How to keep spiders out of your house
Unfortunately for some people that suffer arachnophobia spiders play an important part in the ecosystem and have done so for millions of years with some species found preserved in amber long long ago which still survive to this very day unchanged.
Some more tips on keeping spiders out of the house which come in from outside. A few tips will help reduce the numbers of spiders entering the home if followed. Firstly bodies of water eg fishponds, small dams, small “soaks” etc will attract spiders as they are a breeding ground for many small insects such as midges and mosquitoes, pond skaters, dragon flies etc.
Many species of spiders are opportunistic feeders so this activity is a virtual smorgasbord for spiders and they will usually find a great selection on the menu. When the pickings are good they will of course take advantage of the micro habitat and what it has to offer in the way of a food source and with a good food supply they will take advantage of this also and breed prolifically, I hate to say this but you will never fully get rid of spiders in the home there will always be one, having said that please read on.
The over use of pesticides for spiders is another thing to avoid, the reason for this is that pesticides unlike some herbicides are non selective meaning they kill pretty much everything. This is not ideal if you are trying to reduce the numbers of spiders in the garden as pesticides will kill off the spiders natural predators also. Without any natural predation the spider numbers will increase dramatically- remember that spiders are not on the top of the food chain in the garden.
It is important to bear in mind that pesticides will also kill off any microscopic organisms that live in the soil that maintain a healthy microbial system and soil condition. Once this is lost the plants will then become stressed and stressed plants tend to attract insects and we know what the insects will attract right? Pesticides as far as im concerned have only one place and that is in the bin, better results can be achieved organically and biologically rather then using soil persistent pesticides and herbicides.
Homes situated out in the open such as large paddocks or open fields devoid of trees are sometimes more susceptible to spider infestations and spiders in house can make a lot of people feel real uncomfortable. Small airborne spiderlings can float on the winds and currents for many miles unhindered from snags such as trees and other vegetation that they usually get caught on. This in turn causes them to end up on the sides of houses or on the roof where they set up camp.
Areas such as this with little to no vegetation has very low bird numbers, little to no bird numbers means one of the spiders worse enemies in way of predation will make it easier for spiders to get a foot hold in the area as the numbers are not being kept in check by the birds so getting rid of spiders outside ends up a problem if the apex predator has no habitat.
Spiders will then seek out a controlled temperature environment of warmth during the winter months and cool during the summer to hunt and mate so you end up with spiders in the house. They will find a way in through damaged fly screens, under doors, under the roof tiles, any cracks or crevices, spiders have an amazing ability to squeeze through the smallest of gaps and gain entry.
Vacuuming personally I think vacuuming is the best method of ridding the house of spiders (well dramatically reducing their numbers anyway) but the thing is they are very good at keeping out of the way. When vacuuming spiders up be sure to do it thoroughly.
The places spiders love to hide is in behind the fridge, washing machine, under the couches and chairs, behind ovens, behind wall paintings, don’t forget curtains! everything must be upturned and vacuumed, also suck up any egg sacks you see and other insects (spider food)
Killing spiders for me personally is not something i enjoy doing as I do not dislike spiders although I am an arachnophobe. I have a strong interest in spiders or for anything with claws, teeth or venom for that matter, they interests me so if need be try to remove spiders from the home humanely after all they are just doing what comes natural and that is following a basic hardwired instinct and that is survive and reproduction.
How to get rid of spiders in the house
Spiders are primarily insect eaters and depending on the species are either entering the home to seek warmth during the cooler months or are hunting. Certain species of spiders can detect warmth coming from underneath the bottoms of doors around windows or in through the roof as warm air rises up and escapes through the roof. The best way to reduce the number of spiders entering the home is to remove their food source by way of keeping insect numbers down in the home giving them less reason to enter or take up residence. Also it is a good idea to trim all trees and hedges back from the house and also if you live in a brick home block the weep holes at the bottom of the brickwork with old stocking or similar to keep spiders out but also let the wall cavity breathe, following these simple tasks should dramatically reduce and prevent spiders in house, also all fly screens and door screens should be checked for holes and make sure they sit flush in their frames.

1) Firstly put the glass over the spider without pinning the legs of the spider.
2) Then slowly and carefully slide the paper underneath the glass.
3)When the paper is completely underneath the glass just slowly pick up the glass and paper (or cardboard) making sure not to create any gaps between the glass and paper or the spider might get out.
4)Then turn the glass upright keeping the glass covered at the top with the paper.

The Daddy long legs spider is very common and found in most homes within Australia and there has been much misconception when it comes to the Daddy long legs spider whether or not it is in fact the worlds deadliest spider? so is the Daddy long legs poisonous?
The Daddy long legs spiders are in fact venomous and possess venom glands as well as fangs that are very tiny but are completely harmless to humans but they do prey upon Redback spiders also the Comb footed spider preys on redbacks as well. Redbacks are venomous to man and have caused 14 deaths to date in Australia. There is an anti-venom for Red back spider bite. The Daddy long legs spider I am sure we have all heard of before are a great defense against the Australian Redback spider and how to get rid of spiders and are completely harmless, the only drawback to having the Australian Daddy long legs spider in your home is their unsightly messy webs they build (usually in a corner of the room) besides this they are a great way of getting rid of spiders, the female redback of the species is easily to recognize by her shiny black body and bold red stripe on the upper side of the abdomen when in an adult phase, in the immature phase the females are smaller and usually brown with whitish markings. Redback spiders are found throughout Australia and are a very common species in and around dry areas such as up underneath outdoor furniture, empty cardboard boxes, timber piles etc, Note: some insecticides are not effective against Red Back Spiders.
It is interesting to note that it has been thought that the redback spider is actually not a native to Australia? and there is a relation between them and the New Zealand katipo and also the American species of black widow spider, the Katipo, black widow and the Redback are all the same genus and that is the genus of latrodectus, the latrodectus or widow family of spiders are found world wide and are neurotoxic, in Europe they are known as Malmignatte, Russia the Black Wolf, Arabia Jockey Spiders, and South Africa they are known as Swart Knopiespinnekop
The Male redback spider does not produce a web and is smaller than the female being only around 3 to 4 millimeters in length and interestingly the Redback is one of a few arachnids which display sexual cannibalism where the female of the species will actually kill and consume the male after mating and in some cases during (sounds like a woman I once knew) it is believed by Biologists that this occurs as the nutrients the female will gain from the male will help in egg development and maintaining a healthy condition.
There is no real need to panic if you should come across a redback spider as they are a fairly shy species that if confronted would much rather escape and avoid confrontation at any cost pretty much the same as snakes, if cornered and threatened especially when protecting her egg sac the female redback spider will become very aggressive and in some cases bite which is only natural as it is protecting its young to be.
