One way to find out if bed bug treatment really works is to place traps on each leg of the bed to control how many of the creatures are caught each day. If you notice that the number is decreasing, it is a sign of your improvement. This means that the treatment is working. How do I know if a bedbug treatment has been successful? (pdf).
Check the places where you found them before and look closely to see if any are still moving. If you don't see movement, it could mean that the treatment was 100% successful, but don't assume it. Even so, it is wise to check every day for the next few days to make sure they have been completely eradicated. The simple answer is to wait three weeks to see if there is any bedbug activity in your home.
If you don't find any signs of the bugs in that period of time, it's very likely that the creatures are gone. This depends on the type of treatment you have chosen. If you paid for heat treatment, you should notice an immediate and drastic improvement. Getting rid of bedbugs completely can take weeks or months, depending on the nature and extent of the infestation.
If heat treatment is used to control the infestation, one treatment is more likely to be sufficient, but re-treatment may be necessary if there are some areas that were not fully treated or if bed bugs were reintroduced. A bedbug can smell that pesticides or other “nasty” have been sprayed in their house, so they naturally want to find another place to live. These traps are designed to be placed under the legs of beds, chairs and sofas to control bed bug infestations. But even after the most thorough treatment, you may have to wait weeks for all bed bugs to die.
You can also start your own bed bug treatment, regardless of whether your exterminator managed to get rid of all of them or not. It's awful to look at it, or even think about it, but every dead bug means one less bug that will bite you in the middle of the night. Any surviving bed bugs on the mattress or box spring will not be able to escape from the cover or the bite. Bed bug nymphs that hatch after treatment will be able to reproduce and grow unless a second treatment is performed to kill them.
The Michigan State University Extension article, Preparing Your Home for Bed Bug Treatment, outlines the steps you need to take. Bed bugs lay their eggs in hidden crevices and crevices, which usually means furniture, but it can mean stacks of clean towels or in the back of your closet. If you recently sprayed against bedbugs or if an exterminator visited your home, you may be wondering if the treatment was successful. After carrying out physical repairs, cleaning and treatment, it is important to monitor for surviving bedbugs.
Take it as a good sign, because it means more bed bugs come into contact with your spray or dust. That's why it can be hard to tell if the pests have disappeared for good after a bedbug treatment you own. Of course, if they realize what appear to be bedbug bites, they should immediately take steps to alleviate the problem.
