As their name implies, these spiders are commonly found within the home environment. This species if prevalent throughout the whole of the British Isles, but they are generally more common in the warmer southern regions of England. House spiders can range from 0.5 to 1.0cm in size and like to make webs in garden sheds and garages. Crawling insects and worms that make their way into outbuildings are the favourite food of the House Spider, and they thrive in these areas sheltered from the weather. Whilst Britain doesn’t have any known venomous spiders; it is worth staying vigilant due to the transportation of foreign spiders in imported produce.
Whilst all spiders have a certain capability of venom or poison, very few are aggressive towards humans and even fewer can bite with the risk of serious harm. The most infamous varieties include;
Black House Spiders
Unfortunately this species likes to build its web inside buildings which puts it in the vicinity of humans. Attracted to the house by the lights, which in turn attracts their prey of insects, the black house spider can bite with harmful venom. Their bites are rarely fatal but it’s worth practicing caution around these black spiders with grey abdomens.
Brown Recluse Spiders
Measuring between 0.5 – 2.0cm, Brown Recluse Spiders are found in dry areas which are not likely to be disturbed on a regular basis. Also known as violin spiders because of their instrumental markings, they can be found in disused storage such as cupboards, and outbuildings. True to their name, they are not very aggressive but will bite when cornered and/or threatened by an intimidator. Steering clear will often be the safest approach; because they have a bite which can act very quickly can cause organ damage and fatality.
Black Widow Spiders
Perhaps the most widely known of all venomous spiders, Black Widows are identified from the hourglass markings upon their stomach or back. As one of the most dangerous of all spiders, their bite can easily kill children, the elderly or those with a pre-existing medical condition. Mainly living outside in cluttered areas, the Black Widow preys on insects and those with composting bins are at the most risk of encountering them.
Getting Rid of Spiders
As with most things, the simplest method is often best. Trapping a spider beneath a glass and slipping something solid beneath it limits both its movement and its ability to attack you. Releasing them at a distance from the home often negates the need to kill the spider, as it will unlikely be able to find its way back. For those inclined to avoid any contact with the spider, another option is to buy a Spider Catcher from Pest Control Supplies.
D.I.Y Spider Prevention
Getting rid of spiders isn’t always a job for professional pest control; there are a variety of methods available to the amateur catcher. Sealing points of entry to the home is the best way to prevent insect access (windows, vents, doors, cracks, holes) but sometimes this can be impossible.
If possible, keep your house clean from clutter and try to “de-clutter” on a regular basis. Vacuuming those areas prone to clutter which may attract spiders or areas with known holes or cracks, is a good way to remove spiders and their nests.
Preventing spiders from returning is the crucial point in the process, otherwise all your effort will have been in vain. Insecticide will deter all crawling insects with a chemical deterrent; good brands include Digrain Insectaclear C, which can act for almost a month. Ensure that no contact is made with the insecticide covered surfaces until it has dried.
Areas prone to spiders should be treated regularly, and for those who want to avoid chemicals then mint is a great alternative, spiders detest the scent.
