Seeing a cockroach scurrying across the floor or hiding inside a closet door, it's intriguing to purchase total release foggers (TRF) — or “bug bombs” — in an attempt to free itself from multi-legged insects. But the chemicals in these products have every chance to create more harm than utility, especially when it comes to human well-being, according to a new study.

A study conducted by researchers at the North Carolina state Institute and recently published in BMC public Health magazine has demonstrated that bombs with blunders are considered an inefficient method of freeing your home from cockroaches and expose people and family animals to the risk of pesticides. Scientists have noticed, in fact, that the " toxic residue “of these goods is usually located on the countertops and floors," cockroaches are usually avoided, but that are widely used by people and domestic animals, " according to the news release of the Institute, detailing the study.

“The basic value of insecticides in these homes have value, due to the fact that the actual inhabitants with moderate and difficult infestation of cockroaches, most likely, will be to apply insecticide in order to try to remove cockroaches," said Zachary, Debris, municipal postdoctorates the NC prospector and the main Creator of the study, explained in a statement.

“However, the most embarrassing thing is that these tampons were collected from the middle of the floors and kitchen planes, spaces where cockroaches usually do not gather," he explained.

In order to come to this conclusion, the scientists tested 4 different fogs in 20 dwellings, which were listed as “infected cockroaches".” They took samples from all sorts of planes before the introduction of beetle bombs, and then immediately after their launch. They returned to the proper direction a few months in order to arrest more samples. Populations of a roach in dwellings were still controlled in the direction of this time “to estimate efficiency of TRFs", - they wrote.

Scientists have tested only gel lures in 10 dwellings in order to compare the effectiveness of these products.

Conclusion? “TRFs did not work to reduce population of cockroaches, while similar in cost gel baits caused an important decrease populations of cockroaches," say the scientists, noting in fact that the bombs with insects “have led to important deposits of pesticides throughout the kitchen.”

According to the study, the degree of pesticide residues still it was higher than before the bombs, the bugs were blown up, with the result that the average degree of residues of insecticides has increased “600-one " on the kitchen surfaces, walls, floors and in other areas only through a certain number of hours subsequently release chemical drugs.

Meanwhile, the gel baits were significantly more effective, and by the time the study was completed, they had safely killed the roach population in the 10 dwellings where they were tested. Why? According to the opinion of the surveyors, these products may be more precisely applied in the spaces where these insects are hidden. Pesticides found in foggers, relatively, accumulates in the spaces of roach, less likely to wander.

"Insect bombs don't kill cockroaches; they put pesticides in spaces where there are no cockroaches; they don't put pesticides in spaces where there are cockroaches, and they increase the degree of pesticides in the house," Devris said. “In the cost-benefit analysis, you get all the costs and virtually no benefits.”
