These are so annoying 
I bought Stratiolaelaps scimitus and Nematodes, in combination with flytraps (and neem oil) to combat these annoying little things. It can be a hit or a miss with suppliers - you really need a good batch from a good supplier in order for it to work. This year I switched supplier and within a few weeks the ones I had inside of the house were completely gone
