Quck answer
Cockroaches have been able to develop resistance to many of the chemicals used to kill them, making it difficult to control their populations. While there are some new chemicals being developed, they are often expensive and can have negative effects on the environment and human health. Integrated pest management techniques, such as sanitation and physical barriers, may be a more effective long-term solution for controlling cockroaches.

A recent study has shown that cockroaches are developing cross-resistance to a variety of exterminators’ insecticides. This means that they are becoming resistant to multiple classes of insecticides at the same time. The study was carried out by Michael Scharf, a professor at Purdue University, and his team. Their work was featured in the June 2019 issue of Scientific Reports.
Since each class of insecticide works differently, exterminators often mix or switch them to combat infestations. But if cockroaches have resistance to multiple insecticides, the infestation cannot be controlled. To test their theory, Scharf and his team used apartment buildings in Indiana and Illinois that had infestations of German cockroaches as their experimental grounds.
First, they tested the roaches to see which insecticides had the lowest resistance on them. Then they rotated three different insecticides, which kept the roach population stable over six months. When they mixed two insecticides, the roach population increased. When they used just one insecticide for the entire six months, and the roaches had low resistance to that particular insecticide, they were nearly wiped out. However, if even 10 percent of the roaches had resistance to that insecticide, the population would increase “four- or six-fold in just one generation,” according to Scharf. During this test, the roaches also developed resistance to several other kinds of insecticides, even if the new generations had never been exposed to them before.
Scharf recommends using traps and vacuums to combat roaches, in addition to insecticides. Some of these methods are more expensive than using only insecticides, but if those insecticides aren’t going to control or eliminate a population, it’s just a waste of money.
Now That’s Even Worse News
Did you know that cockroaches can survive a nuclear blast? In an experiment set up by the team from MythBusters, German cockroaches were exposed to different levels of radiation. One group was exposed to levels similar to those emitted by the bomb dropped on Hiroshima for a month: 10,000 rads. Ten percent of the group was still alive.
FAQ
1. Why are cockroaches so hard to get rid of?
Cockroaches are hard to get rid of because they have developed resistance to many of the chemicals that are used to kill them. Overuse of these chemicals has also led to the development of “superbugs” that are even more resistant to treatment.
2. What are the health risks associated with cockroach infestations?
Cockroaches can carry a variety of diseases and allergens that can be harmful to humans. They have been linked to asthma, allergies, and other respiratory problems. Cockroach droppings and shed skins can also cause skin irritation and allergic reactions.
3. What are some of the most common chemical treatments for cockroach infestations?
Some of the most common chemical treatments for cockroach infestations include insecticides, baits, and sprays. However, these treatments are often ineffective against cockroaches that have developed resistance to them.
4. What are some non-chemical methods for controlling cockroach infestations?
Non-chemical methods for controlling cockroach infestations include sanitation measures such as cleaning up food and water sources, sealing cracks and crevices, and using traps and baits. However, these methods may not be effective against large infestations.
5. How can we prevent cockroach infestations in the first place?
To prevent cockroach infestations, it’s important to practice good sanitation habits such as keeping food and water sources clean and sealed, cleaning up spills and crumbs immediately, and sealing cracks and crevices around the home. Regular pest control inspections can also help to identify and prevent infestations before they become a problem.
6. How can we reduce our reliance on chemical treatments for cockroach infestations?
To reduce our reliance on chemical treatments for cockroach infestations, it’s important to use non-chemical methods such as sanitation measures, traps, and baits. Integrated pest management (IPM) programs can also help to reduce the use of chemicals by using a combination of methods to control pests.
7. What are some of the environmental impacts of chemical treatments for cockroach infestations?
Chemical treatments for cockroach infestations can have negative environmental impacts such as contaminating soil and water sources, harming beneficial insects and animals, and contributing to the development of antibiotic-resistant bacteria.
8. What are some of the economic costs associated with cockroach infestations?
Cockroach infestations can be costly for homeowners and businesses due to the need for repeated treatments and repairs to damaged property. They can also lead to lost revenue for businesses that are forced to close temporarily due to infestations.
9. What are some of the challenges associated with developing new chemical treatments for cockroaches?
Developing new chemical treatments for cockroaches is challenging because cockroaches have developed resistance to many of the chemicals that are currently used. It’s also important to consider the potential environmental and health impacts of new treatments.
10. What role do education and public awareness play in controlling cockroach infestations?
Education and public awareness can play a key role in controlling cockroach infestations by promoting good sanitation habits and identifying infestations early. They can also help to reduce the stigma associated with infestations, which can make it easier for people to seek help and treatment.
11. What are some of the long-term solutions to the problem of cockroach infestations?
Long-term solutions to the problem of cockroach infestations include developing new, more effective treatments, promoting good sanitation habits, and reducing our reliance on chemicals. It’s also important to address the underlying causes of infestations such as poverty, lack of access to housing, and inadequate sanitation infrastructure.
12. What can individuals do to help prevent the spread of cockroach infestations?
Individuals can help prevent the spread of cockroach infestations by practicing good sanitation habits, sealing cracks and crevices around their homes, and reporting infestations to their local pest control providers. They can also help to reduce their reliance on chemicals by using non-chemical methods such as traps and baits.
