I'm a renter on the 17th floor. I don't seem to have a big infestation (saw less than 15, dead and alive), might have been that I discovered them early in the cycle? They were nesting in the 4 corners of my bedframe just under the mattress but didn't take over the mattress at all. Might be the fact that I have an IKEA bedframe with slats and a foam mattress which is less inviting than a box spring set.
Got bitten twice in the left leg about 2 months ago before I realized what was going on. S
prayed the entire place several times with Raid (the formula that kills bedbugs) and has never been bitten again. Some bugs did come out to die. Cleaned my bedframe and there has been no trace of feacal matter since then. Know that they are still probably in the apartment but it seems to be under control.
Looks like they came from the unit next door since I've seen 4 live ones at different times at almost the exact same spot on the wall I share with the neighboring unit. Seemed like they were climbing up from the base board.
Someone must have reported the problem and Management hired pest control who came earlier this week to treat the apartment. Only one bug came out to die after the treatment. Hopefully it's a good sign that I don't have a big problem left. I will keep spraying on my own and considering getting a handheld steam cleaner in case new bugs come in from neighboring units.
