Why Do Bed Bugs Reoccur Even After a Treatment?

Some of you would have faced the challenge of having bed bugs in your home over and over again. It is like reliving a horrible nightmare, not knowing when and how they will come back. While you may have done some DIY pest control such as using a bed bug spray, or even called up a professional pest control company in Singapore, why do bed bugs reoccur even after a treatment?

Bed bugs are small and very tiny


An adult female bed bug is only about 5 to 6mm in length! This makes finding and locating them difficult. The elimination process could be not thorough enough, leaving behind bed bug eggs.  Particularly at hard to reach spaces or blind spots in your home, it makes it almost impossible to spot them all, and these left-over traces might reproduce and manifest over time.

Bed bug is a cross infestation pest

Regular travelling increases your risk of bed bugs when these ‘hitchhikers’ are easily transported through clothing and suitcases. From people to people, location to location, the risk of passing on these bugs to your home may be high.

Ineffective DIY pest control

Bed bug sprays or off-the-shelve deterrent sachets does not help in eliminating bed bugs easily. Many of these bugs are not killed and it is not a solution to resolve root source of the problem.

What to expect during a bed bug treatment?

There are many types of bed bug treatment that differs in terms of choice of active ingredient used, application mode (such as residual spraying or steam treatment) and combination of services. During a bed bug control, site survey and risk assessment is necessary to ensure adequate pest control coverage while eliminating safety risks. To allow proper elimination of the bed bugs in all life stages, the recommended frequency is usually three times before completing the service with inspection and monitoring.

Factors affecting the efficacy of bed bug treatments

Treatment frequencies, coverage area, chemical contribution and quality will also impact the efficacy and effectiveness of controlling bed bug challenge. For instance, bed bug treatment is best recommended to carry 3 times with follow up inspections. To ensure both adult and eggs are eliminated, both residual spray and steam treatment is recommended. While some treatments appear to be very affordable, we should also be mindful on the quality of chemical used should not compromise over efficacy.
