False widow spiders (Steatodo Nobilis) are familiar pests in Irish homes and businesses. Despite only inhabiting the island for 23 years. However, in this short time span, they have thrived. Becoming one of the most common spiders in Ireland. Especially along the east coast. In fact, they are now the most common urban spider in Dublin. False widows have received a lot of publicity in recent years. And as a result, many people are afraid of them. Therefore, we get a lot of customers calling asking about them. This is why we decided to discuss this spider in today’s blog post.
False Widow Spiders Appearance
False widows have brown bulbous abdomens with cream-coloured markings similar to the shape of a skull. And their legs are reddish-brown. Females are typically larger than males by roughly 3mm. Females grow anywhere between 10 to 14mm. While males range between 7 to 11mm.
Lifespan and Reproduction
False widows have a lifespan of up to 5 years. And unlike native spiders, they are active year-round. As a result of being cold-tolerant. The average female produces over 1,000 babies annually. After mating, spider eggs grow in egg sacs. One egg sac can hold anything from 90 to 250 spider eggs. And females can produce several egg sacs per year. This information makes it clear to see how false widows have fast become so most common in Ireland.
Are they dangerous?
The media has us believe that false widows are intentionally hunting humans. However, this is not the case. Yes, false widows have venom. And they will bite if they feel threatened. However, they will not seek to bite humans. As it is a waste of venom.
In saying that though, yes their bites can be dangerous. However, the degree of injury from a bite varies from person to person. Most people experience localised pain and swelling. However, some people can have very bad reactions. And experience debilitating pain, nausea, blood pressure issues, tremors, and impaired mobility. Additionally, bacteria infection or necrosis are rare but possible side effects.
What should I do if I find a false widow on my property?
Nobody wants to share their space with a spider. But they aren’t the worst house guests to have. Especially as they control the insect population. So essentially they act as pest controllers. However, not acting on a false widow infestation is a mistake. False widows can bite. And the bites can be dangerous. Therefore, it is smart to kill any false widows on site. It is worth noting that they reproduce fast. So one spider can turn into 100 spiders overnight. Therefore, if you spot a false widow, contact a pest control company. An insecticidal spray kills off the infestation.
