What is Delusory Parasitosis and how does it relate to pest control?
TL;DR — Quick Answer
Delusory Parasitosis (Ekbom Syndrome) is the firm belief your body is infested with invisible parasites, causing real crawling/biting sensations without physical proof. It links to pest control because affected people often call us first.
Worms of the Mind: Mental Health Awareness & Wellbeing
“Worms of the mind” is a metaphor for negative thoughts, worries or stressors that can slowly affect our mental wellbeing if ignored.
Have you ever felt something crawling or biting your skin, only to find nothing there? For most people this passes quickly — but for some, this feeling never stops.

What exactly is Delusory Parasitosis?
Delusory Parasitosis — also called Ekbom Syndrome — is a condition where a person is fully convinced their body is infested with invisible bugs, mites, worms or other parasites. The sensation feels completely real to them, even when no physical evidence exists.
What does it feel like and how do people respond?
Sufferers feel constant crawling, creeping or biting sensations under or on the skin. To find the “parasites,” some may harm themselves using:
- Fingernails
- Scissors
- Tweezers
- Knives
Research published in the Australian Journal of General Practice notes that over 60% of people with this condition first contact pest controllers, vets or dermatologists before seeing a mental health professional.
When you suspect biting pests but see no evidence, call us on 1800 819 189 — we help you rule out pests safely.
What causes these sensations?
Triggers can be physical, mental or environmental. Medical studies list these common causes:
- High stress or anxiety
- Prescription or illicit drug reactions
- Allergies or extreme dry skin
- Mechanical skin irritation
- Skin cancers or vitamin/protein deficiencies
- Diabetes or thyroid issues
- Cerebrovascular disease
According to NSW Health, around 30% of cases link to an underlying medical condition that needs treatment — not pest control.

|---|---|---|
| Visible pests/signs | Yes — live bugs, eggs, droppings | No — nothing found despite repeated checks |

| Timing | Linked to activity or location | Constant — everywhere you go |
| Response to treatment | Improves after proper control | No change — symptoms persist |
Frequently Asked Questions
Is Delusory Parasitosis a mental illness?
It can be linked to mental health conditions, but it also often stems from physical illness, medication or sensory issues. It requires assessment by a doctor or specialist.
Can pest control fix this?
Only if actual pests are found. If no pests exist, spraying will not help — and may delay needed medical care.
Will you dismiss my concerns if you find no pests?
Never. We listen, investigate fully and support you to get the right help.
