#### **Mold??? ON THE SPIDER?!: Breakdown & Treatment Protocol** #### Fungal Infections on Live Spider Bodies: Overview, Causes, and Management ^d2d834 ##### Overview Fungal infections on spiders, particularly manifesting as mould growth on the cuticle, are a **‘common issue’** in captive arachnids. The cuticle, which serves as a critical barrier for both structural support and protection, can become compromised under certain environmental conditions, allowing fungal spores to colonise and spread. This growth may appear as *white or green patches* and, if left untreated, can impair the spider's health by penetrating the protective exoskeleton. ##### Causes Fungal colonisation on spider cuticles is primarily attributed to **environmental factors within the enclosure**. Elevated *moisture*, sub-optimal *ventilation*, and inadequate *sanitation* can create conditions conducive to fungal growth. Organic substrates, particularly those that retain moisture, provide ideal surfaces for fungal spores to settle and proliferate. Additionally, the *accumulation of decaying organic matter*, such as uneaten prey or plant material, can increase the likelihood of fungal establishment and subsequent infection on the cuticle. ##### Management Effective management of fungal infections on spider cuticles involves both *direct treatment* and *environmental adjustments*. Treatment typically consists of daily application of a mild antiseptic solution, such as **diluted povidone-iodine**, directly to the affected areas using a *cotton applicator.* (The author and illustrations note a q-tip as preference for ease of access) This approach can inhibit fungal growth and aid in its resolution. Preventive measures include maintaining controlled moisture levels, ensuring adequate ventilation, and employing substrates with lower moisture retention. Regular enclosure cleaning (removal of waste) is also essential in reducing the risk of fungal colonisation. ##### Conclusion These molds are *saprophytic* in nature and not to be confused with **entomopathogenic fungi** that are target specific to spiders. This just so happens to be a commonly occurring mold growing on the spiders body. We see keepers say that "*mold is not a problem*" - this stands to reason why mold should often be removed and avoided. It also presents alternative possibilities that can be worse than what we see here. In the context of *mold on your spider,* if treated early, it holds good prognosis. Other related challenges (bacterial and fungal infection, other compromises, etc) may not present as clearly or be as easily addressed. #### *Prevention is the best treatment in these cases.* ##### Source materials: (Mitchell & Tully, 2008) (Pizzi, 2012) (Lewbart et al 2022) (Kennedy 2023) Invertebrate Medicine: https://amzn.to/3SZmh2f ![[Pasted image 20241122190225.png]] ![[Pasted image 20241122190239.png]] ![[Pasted image 20241122190246.png]] ![[Pasted image 20241122190300.png]] ![[Pasted image 20241111105755.png]] ![[Pasted image 20241122190400.png]] ![[Pasted image 20241122190413.png]] ##### In addition, here is a list of adequate first-aid supplies (feel free to price check locally as needed): Corn Starch- https://amzn.to/3U3Jn92 Cyanoacrylate super glue (not gel)- https://amzn.to/4aJpKZn Betadine- https://amzn.to/3J5ABRy Syringes- https://amzn.to/3VG0uyV Sterile Saline- https://amzn.to/4cKWuDs Soft bristled paint brushes- https://amzn.to/3xkjuZA
