the edge.
Do this before you spend money on traps. A house full of gaps will fill with rodents again within weeks, however many traps you set. The layout of the house matters here too, which is why our housing designs article covers the foundations and floor edges.
The feed store: the rules that stop most losses
The store decides how many rodents you carry. If feed sits on the floor, against the wall and in open heaps, you are feeding the rats every day. A few simple rules change that, and none of them needs a large budget.
- Keep every bag on pallets or raised boards, and stand the stack a short way clear of the wall so a rat cannot run from the wall along the pallet edge into the stack.
- Store feed in bins with lids that close fully. A lid that rests loosely on the bin is an invitation.
- Sweep up spilt feed every day, and do not leave scoops, bags or sacks lying on the floor overnight.
- Keep food waste, dead birds and kitchen scraps out of the store and away from the house. A rat that finds a bin of scraps stays near it.
- Rotate stock so old bags do not sit at the back for months. Old bags are the ones rats chew first, because they have been there longest.
The feeders themselves can help or hurt. A feeder that spills mash on the floor feeds the rats as well as the birds. Our article on choosing feeders and drinkers looks at designs that waste less.
Traps and bait: what works and where it goes
Traps work well when they are in the right place. Set snap traps flat against the wall, where the rats run, with the trigger facing into the run. A trap in the middle of the floor catches nothing. Bait with something the rat wants, and change the bait when it goes stale or dirty. Check the traps every morning, and empty them the same day so the rest of the house does not learn to avoid them.
Bait stations are useful where traps cannot go, but they need care. Rodent poisons are dangerous to birds, dogs, children and people, and a rodent that dies in an open place can be eaten by a bird or a dog. Use only products approved for use on poultry premises, keep them in locked, clearly labelled stations, and follow the label and the advice of a trained pest control adviser. We do not give product names or doses here, because the right choice depends on your site and on local rules.
Dispose of dead rodents with gloves, sealed in a bag, and put them in a bin away from the house. Wash your hands afterwards, and clean any surface they touched with a disinfectant you already use on the farm.
Snakes: what draws them in
Snakes come for the same things as rats, which is the first clue to controlling them. A rat population is a food supply. Eggs in an open nest are food. Thick grass, stacked sacks, timber piles, rubble and water pools near the house are shelter. A snake that finds all of those in one place will stay.
Many snakes in Ghana are harmless and eat rodents. Some are venomous, and the difference is not always easy to see from a distance. Treat every snake you cannot identify as dangerous. Do not try to catch it, kill it with a stick or chase it into a corner. Keep people and children away, and call someone trained to handle snakes, such as a local wildlife office or a snake handler who works in your area.
If you see a snake in the house, look for the reason it came in. Check for rats, look for eggs in the nest boxes and inspect the gap under the door. The snake is rarely the cause. It is the sign that something else is feeding it.

Clearing the edges where snakes and rats wait
The space around the house is where most of the rodent and snake problem starts. Keep the grass cut short for a band of a metre or more around the walls, and clear the rubble, bricks, old tyres and timber that build up against the house. Do not stack sacks or pallets against the outside wall, because that gives rats a ladder and snakes a hiding place.
A band of gravel or stone around the base of the house is worth considering. It is harder for rodents to dig under, anything moving across it is easier to see, and it drains better than bare earth. Keep drains and water containers clear, and empty any tray or bucket that holds water in the dry season as well as the wet.
Cutting back cover does not mean stripping the land bare. Birds need shade, and free-range birds need somewhere to hide from hawks. The aim is to remove the cover next to the house, not across the whole site, and to keep the path between the house and the run clear enough that you can see what is moving.
A worked example: one night in the brooder
Take a brooder with 50 Sasso chicks bought at 13 GH₵ each. The chicks alone are worth 650 GH₵. A gap at the base of the brooder wall lets a rat in one night, and the rat takes three chicks before the farmer finds the mess in the morning. That is 39 GH₵ of chicks in one night, before the feed, the heat and the labour already put into them.
Add a second night, when the trap was set in the wrong place and the rat comes back, and the total grows. The farmer then finds the feed in that corner has been fouled, and the bag has to go. The fix is a strip of metal sheet at the base of the brooder wall, a trap set against the wall and a sealed feed bin. The materials cost very little, and the whole job takes an afternoon.
This is why the gap check sits at the start of our brooder setup advice. A brooder sealed on the first day is far harder for rats to break into later, and you can then concentrate on the heat and the water. Our day-old chicks arrive in ventilated boxes ready for that setup.
A monthly routine that keeps both at bay
Rodent and snake control is a habit, not a single campaign. A monthly walk-round takes less than an hour, and it catches the gaps before the rats find them. Keep a simple record of what you find, what you fixed and when, so you can see whether the problem is shrinking or moving.
- Walk the perimeter and check the base of every wall for new holes, droppings and grease marks.
- Check each door threshold for daylight, and each vent and pipe entry for damage.
- Look inside every feed bin for chewed lids, droppings and moisture.
- Inspect the nest boxes and the brooder for broken eggs, chewed litter and wounded birds.
- Clear the grass, rubble and water containers at the edges of the house.
- Check the traps and stations, empty them, and rebait or remove them as needed.
- Write the date, the location and the action in the farm record.
If the signs keep returning after a month of sealing, feeding discipline and trapping, ask a pest control adviser to look at the site. A fresh pair of eyes often finds the route the farm team has walked past for years. Our farming calendar puts this monthly walk on the same wall as the feed and chick dates.
Questions farmers ask
Can a cat keep rats away from the farm?
A good cat catches the odd rat, but it will not keep a store clean. Cats do not stop rats getting into feed bins, and a rat population can grow faster than a single cat can handle. Treat a cat as a bonus, not as the plan. Sealing the house, removing food and setting traps in the right place do most of the work, and they keep working when the cat is asleep.
Are rat poisons safe to use near chickens?
Only if they are used exactly as the label directs, kept in locked, labelled stations, and placed where birds and dogs cannot reach them. Rodents that eat poison can die in an open place, and birds or dogs that eat the dead rodent can be affected. If you are unsure which product suits a poultry farm, ask a trained pest control adviser before you buy.
How do I dispose of a dead rat safely?
Wear gloves, or pick it up with a shovel and put it in a strong bag. Seal the bag, put it in a bin away from the house and wash your hands afterwards. Clean the surface it was on with a disinfectant you already use on the farm. Do not leave dead rodents in the open, where a bird, a dog or a child can reach them.
Does a snake in the house mean my farm is dirty?
Not always. Snakes come to rats, eggs and cover, and a clean farm can still have a snake pass through. A snake that stays is a sign that something is feeding it, so look for rats, nests and hiding places. Clear the edges, seal the gaps and check the nest boxes. Then the snakes have less reason to come back.
How can I tell a venomous snake from a harmless one?
You cannot reliably tell from a distance, and people get it wrong when they are close. Treat every snake you cannot identify as dangerous. Keep your distance, keep children and dogs away, and call a trained snake handler or your local wildlife office. Never try to kill a snake with a stick or a machete in the dark.
Should I kill every snake I see on the farm?
No. Many snakes eat rats and other pests, and killing one you have not identified can put you at risk. Where a snake is in a place it can harm birds or people, call for help and let a trained person move it. Your job is to remove what draws the snake in, so it has no reason to stay.
How often should I check traps and bait stations?
Check snap traps every morning, and empty them the same day. Check bait stations at least once a week, or as the label directs, and refill or remove them. A trap left set and empty for weeks teaches the rats to avoid it, and a station left unchecked can hide dead rodents where birds can reach them.
