I woke up one day with three bed bug bites on my back. Honestly, I thought they were a skin problem, and went away on a week-long trip. When I got back, I found what looked like a bed bug by the shower drain. I killed it, and the next morning I found that I had gotten two new bites in the night. Another day later, I had three bites on my arm. I also killed another bedbug in the bathroom. I did my research, and bought this spray as well as DE dust. After applying the dust to the four legs of my bed, along the floor, and making a dust barrier at all the doorways, I then thoroughly sprayed the mattress with this Harris spray. One 16 oz bottle was just enough to spray the whole mattress top and under, and also the bedframe beneath the mattress. I did not have enough in the one bottle to spray the whole room. This stuff goes quickly. In any case, I was bedbug bite free for a good four weeks after that. And then one dawn, I woke up to a bedbug sneakily crawling away from me on the pillow, which I promptly squished to death. Too late though, because I found a bite on my hand. I immediately went to the drug store and bought another bedbug spray (ortho brand) and sprayed the whole mattress again. I also ordered this from Amazon again, and when it arrived in 3 days, I used it on top of the ortho one. That was 8 days ago, and I have not found another bedbug or had another bite. So, I concluded that this spray will kill the bugs it can reach, but that the residual kill effect might be only in effect a couple of weeks. After that, it looks like you need to reapply. I plan to order more cans of this and the ortho (which also seemed very effective), and alternate spraying my bed and surrounding floor every 2-3 weeks for at least a few months. Will provide updates as to how that goes. - 12.28.2018 Update 3.14.2019 - bedbug free! Haven’t had a bed bug bite since December 2018, so I conclud that they’re gone. I am gonna keep buying the sprays to use regularly on the carpet of the hallway outside my apartment, especially near my door, because those initial bugs must have come from a neighbor, so I figure the best preventive is to kill them before they reach my apartment. Otherwise, I am breathing a big sigh of relief. Read more

I recently purchased this product twice because I ran out and needed more. This spray has worked well in eradicating a bedbug infestation brought home from an out of state hotel. Upon removing the cap from the second can I bought, I had to use a wrench to get it off, it was so tightly attached. In the process of removal, the cap snapped and broke off the stem of the spray nozzle. I contacted a customer consultant at Harris to request a replacement can, which she did send to me. I am impressed with the service this company provides since this problem was obviously a manufacturing issue. Read more
