New Study Reveals England's Most Pest Infested Counties

The last thing anyone wants in their home is unwanted guests, pests can be a real nuisance and prove difficult to eliminate. They like to bite holes through walls and furniture whilst scavenging for any leftover food. During the summer months, they are most active, so members of the public might currently be noticing an increase in pest problems.
So here at Household Quotes, we decided to conduct an investigation into which English counties are the most and least pest-infested. We did this using Google search data which revealed how many people in each county were searching for different pests.
Research revealed Greater London, Bristol, Merseyside, West Midlands and Greater Manchester as the most pest-infested English counties.

1. Greater London
Greater London is the capital city of the United Kingdom, and according to Road Genius, 20.3 million people visited it in 2023. With a high amount of tourists, added to a large population of around 8.9 million, this produces a lot of waste. The city requires an efficient waste management system, but it’s clear from these results that Greater London has a pest problem. It ranked as England’s most pest infested county in this study, with one in every 146 people researching pests each month.
2. Bristol
Bristol ranked as the second most pest-infested county in England. Located in the southwest, only a few miles away from the Welsh border, the City of Bristol has a population of just over 479,000. It’s popular with students, as it’s host to two universities, and this has given the city a reputation for partying and art. Rats and pigeons were the pests that particularly stuck out in the city’s average monthly search volumes, with there being 1,000 and 720 respectively.
3. Merseyside
Merseyside which is home to settlements including; Liverpool, St Helens and Birkenhead ranked as the third most pest-infested English county. Pigeons prove a real problem with around 1,600 searches a month on average. It was discovered that there is one pest search a month for every 220.5 people in Merseyside.
4. West Midlands
The West Midlands is home to England's second most popular city Birmingham. It saw high searches for pests like rats, pigeons, cockroaches and ants which was enough to place it as the fourth most pest-infested county. This could be down to the county being urban and very densely populated, offering more food sources to potential pests.
5. Greater Manchester
Greater Manchester is made up of many different towns and cities, including; Manchester, Salford, Wigan, Bolton, Rochdale, Bury and Oldham to name a few. Due to the large population, and many frequented town centres, it may come as no surprise that Greater Manchester was ranked fifth in this study. Like the West Midlands, Greater Manchester has a clear pigeon problem due to the sheer number of searches each month (2,900).

‘’Pests are a real nuisance, so at Household Quotes, we were keen to see if pest problems differed depending on where you lived in England.
Through the results, you can identify areas with more pest concerns than others. A big factor that might explain the differences is population density, as some counties are more rural and others are more densely populated.’’

1. Leicestershire
Leicestershire is located in the centre of England and contains many large settlements. These include; Leicester, Loughborough, Hinckley, Market Harborough and Melton Mowbray. It has been ranked as the least pest-infested English county in this study, with minimal search rates for pigeons (480) and rats (720) when compared to counties with similar populations.
2. Nottinghamshire
Nottinghamshire is a county notorious for the tales of Robin Hood, stealing from the rich and giving to the poor. They ranked second behind their neighbours Leicestershire in this study. The county is home to Nottingham, Mansfield, Newark and Worksop, all of which have town centres which are popular with locals. However, these settlements are more spread out than those in Greater Manchester and Greater London, which could be a big reason for the lack of pests in the county.
3. Gloucestershire
Gloucestershire is a pretty rural county and is renowned for its farmland. It hosts one of the most famous service stations in the UK, which sells a variety of local produce. It was ranked as the third least pest-infested English county in this study. Like Nottinghamshire, this could be down to its large rural population.
4. Norfolk
To find the fourth least pest-infested English county we need to travel to Norfolk in East Anglia. It’s particularly popular with tourists, with thousands heading to Cromer, Hunstanton and Great Yarmouth every year. It will come as a huge relief to farmers that Norfolk seems to have a low pest problem compared to the rest of the country. Norfolk has averaged 2,130 pest searches on average per month over the past year.
5. Northumberland
Northumberland is one of England’s border counties, it sits north of Newcastle and south of Scotland. Like many others in the top five, Northumberland is a very rural county, and according to the Telegraph, it is the least densely populated county in England. The county has an average pest search per month of 790, which is low even for the smaller population of around 320,000.
