When it comes to German cockroaches, you have to face the fact that it’s hard to kill all of them at once because of their quick rate of reproduction. Moreover, they are good at hiding and protecting themselves. No insecticide can kill German cockroach egg capsules because they can’t penetrate the egg cases.
Thus, you need a solution that can deal with a big group of German roaches. BASF - BCBI10113 - 792075 Insecticide features the SmartCap Technology that produces a shell to protect the active ingredient. If a tiny lethal dose attacks a German cockroach, he won’t die immediately. Instead, it returns its nest and transfers this poison to other roaches.

How To Choose The Best Insecticide For Roaches?
What Is The Exact Insect You Need To Deal With?
Roaches have around 4000 species, and each species will resist different chemicals, so you can’t choose a product at random. For example, what kill German roaches is safe for Brown-hand roaches and vice versa,
Although you can easily buy “an all-in-one insecticide,” killing all types of common household insects on the market, it is just efficient to an extent. Even a wide-spectrum product is more efficient to fight against some and less effective to treat others.
Identifying the exact nature of the pest problem can determine chemicals that can deal with your problem efficiently.
Will You Use Insecticide Indoors Or Outdoors?
Though some products are designed for indoor and outdoor uses, their effect will be decreased under the impact of weather. If your outdoor area is usually affected by rain, wind, or sunlight, you should choose one for indoor use and a stronger product for outdoor use.
Do You Want To Use A More Toxic Or Less Toxic Insecticide?
I am sure that most of you want to use a non-toxic insecticide. Though this choice is safe, it is less efficient. A family with many sensitive things like flowers, bushes, and fruit trees shouldn’t choose more toxic products.
I strongly recommend you correctly apply a high-quality non-toxic product because using it improperly can undermine the effect.
However, if you don’t grow any plants and your family doesn’t have children and pets, you should invest in a higher-toxic insecticide to treat your problem efficiently and quickly.
How Many Insecticides Do You Need?
When mixing a large bottle of insecticide with water, you might have hundreds of gallons of roach poison.
Do You Need That Much?
I don’t know, but it’s not essential to purchase more than what you need. However, make sure that you don’t need to buy extra insecticide while fighting against roaches.
Is An Insecticide With Odor Or Odorless Product Better?
Don’t use a product with a chemical odor inside because it causes some health problems. It’s not a thing that you should smell.
Using a product with an odor outside isn’t a big problem because it’s airy. In the event of a slight odor, you can't even smell anything in your yard.
Are Oily Stains Your Problem?
Some insecticides will leave oily residue stains on the surface, so consider where you will apply your insecticide. If your surface is soft soil outdoors, you don’t have to care about this problem. If you want to use it indoors or on a permanent solid surface outdoors, you shouldn’t buy a product that will produce oily stains.
Do You Need Any Tools To Set Up The Insecticide?
To answer this question, you need to determine where and how you will apply the product. Some require essential tools, while other places don’t need anything. If you need tools, you can invest in a set of insecticide and other items.
Which Brands Make The Best Insecticide For Roaches?
Do you know why I listed 2 products of the Syngenta brand in this article? Everything happens for a reason.
This brand is a group of 4 business units including Syngenta Group China, ADAMA, Syngenta Seeds, and Syngenta Crop Protection. They always applies the most local agricultural technology in the world to their products, so you can believe in their quality product.
Is one roach a sign of infestation?
This depends on the type of roach that you discovered. Smoky brown Cockroach, Oriental Cockroach, and American Cockroach shouldn’t make you worried because they usually live a solitary life. They like to live outdoors. But, these roaches might enter your home if they see available food and water by accident.
In this case, you simply sweep them out of your house or kill them.
However, one German cockroach is a sign of infestation because they live with dozens to hundreds of other roaches. Even this type of roach can quickly reproduce and multiply.
If you see a German cockroach in the middle of the day, the condition is severe. This type of cockroach usually hides in their nest to rest during the day and work at night. Going out during the day means their nest is so large that one or some of them must look for another place to rest.
How do I get rid of roaches permanently?
Removing what attracts roaches in your home can get rid of them permanently. Although it’s hard to remove their good growing condition: warm and humid climate, you can wash your dirty dishes, pick up crumbs and pet food on the floors, and remove leftover food in empty cans, throw garbage away, eliminate grease from the stovetop, and seal food in your containers.
In sum, roaches are not interested in a clean house, so you just need to clean your home thoroughly.
You can also use a store-bought trap and bait to attract roaches. This way might take up to 14 days, so you need to periodically check the trap.
You can disguise chemical baits as a food source and put them near your garbage cans or other areas where roaches usually visit, like underneath the sink, cabinet, and your bathroom. When roaches consume the insecticide, they will die after returning to their nests. Other roaches will eat the dead roaches and spread the poison to the whole nest.
It’s okay to spray a diluted liquid concentrate to areas where roaches hide, such as cracks and crevices. You can use this solution to mop your floor or wipe your counter.
Does having roaches mean your house is dirty?
No. Roaches enter your house because they can find food and water inside, not because of your dirty home.
How do you find a roach nest?
Usually, roaches will build their nests behind refrigerators, in crawl spaces, kitchen cabinets, corners, and compact areas.
You can find roach nests through the following signs: cast skin mounds, egg cases, dark spots or smears, and cockroaches (live and dead). Don’t forget to check under your furniture, in drawers, or under your cupboards.
How long does it take to get rid of a roach infestation?
One week or more
The best insecticide for roaches must be efficient enough to help you remove roaches in your home and safe enough not to badly affect people and pets, and your plants’ health.
