From the first day I found this site I started to be on the defensive on the "bugs" I vacuumed every day in the places where I spent time. I sprayed with a mixture of white vinegar and water on everything. Then I ordered Tweet from safe solutions, and we mix that in a spray tank and spray all carpets and throw rugs once a month. In between I use my spray bottle with either the vinegar or the tweet mixture, alternating it. I also used the DE when I got it. Sprninkled it all over the place. Now I think it helped but maybe it was a combo of all the things. I don't get bites anywhere in my house.
I do keep up the spraying and vacuuming regularly though. I even spray my bathroom floor until it is wet with the tweet or vinegar. (it is tile) I let it dry on there. I spray the walls too!
I know this sounds like a lot of work and it is, but I feel it is worth it to keep everyone that comes into my house as safe as I can. About once a month I take a brush called a webster and do my ceilings and fans etc.
I clean my kitchen daily as throughly as possible also. Wash all the counters and vacuum the hardwood. Wipe down the cabinet fronts etc.
LOL! I told you all that I was a clean freak, I was even before I got the morgs, just more so now.
I hope this helped at least a little. It is a big job! Do what you can and make sure you take even better care of yourself. That is what counts the most in my book.
