I've had a pest control man come to my apartment, because of fles all through my place even my bedding, but I still feel them in my bed and shoes, I look to see so I can kill them , but I can't see them . MPlease help thank you . Am at mt wittsa end, I don't know what else to do

If you no longer see them, have you considered the possibility that something else is causing what you feel? The part about 'in your shoes' tends to make one think about a reaction to something. Do you still have the record of what chemicals were used? If so, you might want to see a dermatologist and take that list with you.

Something else to think about: In the Northern hemisphere it's the height of summer with humidity and temperature at the extreme ends of the scale. That's a good time for mildews and fungus to grow. A dose of Tinea fungus can feel like insect bites and itch horribly. Again, a dermatologist can diagnose that and prescribe medications and ointments to cure it.

Of course, it can take two or three times to get rid of some... and is there a reason, they got in house to start with... did that get solved?

But sometimes, we still "feel" it after gone, because of our mind...

Wayne, try using a sticky lint brush to catch them on your clothes and on sheets.
Try smacking your shoes in the toilet bowl and see what comes out.
