Many people will probably be glad to know that spider mating-season won’t be lasting very much longer and soon those male spiders will be very few and far between. Now here’s something a little different from the micro jungle, a Zebra Jumping Spider with a woolly aphid as prey. Also from the microcosm, here’s a little moth you will commonly see feeding on flowers during daylight hours in summer, the Nettle-tap Moth. Now is the time to see spiderlings emerging, and the most spectacular are those of the orb-weaver spiders. The cellar spider (Pholcus phalangioides) is sometimes called the daddy long-legs, but unhelpfully, this refers to at least two other whole groups of animals, the harvestmen, and the crane-flies, neither of which are closely related. The cellar spider below is currently living behind my bedside-table, coming out at night to hunt. Araneus diadematus, the garden orb-web, currently neither in a garden, nor in possession of an orb-web.The largest spiders in the UK, in terms of overall leg-span, are the various funnel-web house-spiders of the genus Tegenaria.
The domestic house-spider has just the right mixture of size, chunky-leggedness, speed and fearlessness to cause worry in even the non-arachnophobic, but it’s usually docile and its bite is generally regarded as clinically insignificant. I’ve spent a lifetime telling people how cute and useful and harmless British spiders are, and that people should leave them alone rather than splatting them with a shoe. This harmelss spider spins orb webs and can be found blocking your way having strung its web across paths, and door frames.
This spider superficially resembles, and is frequently confused for, a spider whose bite has been reported to be 15 times stronger than a rattlesnake. These spiders are commonly seen between June and November when the first frosts kill them off. There have been lots of stories about deadly spiders invading the UK, but the ones we're most likely to meet won't bite. SLO Pest and Termite - Spiders     Many people fear or dislike spiders but, for the most part, spiders are beneficial because of their role as predators of insects and other arthropods, and most cannot harm people.
Autumn is a particularly good time to go spotting the spiders that cohabit with us, as many of them are grown fat and sleek on the flies of summer, and are therefore easy to spot.
There is a myth that this spider has incredibly toxic venom and it’s only the stumpiness of its fangs that prevent it being lethal, but this is tosh.
This one is was called MarloweWhen disturbed, the cellar spider does a bonkers dance in its web, which I find endearing. When I was a kid, there was a mahoosive giant house spider that lived in my parents’ shed, which in my mind was the size of dinnerplate, but in reality was probably only about the size of a Jaffa Cake. How very human.The best spiders in the whole world are the jumping spiders, and if anyone disagrees, they are simply wrong.
Spiders that might injure people—for example, black widows—generally spend most of their time hidden under furniture or boxes, or in woodpiles, corners, or crevices.
If you’re an arachnophobe, there is every reason to leave this spider alone, as one of the things it eats is other spiders.
I may be mistaken, but I think it’s a false widow spider (Steatoda nobilis), a non-native species that arrived in the UK, possibly on shipments of bananas.
The spiders commonly seen out in the open during the day are unlikely to bite people. IDENTIFICATIONSpiders resemble insects and sometimes are confused with them, but they are arachnids, not insects. Putting it outside will kill it at this time of year, as they’re essentially a subtropical species that has colonised the subtropical boxes humans brought with them as they spread across the globe. That scientists are not currently trying to breed zebra spiders the size of kittens is a damning indictment of the way grant money is awarded by the Research Councils. Although spiders often are found on plants, they eat mainly insects, other spiders, and related arthropods, not plants. However, only those spiders whose venom typically causes a serious reaction in humans are called “poisonous” spiders. Common Spider Families in North America.Agelenidae, funnel weavers or grass spidersSit-and-wait predators feed during the day and night on the ground in most types of vegetation, including low-growing plants and trees. When it detects vibrations from an insect that flew or walked into the web, the spider runs out, captures and bites the prey, then carries it back into the funnel to be eaten. About 300 species in North America.Araneidae, orb weavers or garden spidersFeed on insects that fly, fall, or are blown into web. Spiderlings often make symmetrical webs; mature spiders may spin a more specialized design that is helpful in identifying certain species.


The spider rests at the center of its web or hides in a shelter near the edge, waiting for prey to become entangled. About 200 species in North America.Clubionidae (including Corinnidae), sac spiders or twoclawed hunting spidersStalk and capture prey that is walking or resting on surfaces. About 200 species in North America.Linyphiidae (=Microphantidae), dwarf spidersPrey on insects that fall, walk, or land in their web. Several hundred species in North America.Lycosidae, wolf spidersPrey on insects that are walking or resting on the ground. About 200 species in North America.Oxyopidae, lynx spidersStalk and capture resting or walking insects. About 2 dozen known species in North America.Salticidae, jumping spidersDay-active hunters in plants or on the ground. About 300 species in North America.Theridiidae, cobweb, cobweb weaver, or combfooted spidersFeed on insects that walk or fly into their webs. The spider is usually concealed in a corner of the web, in a silken tent, or behind debris. This group includes the black widow spider, which produces relatively thick silk that feels rough and sticky. Over 200 species in North America.Thomisidae, crab spiders or flower spidersStalk and capture insects walking or resting on surfaces. Over 200 species in North America.Spider BitesUnlike mosquitoes, spiders do not seek people in order to bite them. Generally, a spider doesn’t try to bite a person unless it has been squeezed, laid on, or similarly provoked to defend itself. Moreover, the jaws of most spiders are so small that the fangs cannot penetrate the skin of an adult person. Sometimes when a spider is disturbed in its web, it may bite instinctively because it mistakenly senses that an insect has been caught.The severity of a spider bite depends on factors such as the kind of spider, the amount of venom injected, and the age and health of the person bitten. A spider bite might cause no reaction at all, or it might result in varying amounts of itching, redness, stiffness, swelling, and pain—at worst, usually no more severe than a bee sting. Like reactions to bee stings, however, people vary in their responses to spider bites, so if the bite of any spider causes an unusual or severe reaction, such as increasing pain or extreme swelling, contact a physician, hospital, or poison control center (in California, the number is 1-800-222-1212).Sometimes a person may not be aware of having been bitten until pain and other symptoms begin to develop. If no one there can identify it, ask that it be forwarded to a qualified arachnologist.Black Widow SpiderThe black widow spider, Latrodectus hesperus, is the most common harmful spider in California. Only the larger immature female and adult female spiders are able to bite through a person’s skin and inject enough venom to cause a painful reaction.The adult male black widow is one-half to two-thirds the length of the female, has a small abdomen, and is seldom noticed. The hourglass mark on the underside of the abdomen typically is yellow or yellow-orange and broad waisted. In intermediate stages they have tan or cream-colored, olive-gray, and orange markings on the top side of the abdomen, a yellowish orange hourglass mark on the underside, and banded legs.Webs and Egg Sacs.
The web of the black widow is an irregular, tough-stranded, sticky cobweb mesh in which the spider hangs with its underside up. Tiny, young black widows, which are nearly white in color, disperse to new locations by ballooning and infest new areas.Where the Spiders Live. People are most likely to be bitten when they disturb the spider while they are cleaning out or picking up items in such places. A sensible precaution is to always wear gloves and a long-sleeved shirt when working in areas that have been undisturbed for a time and where there are good hiding places for spiders.Effects of the Bite.
Most people who are bitten spend a few hours under observation by a physician but do not develop symptoms severe enough to require treatment. This spider is light yellow and has a slightly darker stripe on the upper middle of the abdomen. The eight eyes of this spider are all about equal in size and arranged in two horizontal rows.Yellow sac spiders can be seen running on walls and ceilings at night and quickly drop to the floor to escape if they are disturbed.
Bites usually occur when the spider becomes trapped against a person’s skin in clothing or bedding.
It is estimated that sac spiders are responsible for more bites on people than any other spider. Typical symptoms of a bite include initial pain, redness, and sometimes swelling.Recluse SpidersRecluse spiders of the genus Loxosceles include the well-known brown recluse spider, L. While the brown recluse has occasionally been brought into California in household furnishings, firewood, and motor vehicles, it does not reside in the state.


Both the native desert recluse spider and the Chilean recluse spider occur principally in the drier areas of southern California.Recluse spiders can have a violin-shaped mark (with the neck of the violin pointing backward) on the top side of the head region (cephalothorax).
A unique feature of recluse spiders is their six eyes, arranged in pairs in a semicircle, which can be seen with the use of a good hand lens. Most other spiders have eight eyes.All recluse spiders make large, irregular, flattened, cobweb-type webs with thick strands extending in all directions.
These spiders avoid light, are active at night, and tend to build their webs in out-of-the-way places. Chilean recluse spiders may be found indoors in boxes, in corners, behind pictures, in old clothing hanging undisturbed, and in other similar places. The female spiders are black with red on the top side of the abdomen whereas the males are all red. These spiders ranges from 1 to 2 inches in body size.The hobo spider, Tegenaria agrestis, also called the aggressive house spider, is a common spider in the Pacific Northwest. The hobo spider has not been documented in California, but it has expanded its range from the Pacific Northwest to northern Utah, Wyoming, and Colorado. Although it has been stated as being a poisonous spider, recent research is challenging the original data that elevated this spider to medical importance.
Another is the marbled cellar spider, Holocnemus pluchei, which was introduced into the state in the 1970s and has since displaced the once common longbodied cellar spider, Pholcus phalangioides , a long-legged spider that resembles a daddy-longlegs.
Often these are fully grown wolf spider or tarantula males that have reached maturity and are searching for females. New houses and other structures in developments may be invaded by wolf spiders that have lost their usual outdoor living places. The more insects that exist inside a building, the more likely it is to have spiders living there.
Immature and adult female burrow-living spiders sometimes wander for a time during the rainy season if they have had to abandon wet burrows. MANAGEMENTRemember that spiders are primarily beneficial and their activities should be encouraged in the garden. The best approach to controlling spiders in and around the home is to remove hiding spots for secretive spiders such as black widows and regularly clean webs off the house with brushes and vacuums. Prevention and Nonchemical ControlSpiders may enter houses and other structures through cracks and other openings. Regular vacuuming or sweeping of windows, corners of rooms, storage areas, basements, and other seldom used areas helps remove spiders and their webs. Vacuuming spiders can be an effective control technique because their soft bodies usually do not survive this process.
Good screening not only will keep out many spiders but also will discourage them by keeping out insects that they must have for food.In indoor storage areas, place boxes off the floor and away from walls, whenever possible, to help reduce their usefulness as a harborage for spiders. Be sure to wear gloves to avoid accidental bites.Outdoors, eliminate places for spiders to hide and build their webs by keeping the area next to the foundation free of trash, leaf litter, heavy vegetation, and other accumulations of materials. Trimming plant growth away from the house and other structures will discourage spiders from first taking up residence near the structure and then moving indoors. Insecticides will not provide long-term control and should not generally be used against spiders outdoors. Chemical ControlTypically pesticide control of spiders is difficult unless you actually see the spider and are able to spray it. There are various insecticides available in retail outlets labeled for spider control, including pyrethrins, resmethrin, allethrin, or combinations of these products. If you spray a spider, it will be killed only if the spray lands directly on it; the spray residual does not have a long-lasting effect. This means a spider can walk over a sprayed surface a few days (and in many cases, a few hours) after treatment and not be affected.
It is just as easy and much less toxic to crush the spider with a rolled up newspaper or your shoe or to vacuum it up. Sticky traps offer a noninsecticidal way to remove spiders from your home as long as you can place the traps where pets and curious children can’t tamper with them.Sorptive dusts containing amorphous silica gel (silica aerogel) and pyrethrins, which can be applied by professional pest control applicators only, may be useful in certain indoor situations.
Particles of the dust affect the outer covering of spiders (and also insects) that have crawled over a treated surface, causing them to dry out. When applied as a dustlike film and left in place, a sorptive dust provides permanent protection against spiders.
