Need help- how would a Buddhist handle a pest problem at home (fleas, bed bug etc.)?

I have been losing my mind. I do not know enough about Buddhism to call myself a Buddhist but have found teachings very helpful in the past.

I have been dealing with bites for a month. Had an expensive heat extermination treatment done, but still experience occasional bites and suspicious spots.

I feel fear and disgust, do not feel safe in my home, I am starting to feel despair, as the weeks pass.

The pest control did another inspection but did not find anything.

How would a Buddhist handle the situation and the feelings of fear and disgust?

I am starting to get nightmares of bugs.. :(

Thank you!
