When compared to other pests found in homes and offices throughout the Bristol area, spiders seem relatively harmless. They do not sting, rarely bite and do not spread illnesses. Nonetheless, they can become a nuisance when there are too many of them, and this is especially true when they come indoors.
Spiders do not belong inside structures. In the garden, they may be controlling other pests, but they cause a mess indoors. Moreover, when there are too many of them, a larger pest problem may be ongoing.
Broad-faced sac spiders, daddy longlegs spiders, grass spiders, common house spiders and wolf spiders are all found around Bristol.
Spiders are not insects. They are arachnids, so one of their most noticeable characteristics is their eight legs. The majority of spiders have bodies made up of two segments. These are the abdomen and a thorax and head that are conjoined.
Adult female broad-faced sac spiders may be as big as 10 millimeters while males are half of this length. Their abdomens are gray or yellow, but the rest of their body is brown. With a dark dorsal stripe, they are fairly easy to identify. Also, this spider has thicker, darker front legs than rear legs.
Their lengthy, spindly legs make the daddy longlegs appear much larger than it is. With their legs, they may measure as much as 50 millimeters. However, their body is only approximately two to 10 millimeters long. Their bodies usually are brown, gray or black.
Grass spiders are smaller than daddy longlegs with adult females being about 20 millimeters long. Males are nearly the same size. Yellow and brown stripes on their carapace make it easier for these spiders to remain unseen by predators.
Common house spiders are compact with females only growing to about eight millimeters. Most males are only half this length. Their bodies are distinctive thanks to the chevron-shaped markings on their bodies and their striped legs. Brown and gray stripes are common.
Wolf spiders appear bulky because of their thick covering of brown, gray or black hair. This dull coloring makes it easier for the wolf spider to hide in dark areas. The largest members of the species may be 35 millimeters long.
Having a few spiders in a garden is considered a beneficial thing. This is because this species exclusively eat insects, other arachnids and other tiny pests. Accordingly, detrimental species like flies and mosquitoes may be controlled thanks to the presence of spiders.
Many web-spinning spiders live in elevated locations where flying insects are more likely to be trapped. Trees and tall shrubs provide likely nest-building locations. Spiders also use the space between branches and exterior walls for placing a web. Areas with good lighting are generally preferred, as the light may attract prey. This is why indoor and outdoor lighting fixtures frequently are adorned with spider webs. Windows and doorways make other likely spots for a web.
Ground-dwelling spiders have much more luck catching walking insects. This is why they build webs at ground level, often over grass or exposed soil.
Still other spiders, such as the wolf spider, do not spin webs. They use underground burrows as nests, and they hide in dark areas where they wait for prey.
PROBLEMS WITH SPIDERS
Generally considered a beneficial presence when they are restricted to gardens and are only seen in ordinary numbers, spiders become a nuisance when people are forced to routinely clean up spider webs from building interiors. Moreover, no one enjoys the idea that a spider might drop onto them from above when they are in the safety of their own home.
The ferocious appearance of the wolf spider is another issue. Some people are inordinately frightened by the sight of these rather large and hairy creatures. Although outright confrontations are rare, bites do happen when the wolf spider hides in things like shoes and gloves.
Spiders may be active during both the day and night. They are fairly industrious, particularly when they need a new web. This is because the web serves as home and a trap for food. The success of the web is critical to the spider's survival. Accordingly, they may build several webs to test their ability to catch prey before settling on an ideal spot.
Spiders are likely to be most active during the dusk hours as this is when more insects venture out. Many of these insects are attracted to light, so spiders frequently build webs that are close to artificial light sources. Whenever an insect gets caught in their web, the spider goes into action to ensure that it cannot escape.
Not all spiders are web spinners. The wolf spider is one of these exceptions. Accordingly, they must have some other means of getting a meal. Wolf spiders prefer to wait in dark, cluttered spots so that they can quickly pounce on insects as they walk by.
The spiders that are commonly found in Bristol are not known for transmitting any kind of illness. Moreover, their bites are rarely any cause for concern. The wolf spider is capable of delivering the most painful bite, but even this typically elicits a temporary and relatively mild reaction.
SIGNS OF A SPIDER INFESTATION
The following signs may indicate a spider control problem:
• Walking through spider webs each morning when leaving the house
• Having to constantly take down spider webs inside buildings
• Receiving more than one spider bite
Precautions to help prevent spider issues include:
• Do not allow trees, shrubs, plants or lawns to become overgrown
• Eliminate holes and cracks in building exteriors to help keep pests outdoors
• Have regular pest control treatments performed on the property
• Use a power washer once or twice a year to clean exteriors
• Routinely use a broom to eliminate spider webs from outdoor surfaces
• Dust and vacuum indoors to get rid of spiders and their webs
• Make certain that screens on windows and doors do not have holes
When spiders invade any Bristol home or office, it is always wise to consult a professional exterminator. The technician will conduct a thorough inspection to detect the presence of any and all pests, which may include destructive insects like carpenter ants and termites. By taking care of any underlying pest issues, it is possible to reduce the spider population as well.
Do-it-yourself pest control methods rarely are as effective as the services of a spider control technician. An experienced exterminator should be consulted to deal with the problem in the safest and most efficient manner possible.
Safeguard Pest Control will use a variety of treatments including dusts, gels, and specialized products to eliminate spiders in your home including attics, wall voids, and cracks and crevices.
Our technicians use environmentally safe products to repel spiders and discourage breeding and population growth.
