Anyone in the Newtown area who has experienced a bite from an agrarian sac spider is unlikely to forget it. These bites are not only extremely painful but, in rare cases, can cause tissue decay at the wound site.
While agrarian sac spiders are beneficial outdoors due to their diet of pest insects, their presence indoors is a different story. Once inside, it’s crucial to identify and seal entry points to prevent further infestations. If you're unsure where these spiders might be entering your home or need help keeping them out for good, contacting a licensed pest control professional is your best option.
At Newtown Termite & Pest Control, Inc., we specialize in identifying vulnerabilities in your home and sealing them to keep spiders and other pests outside. Let us help you reclaim your space.
These spiders stand out due to their light yellow or cream-colored bodies, with dark brown chelicerae and tarsi. They feature a distinctive dorsal stripe on their abdomen and elongated front legs. Adult females measure 5–10 mm, with males being slightly smaller.
Agrarian sac spiders are nocturnal hunters and use their web-spinning abilities to create tubular sleeping sacs. Indoors, these sacs are often found in cluttered or dark spaces like attics, basements, storage rooms, garages, and sheds. Outdoors, they may place their sacs in leaf litter or plants.
These spiders are active hunters that capture insects and other arachnids rather than trapping them in webs. Outside, they are natural pest controllers, consuming species that can harm crops, flowers, and gardens.
Agrarian sac spiders are not destructive, but their painful bites give them an aggressive reputation. Bites usually occur during outdoor work or if the spider hides in shoes or clothing. While their venom rarely causes serious harm, bites can lead to allergic reactions, infections, or tissue damage in rare cases. Seek medical attention if symptoms worsen.
The vast majority of spiders transmit venom when they bite, and agrarian sac spiders are no exception. This venom is most effective on insects and arachnids. In most cases, too little venom is transferred from the spider to a human to cause problems.
The most common reactions to a bite from an agrarian sac spider include a red welt that might be itchy for a day or two. Rarely, people have experienced tissue damage at the bite site. If a spider bite seems slow to heal or is causing complications, seek medical advice.
Additionally, any spider bite can become infected, especially if scratched too aggressively. Some people may even have allergic reactions, causing dizziness, headaches, or nausea. A doctor’s visit may be necessary to address these issues.
Take these steps to minimize the risk of an agrarian sac spider infestation:
Spider treatment involves the detection and elimination of all webs. If this is not done, the spiders are likely to re-infest the structure. Generally, DIY methods are not effective for complete spider elimination. Professional pest control is recommended to safely and effectively treat infestations.
