The Most Common Bugs Found in the House

From tiny pests that nibble through your furniture to unwelcome guests hiding in your bedding, common household insects can be more than just a nuisance. Many types of house bugs not only invade your living space but also cause structural damage, contaminate food, and pose health risks. This guide explores some of the most common household bugs and how to identify them. We also give out tips for dealing with each type of house bug.

Whether you’re seeing ants in the kitchen, bed bug bites at night, or cockroaches in damp rooms, early identification and targeted treatment are key to stopping an infestation from spreading.

Types of House Bugs

Ants

Ants are among the most common bugs in the house, and while many species are harmless, some can become problematic. Pharaoh Ants, in particular, are notorious for their ability to infest homes. These tiny yellowish ants thrive in warm, humid environments and are known for contaminating food and spreading bacteria. Black garden ants, another common household insect, often invade kitchens in search of sugary treats. We can eradicate both types.

Ant infestations are likely to start outdoors and move inside through small cracks around doors, windows, or pipes. If this issue is left untreated, colonies can split up and make satellite nests in walls, under the floors, or even behind appliances.

Signs of an Ant Infestation:

Trails of ants leading to food sources.
Small piles of dirt near entry points or cracks in walls.
Tiny frass (droppings) near skirting boards or worktops.

Prevention Tips:

Keep food stored in airtight containers
Seal cracks and crevices where ants could enter
Wipe down surfaces to get rid of all sugary residues
Fix leaking taps to reduce moisture.

Treatment options include gel baits, residual sprays, and professional ant control services for persistent Pharaoh ant colonies.

Bed Bugs

Bed Bugs are small red or brown-coloured insects that feed on human blood at night. These elusive pests hide in mattresses, bed frames, and even cracks in walls, making them difficult to spot until their bites appear. This common household insect often requires professional pest control. At Total Pest Control, we offer Bed Bug Heat Treatment services that do just that.

Bed bug infestations can spread quickly through bedrooms, sofas, and luggage. Bites often appear in lines or clusters and might cause itching, allergic reactions, and poor sleep.

Signs of a Bed Bug Infestation:

Itchy, red bites on the skin often appear in lines or clusters.
Bloodstains or dark spots (these are faecal matter) found on bedding or mattresses.
Shed skins, egg shells, or a sweet, musty odour in severe cases.

Prevention Tips:

Regularly inspect and vacuum mattresses and furniture.
Wash bedding at high temperatures.
Check second‑hand furniture carefully and avoid placing luggage on beds when travelling.

Professional heat treatment raises room temperatures to levels that kill bed bugs and their eggs in a single visit, offering a chemical‑free solution for homes and HMOs.

Cockroaches

Cockroaches are hardy insects that can quickly become a major household pest. Common species like the German cockroach or American cockroach can contaminate food and spread diseases. This type of house bug is particularly drawn to warm, damp environments such as kitchens and bathrooms. Read below for signs of an infestation and how to deal with them.

Cockroach droppings and shed skins can trigger allergies and asthma, especially in children. Infestations often centre around appliances, drains, and cupboards where food and moisture are available.

Signs of a Cockroach Infestation:

Foul odour caused by their droppings
Shed skin or egg cases near hiding spots
Smear marks on walls
live cockroaches seen at night.

Prevention Tips:

Keep surfaces clean and free of crumbs
Address leaks to remove moisture sources
Store pet food in sealed containers and take rubbish out regularly.

Treatment to combat cockroaches might combine gel baits, insect growth regulators, or targeted sprays to break the breeding cycle and prevent reinfestation, but sometimes professional cockroach pest control is needed.

Fleas

Fleas are a common household insect for pet owners, but they can also infest homes without animals, thriving in carpets, soft furnishings, and cracks in flooring. These tiny, wingless insects are highly mobile, jumping from one host to another or settling into upholstery and rugs, where they lay eggs and multiply. Their bites can irritate humans and pets.

Read our blog on 7 Signs of Fleas in the House & How to Avoid an Infestation for more information.

Flea life cycles can continue indoors for months, with eggs and larvae hidden deep in carpets and under furniture. Untreated infestations often lead to repeated bites and ongoing pet discomfort.

Signs of a Flea Infestation:

Frequent scratching in pets
Small red bites on your ankles or legs
Flea dirt (black specks) on pet bedding or carpets that turn red when wet.

Prevention Tips:

Regularly treat pets with flea prevention products
Vacuum carpets and soft furnishings regularly
Wash pets’ bedding on a hot cycle
Be sure to treat the whole home, not just one room.

Professional flea control combines residual sprays for floors and skirting boards with advice on treating pets and laundering textiles to stop re‑infestation.

Pharaoh Ants

As previously mentioned, Pharaoh Ants are particularly troublesome due to their resilience and ability to form multiple colonies. These tiny insects are common household pests, often spreading bacteria and other pathogens. Although home remedies can sometimes work, it is best to get professional pest control services to eradicate them and prevent them from returning.

Pharaoh ants are frequently found in kitchens, bathrooms, and utility rooms where warmth and moisture are high. They are known to nest in hard-to-access areas of the home, such as behind tiles, under baths, and inside wall cavities. This means DIY treatments aren’t always guaranteed to work.

Signs of a Pharaoh Ant Infestation:

Tiny yellowish ants that tend to move in lines
Most likely found in warm or moist areas, like kitchens and bathrooms
Multiple trails are found during different times of day.

Prevention Tips:

Keep food sealed and stored.
Seek professional pest control for effective treatment.
Repair leaking pipes and improve ventilation to reduce humidity.

With professional ant pest control services, specialist baiting programmes are usually required to target the main colony and satellite nests without causing the colony to split.

Silverfish

Silverfish are small, silver-coloured insects which vaguely resemble a fish. These nocturnal bugs thrive in damp, dark areas like bathrooms, basements, and kitchens. They feed on starchy materials such as paper, glue, and fabrics, potentially damaging books and clothing. Although not the most common type of house bug, their presence can be particularly impactful.

Silverfish damage is often seen as irregular feeding marks on wallpaper, book bindings, and natural fibres. High humidity and poor ventilation make properties more vulnerable to ongoing infestations.

Signs of a Silverfish Infestation:

Small holes in paper products or fabrics.
Yellowish stains on stored items.
Shed skins in cupboards, lofts, and under sinks.

Prevention Tips:

Reduce humidity in your home with dehumidifiers.
Store items like books and clothing in sealed containers.
Improve airflow in basements and lofts and fix any damp issues.

Targeted residual treatments in voids, skirting boards, and storage areas can help control silverfish alongside environmental improvements, but some infestations will require professional silverfish pest control.

Woodworm

Woodworm refers to the larvae of wood-boring beetles that burrow into and feed on timber, damaging wooden furniture, beams, and floors. Their activity leaves small holes and powdery frass, and, over time, can weaken the structural integrity of your home, leading to costly repairs if untreated. Read below to learn how to identify this common bug found in the house.

Woodworm attack is most common in older properties with untreated softwood beams, floor joists, and furniture. Severe infestations can compromise structural timbers if left for several years.

Signs of a Woodworm Infestation:

Tiny holes in wooden surfaces
Fine powder (frass) near infested wood
Weak or crumbling timber that breaks easily under pressure.

Prevention Tips:

Treat wooden items with appropriate preservatives.
Inspect furniture and beams for signs of infestation.
Maintain low moisture levels in lofts and under floors.

Professional woodworm treatment uses micro‑injection and surface sprays to penetrate timbers and stop larvae development; this is sometimes combined with a structural survey in severe cases.
