Spider Control
Spiders can bite and create unsightly webs.


Spiders are frequently seen across Philadelphia. While certain members of this species may be dangerous, this is not true for most of the local varieties.

Nonetheless, it can be aggravating to be constantly confronted with spider webs both indoors and out. They look unsightly, and no one likes to walk through them. When the population of spiders on a particular piece of property starts to seem overwhelming, then it may be time to request professional assistance. The presence of an inordinate number of spiders may indicate an additional problem that  should be diagnosed by a pest control company. With species like the broad-faced sac spider, common house spider, grass spider and wolf spider appearing in alarming numbers, the intervention of a Philadelphia exterminator may be a necessity.


Contrary to the popular misconception, spiders are not insects but arachnids. Other members of this family include ticks, scorpions and mites. They have eight jointed legs and a hard exoskeleton. Typically, their bodies feature an abdomen and a head and thorax that are fused together.

The broad-faced sac spider has a carapace that is brown or slightly red while their abdomen is yellow or gray. They have a dark dorsal stripe, and the front legs are noticeably thicker and darker than this spider's rear legs. Adult females generally measure seven to 10 millimeters in length while males are only about five to six millimeters.

With their chevron-marked bodies in muted tones of gray and brown, the common house spider has a distinctive appearance. Their legs are striped, and these spiders are quite small. Females may only grow to about eight millimeters in length while the males only achieve about half of that size.

The daddy-long-legs is easy to distinguish from other species because of its distinctively long and thin legs. Their bodies generally look quite a bit smaller than the bodies of other spiders as well. Body size ranges from two to 10 millimeters, but their legs may be as long as 50 millimeters. With colors of gray, black and tan being common, it is fairly easy for the daddy-long-legs to blend in with the surroundings.

Grass spiders may become quite large with females growing to 20 millimeters in length. Males typically only achieve about 18 millimeters in length. Their carapaces are yellow or brown and have dark stripes. Frequently, the legs are a lighter color proximal to the body than they are near the arachnid's feet.

Wolf spiders feature distinctive patterns on their bodies in shades of brown, grey and black. Some even exhibit shades of orange. Adults may be anywhere from half an inch to two inches in length. Instead of building a web, these spiders chase and pounce on their prey.


Spiders can be considered a necessary and beneficial species because of their eating habits. Insects like wasps, ants, mosquitoes, flies and many others are routinely consumed after being trapped in the spider's web. They will even eat other spiders. However, when too many spiders take up residence on a property, it may be a sign that there are too many other pests. A Philadelphia exterminator can determine whether or not an underlying pest problem is attracting spiders.


Spiders that hunt prey, like the wolf spider, commonly are found in dark, cluttered areas. These spaces provide plenty of cover in which to hide, making it easier for the wolf spider to pounce on its prey. Most of the spiders that are frequently seen in Philadelphia are web builders. To capture flying insects, spiders build webs in elevated places like the upper corners of doors, windows and porches. The corners of rooms are other likely places to find a spider web as are light fixtures.

Other spider species prefer to build their webs at ground level. They may use turf or soil as a background on which they can capture walking insects.


Spiders typically spin far more webs than they actually use. They will create a test web to see if they catch any prey. If unsuccessful, they will abandon the web and build another one elsewhere. With the ability to quickly create new webs, it is not long before the interior of a home or office begins to look neglected. In most cases, spiders simply cause an unsightly mess that must be cleaned up repeatedly.

It is also worth considering that many people have an elemental dislike or fear of spiders. Knowing that they have an infestation of spiders may be enough to keep some people from sleeping at night.


Spider activity may be noted in the day or night. This is because they may be awakened at any time by prey being trapped in their web. While some spiders are adept predators, most of them are still fearful of humans. Accordingly, they are more likely to avoid direct confrontations. This leads many spiders to build their nests and spend the majority of their time in out-of-the-way spots like basements, attics and garages. Clutter both indoors and out also may attract spiders as they look for a likely place to conceal themselves. This propensity for hiding may lead to an unpleasant surprise when an unsuspecting person starts sifting through the clutter. Bites, although rare, may occur when a spider is surprised or feels threatened.


Few health issues are associated with the spiders that are typically found in Philadelphia. Any medical concerns that do arise in connection with spiders are likely to be related to a bite. Most bites are accompanied by mild side effects like slight redness or momentary itchiness. Severe reactions are less common, but they do occur when someone has a sensitivity or allergy. With excessive swelling and pain, these bites may need medical attention.


Indications of a spider problem include:

An excessive number of spider sightings
Several spider bite events
Frequently being confronted with spider webs and cobwebs inside and outside structures


SafeGuard Pest Control recommends the following spider prevention methods:

• Have regular pest control treatments to control underlying issues
• Use screens on windows and doors
• Remove spider webs from structure exteriors at least once per week
• Keep to an annual schedule of power washing building exteriors
• Eliminate clutter from indoor and outdoor spaces
• Do not allow lawns to become overgrown
• Cut back trees, shrubs and plants so that they do not touch building exteriors
• Fill, cover or seal any cracks or holes in the exterior of structures


DIY products are not usually successful in controlling spider populations. To keep a home’s spider population under control, a pest control company should be called.
