Bedbugs are small (up to about 5mm), brown and flat bodied parasitic insects found on mattresses and beds. These creatures feed off the blood of the occupier and can cause a whole Sydney household discomfort as they scratch themselves to sleep each night. Their bites are small and often in a trail, spread out across the whole body and become red and very itchy. Occasionally even causing infections that need to be treated with antibiotics. These pests have been problematic in every society for centuries, but scientists and developers have yet to commercialise an easy way to get rid of them. Lucky for you, Masters Pest Control Sydney have an effective bed bug treatment plan to combat the nasty pests.
Bedbugs often travel via people’s personal belongings, trapped within packed clothes until they arrive in a hotel or other residency. It is very important to check for them when arriving in a new living space, but do not forget to check for the creatures regularly within your own home. They should be checked for between the mattress and the base of the bed and along the linings of the mattress. They also particularly like the deep creases between sofa cushions. In infested furniture, edges are lined with adult bugs. There may also be trails of tiny white eggs and dark dots of feces and blood. You should avoid second-hand mattresses if possible as a preventative measure.
Bedbugs can survive up to a year without a feed, making them even harder to get rid of. Healthdirect suggests steaming, vacuuming, washing clothes in hot water and drying them in a hot dryer to get rid of bed bugs once they have been detected. Bedbugs are quite resilient and it may take several repeats to truly get rid of just a small amount of them. There are companies that offer professional chemical pest control treatment for bedbugs available in Sydney, but there have been recent concerns that these treatments are becoming less effective over time. The Sydney Morning Herald reports that studies conducted in 2014 in the Department of Medical Entomology, Westmead Hospital as well as University of Sydney, have found the common bedbug of NSW to be surprisingly resistant to insecticides. The research showed that the Sydney strain of bedbugs needed 250 times as much bendiocarb, 370 000 times as much deltamethrin or 1235 million times as much of the insecticide permethrin to be killed as a strain that was commonly susceptible to insecticides. Cameron Webb, a medical entomologist with University of Sydney and NSW Health Pathology, said that there had been “evidence of a resurgence of bedbugs over the last decade” in Sydney. The experiments on Sydney strains provided explanation for this.
These parasites have a long history of survival, narrowly escaping some technological advancements but escaping nonetheless. The use of the insecticide DDT after World War II almost wiped out the species, however the few strains that survived did so steadily until they rose in numbers dramatically once again. Westmead Children’s Hospital reporting a 400 per cent rise in bedbug cases from 2000 to 2004, leading up to the discovery that they were pesticide resilient in the 2014 case studies.
Possible developments to fight back against the resistance have been investigated since, with the help of credible researchers like Canadian scientist Dr Regine Gries. Dr Gries and her biologist husband Gerhard Gries announced with Simon Fraser University the invention of a trap using pheromones as bait in January 2015, but the fix is yet to come into commercial production. Simon Fraser University announced on their website in 2016 that Scotts Canada had become the industrial sponsor of their research chair, bringing their invention closer to commercialisation. Surrounding this field of development is the continued renewal of methods to eliminate other parasitic nuisances such as head-lice and mosquitoes, which have also been witnessed evolving to become more resistant to certain insecticides over time. For example, scientists at the university’s Centre for Animal Biotechnology have recently developed a lotion called Xeglyze to combat the recently resistant lice, something with properties that could potentially be useful later on in defending Sydneysiders’ beds from the increasingly resilient bedbugs.
The dense population of Sydney accommodates to the fast spread of stronger strains of bedbugs residing within the city. Sydneysiders should be checking their mattresses every few months and checking luggage and hotel beds upon arrival to ensure they do not wake up with lines of itchy spots across their skin. Though new inventions are coming through, Sydneysiders are yet to receive them. Those with infestations may currently have to resort to hours of manual labour or simply replace their mattresses in order to rid themselves of this burden.
