Why do I feel itchy every time I go under my deck?
I have a large space under our deck that is enclosed and have been turning into a sort of shed. Every time I go in there though I'm super itchy all over like something has been biting me. I don't see any insects though. However I am bad at noticing things like bugs.
It's probably termites! Their nests tend to grow a mold that causes allergic reactions in lots of people. Exactly the sort of thing that would make you itchy.
Do you store any chemicals or new building materials in there whatsoever?
Chlorine does this to my feet when I open the container to add more to the pool. It's heavier than air, so wafts out of the container then "spills" over onto my shoes, causing a reaction with the moisture on my skin. Much healthy :))
Have you noticed any rash or other marks on your skin where you feel itchy? Bumps, redness, dry patches, etc. Different irritants can have different reactions on the skin, so that may help you identify the cause.
Very minimal to cover basic admin and licensing, venue costs are low due to the under-deck siting. Accidentally setting up a Mental Association can be very rewarding.
Either an allergic reaction to something you only eat for breakfast, or dust mite allergy (sneezing to get rid of all the allergens you breathed in from your mattress), or photic sneeze reflex from the morning sun?
If you eliminate allergy, toxic substances, bugs and trauma then only possible explanation left is that it's haunted. Sometimes it's the irrational that is left to explain reality.
For bugs you can try glue trap and then check if something has been cought.
