My apt had flea before. We tried everything but after 1 week, they come back
.Flea's eggs are very strong.
Finally, I found the solution. http://cgi.ebay.com/Very-Effective-Safe-Flea-Trap-Light-Heat-Ca
flea trap!
Put one in every room. Fleas just can not resist it! Count the fleas trapped
every day. If the number did not increase after 2 weeks, you know they have
been all killed . So simple!
