For many home owners living in the town of Grafton, Massachusetts, a newly discovered poisonous spider can cause alarm and confusion. The fear of such a venomous arachnid is justified, as bites from these spiders can potentially be deadly. Many are left wondering how to manage the potential infestation in their home, and whether additional pest control services may be of help. To address these concerns and more, we provide answers to the most frequently asked questions (FAQs) around Grafton’s new poisonous spider.

What Is the Newly Discovered Poisonous Spider?

The recently discovered poisonous spider in Grafton, Massachusetts is a species of widow spiders known as the false black widow. These dimorphic spider species look and behave much like the common black widow, with two exceptions. First, false black widows only date back to the Middle Ages, whereas the common black widow dates back to Ancient Greece. Second, false black widows are brown with lighter markings rather than black with red markings.

Where Are False Black Widows Found?

False black widows have spread throughout the northeastern United States and are found as far south as Florida. Though they can be found in a variety of habitats, they are particularly common in wooded areas and dense vegetation and have been known to build webs in doorways, windows, and sheds. They have also been found in abandoned buildings and areas near compost piles and plant debris.

What Risks Do False Black Widows Pose?

The false black widow spider is the most venomous of all the widow spiders. While their venom is not as toxic as the common black widow, false black widow bites can still cause serious pain and lead to complications. The risk is higher for children, elderly persons, and those with compromised immune systems. In addition, false black widows have been known to bite when threatened or disturbed and have been known to get into homes through open windows and doors.

What Are the Symptoms of a False Black Widow Bite?

Symptoms of a false black widow bite will usually surface within one to two hours after being bitten and can include pain and redness near the affected area, muscle cramping, nausea and vomiting, difficulty breathing, and an elevated heart rate. In some cases, the bite may only cause red marks or a rash, but anyone who has been bitten should seek medical attention.

Are There Ways of Preventing a False Black Widow Infestation?

There are several steps that homeowners in Grafton can take to help prevent an infestation of false black widow spiders. These include sealing openings around windows and doors, using caulk to fill any crevices or holes outside the home, getting rid of clutter or potential hiding places, and reducing areas of excess moisture or dampness. Additionally, it may be beneficial to reach out to a pest control specialist for help in identifying and eliminating sources of infestation.

What Is the Best Way to Eliminate a False Black Widow Infestation?

Eliminating a false black widow infestation is not an easy task. Since spiders are quick to hide and reproduce rapidly, it is best to hire a pest control specialist with experience managing false black widows and other pests. Experienced technicians can use an integrated pest management approach which involves monitoring, prevention, and exclusion of the spiders in a safe and effective manner.
