Common Household Pests in the UK and How to Identify Them

HomeLifestyleCommon Household Pests in the UK and How to Identify Them

Household pests can be a significant nuisance, causing damage to your property and potentially impacting your health. In the UK, several common pests can invade homes, and it’s crucial to identify them correctly to take appropriate action. This article will guide you through identifying and dealing with common household pests you might spot in your home or business.


Mice and rats are among the most common household pests. House mice are small, typically around 7-10 cm long, with large ears and a pointed nose. Signs of a mouse infestation include droppings, gnaw marks, and a musky odour. Rats, on the other hand, are larger, measuring 16-40 cm long, with a blunt nose and smaller ears relative to their body size. Rat infestations are characterised by larger droppings, gnaw marks, and burrows. Advance Pest Control Bristol can help if you’ve noticed any of these signs.


Various insects can infest our homes, causing discomfort and potential health risks.

  • Black garden ants and pharaoh ants are common species, ranging from 3-5 mm in length. Ants are typically found in kitchens and bathrooms, attracted to sugary substances and moisture.
  • Bed bugs, small, oval-shaped insects around 4-5 mm long, feed on human blood and can cause itchy, red bites. Signs of a bed bug infestation include dark spots on mattresses and a sweet, musty odour.
  • Cockroaches, such as the German and Oriental species, are another common insect pest. German cockroaches are light brown and around 10-15 mm long, while Oriental cockroaches are darker and larger, measuring 20-30 mm. Both species prefer warm, humid environments and can spread bacteria and trigger allergies.
  • Fleas, small, wingless insects around 2-3 mm long, can infest homes through pets. Signs of a flea infestation include excessive scratching in pets and small, dark specks in their fur. Fleas are notoriously hard to get rid of and often require professional pest control in Bristol.

Other Pests

Spiders and silverfish, house spiders and cellar spiders are all common species, with house spiders being larger and more robust. While generally harmless, their webs can be unsightly. Silverfish are small, wingless insects around 10-12 mm long, with a silver-grey colour and a tapered, fish-like appearance. They prefer damp, dark areas and can damage books, papers, and clothing.

Preventive Measures

To minimise the risk of pest infestations, it’s essential to keep your home clean and tidy. Regularly vacuum, dispose of rubbish, and clean up spills and crumbs promptly. Seal potential entry points, such as cracks and gaps around doors and windows, to prevent pests from entering your home. Store food in airtight containers and avoid leaving pet food out overnight.
