Mites and lice rarely kill quickly. They take sleep, feed and eggs a little at a time, and most of the work happens between batches.

A slow thief in the layer house
A layer house can look perfectly fine from the door. The birds are scratching, the feeders are full and the water is clear. Then the egg count drops by a few a day, the combs look a little pale, and a handful of hens sit low on the perch with their feathers puffed out. Nothing dramatic has happened. Something small has been feeding on the flock for weeks.
Mites and lice are the usual suspects, and they seldom kill birds quickly. They take blood a little at a time, irritate the skin, and interrupt rest. A hen that cannot sleep properly does not put her energy into eggs, and a bird that is itchy all night eats less in the morning. That is why many keepers only notice the problem when the production line has already dipped.
Lice and mites are different enough that they need different handling, and this guide is about prevention and good husbandry first. Treatment choices belong with your vet, who knows your flock and the products registered in Ghana.
Two pests with two habits
The two are often lumped together, but they behave differently, and that difference decides where you look.
Feather lice live on the bird. They spend their whole life on the feathers, mostly around the vent, under the wings and across the breast. In daylight you can part the feathers and see them moving. They spread when birds touch each other, so a crowded house or a mixed flock lets them travel faster.
Red mites work on a different timetable. During the day they hide in the cracks of the house: perch joints, nest boxes, the gaps round old wood, the seams of battery cages and the corners where dust collects. After dark they come out, feed on the birds and return to their hiding places before light. A bird can be bitten badly while the keeper sleeps, and the mites are gone by the time anyone walks in.
That is why a daytime walk through the house often finds nothing, while a night check finds plenty. It is also why cleaning the structure matters more than working on the birds alone.
Where they hide in a Ghanaian house
Most houses have more hiding places than their owners realise. Old jute bags hung on a wall, split wooden perches, mud packed into a crack and never allowed to dry, and the underside of a feeder rail all make good shelter. Reused wooden crates as nest boxes are a common trouble spot, because the wood soaks up droppings and the cracks never quite close.
The outside matters too. Litter piled against the wall, feed bags left open by the door, and wild birds roosting on the roof all bring pests closer to the flock. Mites do not need a bird in the house to survive, but a bird is their route to a meal, and wild birds can carry them in.
A clean, dry house gives pests fewer cracks to hide in.
What the signs tell you
Pests leave clues before they cause real damage. The table below sets out what to look for, where to look, the likely cause and the first thing to do. It is a starting point for your own observation, not a diagnosis. If the signs persist or the egg count keeps falling, call your vet.

The night check that actually finds them
Go in after dark, when the house is quiet and most birds are on the perches. Walk slowly. Use a torch with a steady beam and hold it low, so you can see the perch and the boards beneath it. Work through the house in the same order every time, so nothing gets skipped.
Stop at the door and listen. A flock that is itchy sounds restless, with more shuffling and fewer birds settled.
Shine the torch along the perch edges and into the joints. Look for small reddish or grey specks that move or sit in the wood.
Lift a few birds gently, one at a time, and check the vent and the skin under the wing. You do not need to handle the whole flock each night. A handful of birds from different spots tells you whether the house has a problem.
Check the nest boxes, especially the corners and the lower edge where the wood meets the floor.
Write down what you saw: the date, the spot, what you found and roughly how restless the flock was. Keep it in the same book as your egg count, so the two can be compared.
Key takeaways
Lice live on the bird and can be seen in daylight. Red mites hide in the house by day and feed at night.
A night check with a torch finds red mites far more reliably than a daytime walk.
Clean, scrape and dry the house before new birds go in. Most of the pest population lives in the structure.
Treat with a product your vet recommends and the label allows, and never guess the strength.
Keep a short record so you can tell whether the problem is shrinking or just moving.
Cleaning between batches is where you win
Most of the pest work happens when the house is empty. Once the birds are on the floor, you are fighting a population that has already settled in, and every disturbance pushes the mites deeper into the cracks. Between batches you have time to reach every joint, and that time is the cheapest protection you will ever buy.
A workable order looks like this:
Remove all litter and droppings, and carry them well away from the house. Old litter piled next to the building is a breeding ground in its own right.
Take out the perches, nest boxes and any wooden fittings that are split or soaked. Scrape the cracks properly. Replace what you cannot clean, because wood that stays wet will keep the pests in business.
Wash the house from roof to floor with plenty of water and a poultry-safe cleaner. Pay attention to the corners, the underside of rails and the joins where two boards meet.
Use a disinfectant labelled for poultry houses. Follow the label for how strong to make it and how long it should stay on the surface. Do not guess the strength, because too weak does nothing and too strong can hurt the birds you bring back.
Let the house dry fully before new litter or new birds go in. A damp house is a welcome for mites.
The drying step is the one most people rush. In the rainy months a house can look dry on the surface and still be damp in the cracks. Wait longer than you think you need, and check the wood with your hand, not your eye.
Broiler houses have a different risk. Litter is the bedding, so the main job is to keep the litter dry and to remove any old litter from the last flock completely. Layer houses have the cages, perches and nest boxes, which is where the cracks are. Both need the same discipline between batches, applied to the places that suit each system.
Rainy season, harmattan and the house in between
Warm, humid weather favours red mites. They breed faster when the house stays warm and the cracks stay damp, which is why many keepers see more trouble in the wet months. The harmattan dries the air and the dust, and that can slow things down. It does not clean a house, though. Dry dust packed into the cracks is still a hiding place.
Dust baths help birds keep their feathers in shape, so give them a dry, clean area with fine sand or soil that stays loose. Keep the dust bath separate from the droppings area, so it does not turn into a patch of old manure.
Whatever the season, pests usually come in with three things: new birds, used equipment and old litter. This is why the arrival routine matters as much as the cleaning routine. Equipment that has been to another farm should be washed before it goes near your flock, and any birds you bring in should be held apart at first. Our guide on bringing new birds in safely covers that step in detail.
Treat with a plan, not a guess
Once you have found mites or lice, the temptation is to buy the first product the shop has and spray the flock. Resist that. Ask your vet which product suits your birds and your stage of production, and read the label before you open the bottle. Some products are meant for the house and some for the birds. Using them without advice can harm the birds, waste money and leave the pests unbothered.
Think about timing too. If birds are close to being sold for meat or eggs, the product label tells you how long to wait before the bird or its eggs go to market, and that wait is not optional. Our guide to the withdrawal period before slaughter explains how to plan around it.
Keep a simple record: the date, what you saw, what you did and when you did it. Over six weeks you will know whether the problem is shrinking or simply moving from one corner of the house to another. That record is also the first thing your vet will ask to see.
If you are short of money for a proper clean, do the parts that cost nothing first. Remove the old litter, scrape the cracks, wash with water and let the house dry. Those steps alone cut down what the pests can hide in, and they make any product you buy later work better.
What ignoring them really costs
A pest problem costs more than the product on the shelf. The birds eat the same feed while producing less, and feed is more than half of what you spend on a flock. A 50 kg bag of feed runs broadly from GH₵400 to GH₵470 depending on brand and season, so every week of lost laying is a week of feed bought for fewer eggs. Confirm the current price of your brand locally, because it moves.
Restless birds also bruise and feather-pick, and a flock that is always scratching cannot settle. Keep the house and the birds in good order, and most of these costs never arrive.
Can I see red mites in the daytime?
Sometimes, but they mostly hide in cracks and joints during the day and come out to feed at night. A torch and a night check are far more reliable. Feather lice are the exception, because they live on the bird and can be found in daylight by parting the feathers around the vent.
Do mites and lice make birds sick on their own?
They can do real harm slowly, through blood loss, irritation and broken rest. They can also weaken a bird so that other problems take hold. If egg output or condition drops, have your vet check the flock and rule out other causes, rather than assuming pests are the whole story.
Should I treat the birds or the house first?
Clean and dry the house first, because most of the population lives there. Treat the birds afterwards, using a product your vet recommends and the label allows. Working on the birds alone while the house stays dirty usually means doing the job twice.
Can a new batch bring mites into an old house?
It can, if the house still holds old pests. Our chicks come from a clean hatchery, but any house with a pest history needs cleaning and drying before the birds arrive. Ask us about the batch you are ordering, and confirm the current price and hatch date before paying.
Start the next batch clean
When the house is cleaned, dried and ready, the next step is a healthy flock to fill it. Send the order form on the site or call 024 915 1503. An order starts with a message, not with money. Before you pay, we confirm the price, the hatch date and the delivery cost, so nothing surprises you when the box arrives.

A weekly weighing routine for broiler farmers: how to pick an honest sample, the weights to compare against from day 7 to day 42, the average and uniformity sums, and what to do when the flock is behind.
Feed cost per kilo of broiler depends on how much feed each kilo takes and what you pay for it. These ten habits lower both without starving the birds or buying additives.
Heat kills the heaviest broilers in the last days before sale. This guide explains why, shows the signs in order, and sets out the house, stocking, water and feeding changes that prevent it, plus an afternoon emergency plan.
