Roach is an insect most people are disgusted by. Sadly, these bugs can survive in almost all kinds of extreme conditions. Regardless of your opinion on roaches, one has to admit that these bugs are really something special.

If their legs are hurt or cut off, they will re-grow! If you leave some biscuit bits on the carpet, they will disappear in a second. If you try to destroy them with bacteria and other pathogens, these bugs will remain healthy thanks to the antibiotics they produce!

They have an almost supernatural sense of smell. And above all, they can eat absolutely everything, and survive in brutal conditions. However, there is a way to get rid of them! Stay with us and learn more on destroying this menace for good.

What is a professional roach killer?

A professional roach killer is a product in a liquid form, or in form of a spray, poison bait or trap that is designed specially to kill the roaches.  These are heavy-duty sprays, gels or liquids used by professional services. Today, these products are also available to anyone else dealing with roaches who want to exterminate them by himself/herself.

The most popular type of professional roach killers today is the gel bait. Why? The unique combination of attractants and poison make these bugs gather, expecting a feast, but they end up consuming the poison. We will talk more about the way in which the roach killers work in the following section.

How do Roach Killer work?

You should know how roach killers work in detail before making your final decision and buying a roach killer product. Different types of products have different work principles. Let’s see how poison gels, sticky glues, killer sprays, acid products, and IGR products work.

Poison gel

Poison gel and poison gel baits work slowly to eliminate all the roaches there are. These products are perfect, as they are very effective – up to 100 %! Their key characteristics are slow elimination process and eliminating the whole population of roaches.

Sticky Glue

The greatest disadvantage of this, somewhat old-fashioned, model is the fact that it works only for the roaches that get trapped. It can kill a limited number of roaches, but those that get trapped do die. We would say that its effectiveness is around 50 %.

Spray

Roach killer sprays are very fast, but they kill only the bugs that are directly affected by the spray. Therefore, we would again mark the effectiveness of this product at 50 %.

Acid

When we say roach killing acid, we imply boric acid. Its key features include a very slow, but steady process of pest elimination. It is based on the fact that boric acid dehydrates the bugs. Another benefit of this kind of roach killers is the fact that boric acid is not toxic. Also, it is affordable. We would mark its effectiveness as 100 %. If you want to learn more about boric acid and safe sellers, take a look at this article.

IGR

These products work on a sophisticated principle of sterilizing the adult bug and stopping the growth of the larva, thus slowly, but definitely, eliminating the whole population. The only disadvantage is the fact that it is a very slow process and that most people want a faster solution. It will take four to six weeks to completely eliminate the population. However, its effectiveness is 100 %.

How to choose the best roach killers in the market?

There are some tips and guidelines that can help you choose the best roach killer in the market. First of all, think of your safety. If you have kids or pets, make sure not to choose poisonous products. These can be lethal for your child, and also for your pets if they come in contact with the product, which is very likely, especially if your child is more than 1 year old.

Next, look for the effectiveness of the product. If you want an urgent solution, i.e. you want your house to be immediately free from roaches, opt for the products that show effect very quickly. You don’t want the IGR products, nor the boric acid. You should probably opt for a spray, or, even better, a combination of spray and gel, or several products to cover the gaps. If you want to kill individual roaches, you should definitely opt for a knockdown roach killer spray.

Also, remember that you must check on the product label whether the product is effective on German or American roaches. Some products are good for both, but some are made for one kind only.

Frequently Asked Questions

“Where should I apply the spray or liquid?”

You should apply the spray directly onto the surfaces where roaches are often seen, especially into the cracks, because these are their favorite places to hide. There are some other strategic places where roaches often hide, such as underneath the kitchen sinks, in the bathrooms and all other dark and humid places. You should spray the product along the pipelines, especially around the cracks where the pipes enter the walls.

Don’t forget other dark places in the kitchen and the bathroom, such as under large appliances, including the stove, dishwasher, and the refrigerator, as well as behind the kitchen cabinets. Similarly, spray the product under the cabinets in your laundry room as these humid zones are the favorite living environments for roaches. Don’t apply the product on baseboards.

“Why the roach doesn’t die immediately if I spray it with the roach killer product?”

If the roach doesn’t die after you sprayed it, there are two possibilities. Either your spray is not suitable for the type of the roach (there is German and American roach, as you already know), or the spray you are using is designed to provide a slow kill.

You should wait for a few minutes, or up to one hour for them to die if your spray has an instant effect, and wait longer if it is a slow-kill product.

“What are the signs that I have roaches in my house?”

If you doubt that you have roaches in your house, but you are not 100 % positive, look for the following signs. There are clearly visible roach droppings around your kitchen, bathroom, and other humid places. You will also notice an unusual odor you hadn’t noticed before. There are also smear marks and shed skin. If you look carefully, you will see the ootheca – roach eggs.

In advanced stages, you will notice even damage caused by these awful bugs. People usually notice chewed packaging. Moreover, you will see the roaches or their dead bodies. You should check your kitchen, bathrooms, laundry rooms, and basements for these bugs.

“How do I prevent roaches?”

You should know what attracts roaches in order to be able to prevent them from coming to your home. First of all, you must know that food and water, as well as places to hide – a secure shelter, is what they are looking for.

You should cut the access to food, especially garbage, liquids (spilled food and stains on the floor), food residues, etc. You must keep the food in clean packaging. Make sure you keep your food in places designed for food storing. Practice eating your food in one place, one room, be it dining room or the kitchen, instead of eating in different rooms.

Also, you should eliminate all kinds of places that resemble cracks and “caves” – good places to hide. This implies piles of newspapers and things you don’t regularly use.

Last but not least, increase the level of hygiene and improve the overall maintenance of the property, apartment, building, house, etc., which will help prevent roaches from entering your place.
