Identification
Crevice weavers share several common characteristics that help in their identification:
- Body: Crevice weavers have a small to medium-sized body, typically ranging from 4 to 10 mm in length. Their body shape is generally elongated and oval, with a brown or gray coloration.
- Legs: They have eight long and slender legs, which are covered in fine hairs. The leg span of crevice weavers can vary depending on the species.
- Web: Crevice weavers construct flat, irregular, sheet-like webs with funnel-shaped retreats at one end. These webs are commonly found in crevices, cracks, and hidden areas of buildings and outdoor structures.
Behavior
Crevice weavers are nocturnal spiders that primarily reside in concealed spaces, such as wall voids, rock crevices, and tree bark. They are not aggressive and tend to retreat into their webs when disturbed. Crevice weavers are skilled hunters and capture their prey by ambushing them when they come in contact with their webs.
Crevice weavers, or Filistatidae, are spiders commonly found in various habitats. While they are generally harmless, if their presence becomes a concern, employing non-chemical methods such as physical removal and sealing entry points can help manage their populations. If needed, professional pest control services can provide effective solutions tailored to your specific situation.
Extermination Techniques
While crevice weavers are generally harmless and do not pose a significant threat to humans, their presence may cause concern in certain situations. If necessary, the following extermination techniques can be employed:
Non-Chemical Methods:
- Physical Removal: Use a vacuum cleaner or a broom to physically remove crevice weavers and their webs from the infested areas.
- Sealing Entry Points: Identify and seal any cracks, gaps, or openings in the structure to prevent spiders from entering the premises.
- Reduce Hiding Places: Declutter and eliminate potential hiding spots by organizing and cleaning the area.
Chemical Control:
- Insecticides: If needed, apply insecticides labeled for spider control to crevices, cracks, and other areas where crevice weavers are present. Follow the instructions provided by the product and exercise caution during application.
