How Insects Become Resistant to Insecticides

Unfortunately, insects are liable to become immune to the effects of the insecticides that we use against them. When this occurs, it’s much more difficult to get rid of a pest problem, because you can’t use tried and true methods like sprays and traps. Sometimes it’s essential to switch up and use alternative methods to rid your home or business of pests. The bottom line is that you don’t want to live with cockroaches, ants, termites or other bugs crawling all over your home.

That’s why it’s always best to call in the experts in pest management in Rochester, NH. They know which insects have become resistant to which insecticides. They also know all the different methods for ridding your home of pests. Let’s take a closer look at insect resistance and what you can do about it.

What’s the root cause of resistance?

As you’ve probably noticed, the pests invading your home are surprisingly resilient. You’ve tried and tried to get rid of them, but they just keep coming back. Initially, when we try to control insect populations with insecticides, a number of bugs die, but a small number will have exposure to the poison but continue living.

Then, these bugs reproduce and pass the trait onto their offspring. This is a classic evolutionary tactic, and the bug’s physical makeup—such as a thicker shell—or metabolism will shift toward resistance to the insecticide. The same phenomenon happens with antibiotics given to humans and animals. The virus the antibiotic is supposed to treat may change and adapt, becoming better at avoiding the medicine.

The end result is that an insecticide that previously killed 99 percent of a population may only kill half. Then that 50 percent gets better at avoiding the insecticide’s effects and the insecticide becomes essentially useless.

Particularly persistent pests

You probably can guess two of the pests that are most difficult to get rid of, because they’ve plagued American homes for years: cockroaches and bed bugs. Every time a new insecticide is introduced for roaches, they seem to quickly adapt and become resistant to the spray’s effects. Insecticides are almost completely ineffective against bed bugs, which have been spreading especially in cities.
