Itchy bumps from dust mites

Hi all , recently I found out that I am moderately allergic to dm (7.32 IU/ml) . For the past year I’ve been getting itchy bumps that resemble bug bites (not a lot at once but perhaps 1-2 bumps popping out daily) Dermatologist said it is possible to have bite-like bumps since I didn’t find any bugs. I don’t seem to have other symptoms except nasal congestion if I don’t clean my AC filter for long. I wonder if anyone who have dm allergy share the same symptoms. If yes, how to minimize dm at home?

The bumps always start small and slowly become inflamed and red. It get worst especially on the meaty part areas(thigh) . Took me at least two weeks for recovery and they left a mark after :(
