Why Choose Corky's

Our spider control service provides the best value for the money. No two properties are alike, therefore, we customize our services based on our knowledge of why spiders come to your property, where they are likely to take up residence, and how best to control them.

Corky’s Spider Control Service Details

Your technician will begin the service by removing spider webs in the eaves and around fence lines. Using low-impact and/or botanical treatments, that are proven effective spider solutions, he will then treat obvious areas of infestation, harborage areas and places where he knows or suspects spiders to be, (like under patio furniture). He will also treat the landscape plantings that attract other insects that provide food for the spiders.

In order to effectively control spiders, routine maintenance is of utmost importance. Re-infestation can occur rapidly as they migrate from or are carried by winds from neighboring yards, fields and canyons in their relentless hunt for food, water and shelter.

It's Raining Spiders

How do spiders get in your home and yard?

Spiders fly or rather float on air currents to find better places for survival. As new spiderlings they release several silk threads that form a kind of parachute. This parachute carries them with the wind. This behavior is called ballooning or kiting. Not all survive the trip which can range from just a few meters to several hundred miles.

Spiderlings can land anywhere: plants, fences, pool equipment, patio furniture, doorways and window sills. When they land, they crawl to the nearest shaded area for protection. Immediately they begin building a web to capture food and have a safe place to continue growth. As the spiders continue to grow, so does the size of its web, becoming massive as time passes.

Many spiders live for a year or longer depending on the species. The ones that land on your property during a spring breeze will mature to adulthood by the time fall rolls around. Most species stay outside all the time and never come in houses. However in autumn, mature male house spiders start to move around in search of mates. Although most remain outside, some might be drawn by your home’s heat and will venture inside if they come across an easy entry point.


We are confident that the service we provide will meet or beat your expectations for the control of spiders on your property. If in the event, our initial efforts do not afford you the control you expected and subsequent corrective measures are unsuccessful in this regard, we will refund the amount of your last paid service.

A landscape tick, mosquito, aphid and whitefly prevention control treatment is included in the Ant Service as a free added benefit. There is no implied guarantee for these insects as ticks may be brought to the property by skunks, opossums, rats and other outside sources that are beyond our control and flying insects, mosquitoes, aphids and whitefly, fly in from outlying areas surrounding the properties that we treat and are therefore not included in any guarantee.

Most spiders are venomous but not harmful

Black Widow Spider
Brown Widow Spider

There are over 40,000 different species of spiders. With the exception of the Uloboridae family, all spiders are venomous. Spiders are 8-legged animals (arachnids) with two part bodies (cephalothorax and abdomen), biting chelicerae, each with a long fang, and silk glands (from which the web is made) that open through spinnerets at the end of the body. They have 8 eyes and breathe air with lungs located on the underside of their bodies.

Here are some common spiders you'll find in Southern California.

Black Widow Spider

Appearance: Black widow spiders are known for the females' unique appearance and tendency to eat their mates. They are considered the most venomous spiders in North America; however, their bite is rarely fatal to humans. Male and female black widows look different. Female black widows are about 1.5 inches long. The males are about half the size of females and are lighter in color, with red or pink spots on their backs. The females are the most distinctive, with shiny black bodies and a red hourglass-shaped marking on the underside of their round abdomen. An important characteristic of this spider is its comb foot. This comb, a row of strong, curved bristles is located on the hind pair of legs and is used to throw silk over captured prey. Black widow spiders eat other spiders and insects that get caught in their webs. The female spider hangs upside down from her web as she waits for her prey. By doing this she shows off her bright markings, which†are a warning to predators that she is toxic.

Life Cycle - Black widows are primarily solitary creatures, with the exception of late spring when mating occurs. Female spiders can live up to three years. Males will live for one or two months. The female often kills and eats the male after mating, providing her with a ready supply of protein which is necessary for the offspring developing inside her. The female creates light tan papery, round and smooth egg sacs that contain between 200 and 900 eggs each. The eggs hatch after about 30 days. The baby spiders are cannibalistic and few survive the three-month period of development to adulthood.

Habitat - Black widow spiders inhabit most of the warmer regions of the world and throughout the american southwest. They are shy in nature, preferring dark, dry and secluded areas such as the underside of ledges, rocks, plants and debris, in barns, garages, basements, out buildings, hollow stumps and unoccupied rodent holes, mostly wherever a web can be strung. Cold weather or drought may drive these spiders into buildings.

Health Concerns - Rarely do spiders bite, but be diligent if a black widow bites you. Acute pain symptoms usually start within 20 minutes to one hour after the bite. Reactions vary from person-to-person depending on their health and age. The decision to seek emergency care should be made early. If the person who was bitten by a black widow spider has more than minor pain or has whole-body symptoms, seek care at a hospital emergency room.

Brown Widow Spider

Appearance: The brown widow†is slightly smaller†and lighter in color than its black cousin; the color can range from tan to dark brown to black, with shades of grey. Like its black cousin, it has a prominent hourglass-shaped design on the underside of the abdomen; the brown widow's hourglass, however, is usually a vivid orange or a yellowish color. It also has a black-and-white geometric pattern on the top side of its abdomen. As the spider matures its coloring darkens and this pattern becomes less noticeable. Also, they have distinctive stripes on their legs. Brown widows are most often identified by their egg sacs. Their distinctive round and spiked eggs sacs, differentiates them from the black widow egg sacs that are round and smooth in appearance.

Life Cycle: Brown widows live from 1 to 2 years and they produce approximately 20 egg sacs containing 120-150 eggs per sac over a lifetime. Spiderlings will hatch in approximately 14 to 21 days but remain inside the egg sac for 4 days to one month. They will then emerge from the egg sac, molt and begin eating but remain in the nest area for several weeks after which they will perform their amazing, ballooning act, as they instinctively venture into the world on favorable winds, looking for food, water and safe harborage. This species can breed all year long.

Habitat: The brown widow builds its web in secluded, protected areas around homes and buildings. Some typical sites include inside old tires, empty containers (buckets and nursery pots), mail boxes, entry way corners, under eaves, stacked equipment, cluttered storage closets and garages, behind shutters, recessed hand grips of plastic garbage cans, undercarriages of motor homes, underneath outside chairs and tables and in landscape plantings.

Health Concerns: This spider is not aggressive and will retreat when disturbed. Most bites occur when it is accidentally pressed against the skin of a person. A bite from a brown widow does require urgent medical treatment. In a lot of cases, a bite will only cause pain; in other cases, a red mark will occur at the site and still others may have a more serious even fatal reaction. In California, the brown widow is quickly displacing the black widow population.

Red Back Jumping Spider
Orb Weaver Spider

Red-Back Jumping Spider

Appearance: There are many different kinds of jumping spiders but in California, the red-back jumping spider is the most recognizable. Jumping spiders average about 3/8" in length and the female spider is generally larger than the male. They are typically brightly colored, sport very unique patterns, are hairy and sometimes thick bodied. Four pair of eyes give it extremely sharp 360 degree vision. It can see better than almost any other animal of the same size. Having the ability to turn its breast around 45 degrees is another of it's amazing talents. The back of a red-back jumping spider is distinctly red, with a black strip if it is a female. The rest of the body is usually entirely black. This tiny spider is a daytime hunter and will jump long distances (5 times the length of its own body) to catch its prey. Prey being small insects. It does not spin webs but creates a funnel shaped silken nest in which to hide and where the females lay their eggs.

Life Cycle - Before mating, the male walks toward the female, then backs away. He performs a kind of zigzag dance, and some males produce a sound by twitching their abdomens while dancing. Sometimes the male is killed after mating. A female jumping spider builds a silk case around her eggs. She will then stand guard over them until they hatch. Young jumping spiders emerge from the egg sac looking like miniature versions of their parents.

Habitat - Red-back jumping spiders can be found everywhere if the sun is shining; on trees, in the grass and under rocks. They can also be found in their tubular, silky nests beneath debris, wood, or anywhere undisturbed on the ground. Since this spider is a sight hunter, it stays in its nest during nights and when the conditions for seeing prey are poor.

Health Concerns: Jumping spider bites are not considered harmful to humans, especially since they tend to avoid humans rather than attack. While jumping spiders do produce venom, this venom is not considered a health concern.

Orb Weaver Spider

Appearance: The orb weavers (Araneidae) are one of the three largest spider groups. Their webs consist of radiating strands, like spokes of a wheel, and concentric circles. Most orb weavers build their webs vertically, attaching them to branches, stems, or manmade structures. Webs may be quite large, spanning several feet in width and round in shape which is where this family of spiders gets its name. Orb weaver spiders possess eight eyes, arranged in two rows of four eyes each. Despite this, they have relatively poor eyesight and rely on vibrations within their web to alert them to food. Orb weavers have four to six spinnerets, from which they produce strands of silk. Many orb weavers are brightly colored, and have hairy or spiny legs.

Life Cycle - Males are much smaller than females, and after mating may become her next meal. The female waits on or near her web, letting the males come to her. She lays eggs in clutches of several hundred that are cocooned in a silken sacs. In areas with cold winters, the female orb weaver will lay a large clutch in the fall and wrap it in thick silk. She will die with the first frost, leaving her babies to hatch in the spring. Orb weavers live, on average, one to two years.

Habitat - The orb weaver's web is designed to entrap meals efficiently. The spokes of the web are mostly non-sticky silk, and serve as walkways for the spider to move about the web. The circular strands are sticky and insects become stuck on contact. Habitat: Orb weaver spiders live throughout the world, with the exceptions of the Arctic and Antarctic regions. In North America, there are approximately 180 species of orb weavers. Worldwide, there are over 3,500 species in the family Araneidae. They live anywhere that provide abundant prey and structures to support the web - around light fixtures used at night, or tree branches, tall grasses, and bushes.

Health Concerns - Orb weavers are non-aggressive spiders that will run at the first sign of a threat (they will run or drop off the web). They are not dangerous to people or pets, and are actually very beneficial because they will catch and eat a lot of other insects.

Wolf Spider
Brown Recluse Spider

Wolf Spider

Appearance: Wolf spiders are usually, brown, grey, black or tan, with dark markings (usually stripes). Their coloring is an effective camouflage, helping them catch their prey and keep safe from predators. They range from a quarter of an inch to over an inch long, with males usually smaller than females. They have a distinctive eye arrangement, where the front row is composed of four small eyes of roughly the same size arranged in almost a straight line. The back row is arranged in a V-pattern with the point next to the back row. Wolf spiders have excellent night vision, and primarily hunt in the dark. They are easily detected at night due to their eye shine.

Life Cycle - The males signal their interest to females by waving their pedipalps (short, sensory appendages near their mouths) in special patterns or banging them together. After mating, female wolf spiders lay several dozen or more eggs and wrap them in silk, creating an egg sac. Female wolf spiders carry their egg sacs attached to her spinnerets (silk making organs). If the female loses her egg sac, she will search for it. Females are known to be most aggressive when carrying their egg sacs. After hatching, spiderlings climb on their mother’s back and she carries them around for several days. The baby spiders, then migrate to new territories by the process of ballooning. (Spinning silk threads that catch a friendly breeze, carrying them away.) Male wolf spiders typically live for one year or less, while females can live for several years.

Habitat - Wolf spiders are common throughout the United States, especially Missouri, Texas, and California. These spiders are solitary in nature and roam alone at night, stalking prey. They live on the ground, though some are known to climb partly up trees to catch their prey. Some species hide in vegetation or leaf litter, while others dig tunnels or use another animals tunnels. Some wolf spiders hunt in a set territory, while others wander with no territory or home. Wolf spiders eat mostly ground-dwelling insects and other spiders. Especially large females may eat small vertebrates. Some species chase down then grab their prey, while others wait for it to walk by and pounce on it, then hold it between their legs and roll over on their backs, trapping their prey with their limbs before biting it. Keen eyesight, camouflage coloring, speedy movements and high sensitivity to vibrations keep them safe from predators.

Health Concerns - Wolf spiders are often confused with the brown recluse, but they lack the unmistakable violin-shaped marking behind the head. The wolf spider is shy and will run away when disturbed. They will however bite when threatened. The bite of the wolf spider is not a significant medical threat to the average adult.

Brown Recluse Spider

Appearance: These typically brown to grayish colored spiders have a body length of about 3/8" inch (but can grow larger), with very long legs. They have six eyes arranged in pairs (dyads) with one middle pair and two side pairs. These spiders usually have markings on the top side of their cephalothorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames of fiddleback spider, brown fiddler, or violin spider.

Life Cycle - The female will lay 40 to 50 eggs in a silken casing, producing 1-5 casings during her lifetime. The spiderlings hatch and go through one molt inside the egg case before emerging into the world. After emerging, the instars go through 6-7 more molts in the nest during the next 7 to 12 months before becoming adults. The adults live 1-2 years.

Habitat - Brown recluse spiders build irregular webs that include a shelter consisting of disorderly thread. They build their webs in woodpiles and sheds, closets, garages,†basements, and other places that are dry and mostly undisturbed. When living in human residences they seem to favor cardboard, possibly because it mimics the rotting tree bark which they inhabit naturally. They have also been found in shoes, inside dressers, in bed sheets of infrequently used beds, in clothes stacked or piled or left lying on the floor, inside work gloves, behind baseboards and pictures, in toilets, and near sources of warmth when temperatures are lower than usual. Human contact often occurs when isolated spaces are disturbed and the spider feels threatened. Unlike most web weavers, they leave their webs at night to hunt. Males move around more when hunting than do females, which tend to remain nearer to their webs. The spider hunts for†firebrats, crickets,†cockroaches, and other soft-bodied insects. The natural range of this spider is roughly south of southeastern Nebraska through southern Iowa, Illinois, and Indiana to southwestern Ohio. In the southern states, it can be found from central Texas to western Georgia and north to Kentucky.

Health Concerns - Brown recluse spider bites often go unnoticed initially because they are usually painless bites. The venom is extremely poisonous, even more potent than that of a rattlesnake. The venom of the brown recluse is toxic to cells and tissues. If you think you or someone you know has been bitten by a brown recluse spider, then the individual should be seen by a doctor that day. If you can, bring the spider in question to the doctor's office.

Rick Vetter, a renowned research entomologist at the University of California, Riverside, states that as of this writing there has never been one single Brown Recluse spider bite verified in the State of California. This species of recluse spider is only found in the Midwest and South United States. There are other types of desert recluse spiders found in the southwest deserts and sometimes in urban areas and there are several other spider species often misidentified as the fearsome "Brown Recluse". There have also been numerous documented infectious and noninfectious conditions that produce wounds that have been initially misdiagnosed as brown recluse bites by medical professionals.

Seal and close any entry points into your home.

What works best to keep spiders from entering your home? Close any holes, gaps or openings around your home. Keep things tidy, clean and bright. Most spiders remain outside but they will seek warmth and shelter inside if they come across an easy entry point.

Pruning Plants
Sealed Trash Bins
Bug Light

Here are some do-it-yourself spider control recommendations:

Outside Prevention

  • Clean up wood piles and remove other debris that can create hiding places.
  • Keep shrubs pruned and far enough away from your home to allow sun and air to penetrate the space between them and the house.
  • Remove webs from eaves, fences, play structures, patio furniture, decks, and other items in your yard.
  • Keep trash bins covered and away from the house. Clean trash bins periodically.
  • Use yellow or sodium vapor bulbs for outdoor lighting to reduce the lights' attractiveness to insects that are the food source for spiders.
Storage Containers
Seal Entry Points

Inside Prevention

  • Vacuum up spiders, egg cases, and webs. Use the crevice tool to get into all cracks and crevices. Your vacuum is your best tool!
  • Remove clutter and control humidity in attics, basements, and other dark areas. Seal stored boxes with tape or use plastic storage boxes with tight sealing lids.
  • Spiders generally enter homes through cracks and crevices around the foundation, or doors and windows. Install door sweeps. Seal or caulk entry points and make sure windows and doors fit tightly.
  • The use of pesticides indoors may help control other insects that spiders feed on, but they don’t provide long-term spider control.
