What Methods and Chemicals Do Exterminators Use for Roaches?

Finding a cockroach infestation on your property can come as a terrifying shock. Thanks to their nasty habit of hanging out in drains and sewers, these universally-despised creatures are well-known carriers of diseases. In addition to carrying bacteria all over your home, cockroaches can also cause big problems for allergy sufferers. The feces and shed skin of cockroaches can trigger asthma attacks in those individuals that share their homes with the bugs.

To top off all of that, roaches simply stink. They secrete an oily substance that has a disgusting, musty odor. While this odor can be unnoticeable at first, it can quickly become overpowering as the number of roaches increases. Over time, this odor can even start to affect the taste of food!

Unfortunately, roaches thrive in the company of humans. That is why they can be found invading homes and businesses all over the world. These prolific breeders also multiply at a frightening rate. Just one or two cockroaches can become tens of thousands over the course of a single year. This means that before you know it, you can find yourself dealing with a heavy infestation.

If you find roaches in your house, taking immediate action is crucial. It is relatively easy to deal with a small number of cockroaches. An infestation, on the other hand, will require professional intervention.

If you find a nest of cockroaches on your property, the best thing to do is to call an exterminator – quickly! An exterminator will be able to tackle the problem effectively, getting rid of your roach problem in no time at all. But what methods and chemicals do exterminators use to get rid of roaches? Read on for the techniques that are most commonly used to eliminate everyone’s least-favorite insect!

Gel Bait

Gel baits can be an effective way of eliminating cockroaches. This is why they are often used by pest control experts. These gels use various insecticides and come packaged in a handy syringe. This syringe can apply small amounts of the gel anywhere that roaches lurk around your home, such as in cracks and crevices. The roaches will eat the gel bait and die shortly afterward.

The best thing about gel bait is that, when used with certain insecticides, it can kill several generations of cockroaches. Roaches feed on one another’s bodies, allowing the dead insects to transmit the poison to the living. The droppings of the roaches also pass on the insecticide, thus ensuring widespread death.

Tent Fumigation

The use of tent fumigation for cockroaches is not widely recommended. Cockroaches can wedge themselves into tiny spaces, hiding in the cracks and crevices around your home. This means they can avoid the fumes that settle only on exposed surfaces (such as the floor and furniture). Even if only a few roaches survive, their high reproduction rate means that they can multiply in no time at all. Before you know it, you will find yourself back at square one!

What’s more, the pesticides in these sprays can linger in your home long after the fumigation has ended. This can present a fire hazard and exacerbate asthma symptoms in sufferers.

Insecticides and Chemicals for Cockroach Control 

Boric Acid

Boric acid is one of the most common roach control chemicals. It is often applied as a dust, which is scattered over surfaces around the home. Roaches then crawl over these surfaces and become coated in the powder. They will ingest it when preening their legs and antennae. Since boric acid remains effective almost indefinitely as long as it stays dry, this is a great solution for long-term roach control.

Indoxacarb

Indoxacarb is an insecticide that is highly effective at cockroach eradication. Gel bait often uses it as a component and your pest control expert may also employ indoxacarb to exterminate your roaches. As with boric acid, when live roaches come in contact with the feces and dead bodies of poisoned insects, they become poisoned by indoxacarb as well. This insecticide is, therefore, highly effective and can kill up to three generations of cockroaches.

Hydramethylnon

Roach bait often uses hydramethylnon since it only takes effect once ingested. Once eaten by the cockroach, it causes death by disrupting the metabolic processes and energy production of the pest. This insecticide is highly effective against German roaches.

Conclusion

Cockroach infestations can be a nightmare to deal with. The lightning-fast reproductive rate of these loathsome creatures means that their population can explode in a matter of weeks. This, when added to their ability to squeeze into every tiny crack and crevice, makes them a highly persistent pest. It can be almost impossible to eradicate them without expert assistance.

Calling in a pest control professional is often the best course of action if your roach situation is out of control. They will typically use a gel bait containing various insecticides to effectively kill your cockroaches. Exterminators will sometimes dust chemicals like boric acid over exposed surfaces as an additional weapon in their battle.

Whatever method your exterminator chooses to use, make sure that you also employ preventative measures to keep them from coming back and rid your home of roaches for good!

Is it possible that our landlord/maintenance guy painted the German roaches in the walls and they are eating their way out. We are heavily invested. They didn’t start till the paint started cracking

    Not sure about them having been painted in there, however, roaches do sometimes live in the walls. They have a talent for finding different types of cracks and crevices to crawl through. If you have hollow walls, those can sometimes hold rather severe infestations. To answer your question though, no, I don’ t think they were painted in, I believe it to be more likely that the paint cracking simply gave them a better opportunity to get out.

Help I just moved into an apartment that I think has a roach problem.

    Well, first, you should determine whether or not you are indeed dealing with roaches. If your assumption is correct, you should read our article about getting rid of cockroaches to figure out what your options are.

    Please HELP! My husband and I just signed a new lease on an apartment and as we were cleaning before moving out things in we found roaches. We have sprayed and fogged and we are still seeing them whenever we go in there and the landlord will not help us with the problem. We are expecting another child next month we cannot move into roaches.

    If you feel like trying to deal with the situation yourselves, read this article to see what your options are. Other than that, you can hire an exterminator. Good luck!

German cockroaches particularly large infestations are next to impossible for the homewowner to get rid of. I’ve wasted countless dollars on WP demon, advion gel Fc magnum force gel boric acid diamataceous earth and to be honest they love all that stuff. I could have hired 3 exterminators for the money I’ve wasted. Whatever they use is either a higher potency or an entirely different chemical we can’t buy

I live in a mobile home and I’m infested with black and brown cockroaches I’ve used every kind of spray or liquid or gel that you can buy at Walmart and a couple from do-it-yourself and because I have drug addicts in the mobile park where I live there filthy habits from cascading into my house what is the best method for me eliminating large amounts of roaches at a time? As it stands now I use diatomaceous earth and glue pads

    You can start by reading this article. You might be able to find something well-suited for you. Other than that, is there any chance you might be able to figure out where their entry points are, to seal them off, if possible?
