Start where they got in
Every one of these starts in the same place: something you cannot name, a quote you cannot judge, and explanations that cannot all be true. What you are actually looking at, how it got in, and what deals with that instead of clearing the ones you can see for a season.
Silverfish, and the second species nobody tells you about
The common silverfish cannot lay eggs unless it is damp, so drying the room out ends it. That advice is on every page about them, and it stopped being the whole answer in 2014.
House spiders, false widows, and what actually bites in Britain
Hospital admissions for spider bites in England have doubled in a decade. They went from 47 a year to 100. Both of those facts are true at once.
Woodlice indoors are a damp reading, not an infestation
They cannot breed in your house and they cannot survive a dry room. Both are the reason a woodlice spray is usually money for nothing.
A wasp nest, and whether it is actually your problem
A UK wasp nest dies over winter and is never used again. That turns the question from how to kill it into how close it is to you.
The moths you can see are not the ones eating your jumper
Adult clothes moths have no working mouthparts and eat nothing at all, which is why spraying the flying ones changes nothing.
Flying ant day is not a day, and you do not need to buy anything
The largest study done on this found flying ants on as many as 96% of days across the summer. There is no single date and nothing to treat.
Mice, and the 6mm gap that is doing all the work
A house mouse gets through a gap about the width of a pencil.
A rat in the garden is a different problem from a rat in the house
Outdoors it is food and shelter, and the animal may be living three hundred metres away on somebody else's land. Indoors it is a hole in your building.
Who is responsible for pest control: you, the landlord, the freeholder or the council
Most people arrive at this question assuming they are the one paying. In a rented home they usually should not be, and four separate pieces of law can say so.
