New research published in science journal PLoS ONE by entomologists at Ohio State University indicated that bedbugs may have boosted their natural defenses by generating higher levels of enzymes that can cleanse them of poisons.
In New York City, bedbugs now are 250 times more resistant to standard pesticides than bedbugs in Florida, researchers at the University of Massachusetts reported. This is due to changes in a gene controlling the resilience of the nerve cells targeted by the insecticide.
Ohio State University also discovered that bed bugs have evolved with thicker shells to resist insecticides.
The bad news for bed bugs is that pesticides are not necessary to eliminate the irritating blood suckers. Last year Rentokil developed an environmentally friendly product called Entotherm which not even the most armoured of bed bugs could desist.
The heat treatment eliminates all insects, including bed bugs, cockroaches or textile pests as well as moulds and pathogens without the need for large quantities of insecticides.
Entotherm kills insects by denaturing the proteins within their bodies and disrupting the waxy outside layers of the insects, causing them to dehydrate.
Insect pests such as bedbugs and cockroaches can be difficult to eliminate as they can hide in the deepest recesses. Entotherm reaches all areas of an infestation and eliminates all lifecycle stages of an insect including eggs, larvae and adults, minimising the risk ofÂ reinfestation.
Entotherm requires a single application, causing minimal disruption. Treated areas can be re-used immediately with no residual side effects. It can be used in a contained zone such as a whole room or it can target a smaller site such as a wardrobe infested with woodworm.
Chemicals are not always necessary to achieve results, and our belief is that prevention is far more effective than cure. Remember – an insect becomes a pest when it harms or destroys. Donâ€™t let it! Read our blog on how to stop the spread of bed bugs and help stop the invasion.
