Around this time of year we can expect to see more spiders entering our homes in search of a mating partner. Most spiders found in the UK are not dangerous but keeping them out of your home can be easily achieved with five simple steps, according to pest control experts.
Paul Blackhurst, Head of the Technical Training Academy at Rentokil Pest Control, said: “September usually marks the beginning of mating season for spiders, leading to increased sightings across the UK as males leave their webs in the search for a breeding partner.
“This means that many spiders will potentially make their way into properties and homes through open windows, under doors and through gaps in buildings.
“In the UK there are around 650 species of arachnids, yet we can expect to see less than a dozen of these in our homes. Whilst many people fear them, most species that are found in the UK are not dangerous, and spiders are actually beneficial to our environment, providing a natural form of pest control, as they feed on insect pests such as flies, ants, beetles and moths.
“The most common species found in UK homes are the Lesser House Spider, which can grow to 17–20mm long, and the Giant House Spider, which can reach 25mm once they enter sexual maturity and if they have had access to lots of food. It is important to note that both of these species are extremely reluctant to bite, preferring to escape and hide.
“False widow spiders are a group of species that resemble the notorious black widow spider, and were accidentally imported to the UK about 150 years ago, with increased sightings in recent years as they adapt to our temperate climate. These spiders will only bite humans if they are provoked, with bites usually only causing a temporary pain and swelling at a similar intensity to a wasp sting. Rentokil Pest Control offers a False Widow Spider Monitoring Service, providing an accurate identification of the species before control measures are put in place.
“False widow spiders are nocturnal, and prefer to be hidden away in dark cracks close to their web, rarely venturing out during the day. They can be identified by their brown bulbous abdomens with pale markings, and the females can grow up to 15mm.
“Spiders are able to squeeze themselves through tiny gaps and holes, making it nearly impossible to completely protect your house against them, but closing doors and windows, and filling holes will help to keep them at bay.
“As with most pests, the best way to control spiders is to limit their food source. This includes clearing away any dead flies, or any other small, crawling insects.
Here are Rentokil Pest Control’s five top tips to make your home as unwelcome as possible to spiders:
1. Vacuum regularly – high and low
Make sure that you hoover the sheltered spots too, such as beneath worktops and behind cupboards and sofas.
2. Remove noticeable webs
This should be done on a regular basis, remembering to check the corners of the ceiling, picture frames and mirrors.
3. Fill gaps
Where possible, make sure that you fill in the gaps between walls, pipework and under the doors.
4. Remove sheltering sites
Spiders will look to tuck themselves away in your firewood piles, garden bags and any compost heaps that you have. Try and also store these items away from the house perimeter walls.
5. Deter all insects
As insects are drawn to light, and with flies and moths being ideal spider prey, it is advisable not to leave lights on unnecessarily.
