How to Get Rid of False Widow Spiders

July 5, 2023

Due to their increasing presence, false widow spiders have become a concern in the UK. Understanding these spiders and addressing infestations is crucial to ensure a safe living environment. This article will explore effective methods for eliminating false widow spiders and implementing pest control measures.

Identifying False Widow Spiders

Characteristics and Appearance

False widow spiders, including the noble false widow, share similarities with the venomous black widow spiders. They have a dark brown or black body with distinctive markings, such as cream-coloured spots or markings on their abdomens. Their bodies, with shiny exteriors, are typically around 10 to 14 millimetres long.

False Widow Spider Bites

While false widow spiders are venomous, their bites are rarely serious or life-threatening. The severity of the bite depends on factors such as the individual's sensitivity and the location of the bite. Symptoms may include redness, swelling, pain, and in rare cases, more severe systemic reactions. It's important to seek medical attention if you suspect a false widow spider bite.

Assessing False Widow Spider Infestations

To effectively address false widow spider infestations, it's essential to identify signs of their presence and assess the extent of the infestation. Look for spider webs, typically irregular in shape, located in undisturbed areas such as sheds, garages, or corners of rooms. Inspect hidden spaces and dark crevices where false widow spiders tend to build their webs and lay eggs.

Methods to Get Rid of False Widow Spiders

To effectively eliminate false widow spiders from your home, it's important to employ various methods targeting their behaviour, habitat, and population. Here are detailed approaches to getting rid of false widow spiders:

Prevention and Exclusion

Prevention is key to avoiding false widow spider infestations. Start by sealing off potential entry points such as cracks, gaps, and openings in doors, windows, and walls. Ensure that window screens are intact and fit tightly. Install door sweeps to block their entry. By denying them access, you can significantly reduce the chances of false widow spiders establishing themselves inside your home.

Natural Repellents and Deterrents

Utilize natural repellents to deter false widow spiders from entering your living spaces. Certain scents and substances are known to repel spiders. Peppermint oil, vinegar, citrus peels, or a mixture of water and essential oils can be sprayed around entry points, corners, and other areas prone to spider activity. These natural remedies can help create an unfavourable environment and discourage false widow spiders from settling in.

Proper Cleaning and Maintenance

Regular cleaning and maintenance are vital in managing false widow spider populations. Vacuum and sweep your home regularly, paying special attention to corners, crevices, and other secluded areas where spiders may hide. Remove any webs you come across and dispose of them properly. By eliminating existing webs, you disrupt their habitat and discourage their presence.

Additionally, reducing clutter and maintaining cleanliness in storage areas, attics, basements, and garages minimizes potential hiding spots for false widow spiders. Decluttering also eliminates potential food sources and nesting materials, making your home less appealing to these pests.

Chemical Control

In cases of severe infestations or persistent false widow spider problems, chemical control methods may be necessary. It is crucial to exercise caution when using chemical pesticides and strictly follow the instructions provided by the manufacturer. Consider consulting with professional pest control services to safely and effectively apply insecticides.

When applying insecticides, focus on areas where spiders are commonly found, such as dark corners, crevices, and cracks. Ensure proper ventilation during and after treatment, and keep children and pets away from treated areas until it is safe to re-enter.

Professional Pest Control

For extensive or recurring false widow spider infestations, it is advisable to seek the expertise of professional pest control services. These professionals possess the knowledge, experience, and specialized tools to manage and eliminate false widow spiders from your home effectively. They can conduct a thorough inspection, identify the source of the infestation, and develop a tailored treatment plan to address the problem at its root.

Professional pest control experts may utilize a combination of techniques, such as targeted insecticide applications, web removal, and long-term prevention strategies to eliminate and prevent false widow spiders.

Implementing these comprehensive methods can significantly reduce false widow spider populations and create a safer and more comfortable living environment. Remember to choose the methods that best suit your situation and prioritize the safety of yourself and your household throughout the process.

Spotting and Dealing with False Widow Spiders

When encountering a false widow spider, it's important to exercise caution. If you find one inside your home, safely capture it using a glass and a piece of paper and release it outdoors. Avoid handling false widow spiders directly to minimize the risk of bites.


False widow spiders can be a cause for concern in the UK, but you can effectively manage and control their presence with proper knowledge and proactive measures. By identifying false widow spiders, assessing infestations, implementing prevention methods, and seeking professional help, you can ensure a pest-free environment and maintain peace of mind in your home. Remember, taking preventive measures is key to managing false widow spider infestations. Regularly inspect your property for signs of webs, nests, or spider activity. Address any issues promptly to prevent the infestation from spreading.
