Cockroaches are creepy and carry pathogens like salmonella. But by the time you begin to see roaches in the home, the infestation has been fully established. Killing cockroaches needs a two-pronged attack to kill existing roaches and making sure they don’t come back. Keep food in sealed containers and regularly clean up any messes that could feed roaches. Clean up any puddles on the floor to deprive roaches of an easy access water supply
For severe infestations, contact a professional pest control management company. They are able to get access to pesticides that are not available over the counter. These insecticides also include insect growth regulators (IGRs) that helps prevent juvenile roaches from maturing into adults. If they can’t mature, they can’t breed.
Using Bait Stations
Over the counter roach baits and traps work very well in reducing cockroach populations. Place bait stations in dark hidden corners of counters, under sinks and behind large appliances like refrigerators. Also place them anywhere cockroaches have been seen. This will be the best chance of making sure cockroaches come into contact with the baited food inside of the traps.
Roaches live in colonies. They share food among themselves. If a roach brings back food laced with insecticide, then this food is shared with other colony members. This kills roaches more quickly than with conventional sprays. Bait stations can be used in combination with over the counter sticky traps. Replace traps and bait stations according to the manufacturer’s instructions.
What About Roach Sprays?
Roach sprays work by coming into direct contact with a roach’s body. The problem with sprays that is that they are a very slow way to kill roaches one at a time. Fumes from roach sprays may also sicken children and pets. At best, sprays only work for a short period of time because the surviving roaches quickly breed replacements for the dead roaches.

If you are sick and tired with the cockroach infestation, you need to figure out the right way to deal with it. Sometimes roaches like to come to clean places, so no matter how often you clean your house or whether you are able to keep your house clean, the possibility of having such roaches infestation is still wide open. So, if you want to get rid of the cockroach, there are simple and natural ways to do so.

Here are the steps to do so:

• When you find a cockroach, try to trace back where it comes from. Roaches usually have their own lairs, so being patient can help finding out the culprit of your issues. When you have found out the source of the issue, you can deal with it. Most lairs usually come in the form of wall cracks, the leaked pipe or drainage, or such thing alike. You can seal it off and make sure that the cracks are fully covered.
• Cut them off from any food source. Be sure that you have kept your foods or drinks in cupboard or containers that are sealed off perfectly.
• Cockroach doesn’t only live inside a house but outside as well. It would be better if you can block off the access from the outer world so they can’t come into your house easily. For instance, you can install screen door to block the access. You can also use a home remedy solution to kill the roaches. Mix the flour, borax powder, and also cocoa powder before you can spread the mixture on places where the cockroach often comes.
• Use certain pesticides to kill the roaches when you spot them. But be sure that the pesticides don’t come in contact with any food or liquid nearby.

And if all the methods above don’t really work, you can hire professional pest control experts that can help dealing with the cockroach infestation. They should be able to provide solution and also preventive ways to deal with the issue with affordable price range.

At the moment that you notice the appearance of a cockroach, it implies your house is outnumbered with them according to iceberg phenomenon.

Spraying, glue trap,bait in a bottle, painting oil on a wall, syrup mixed with a cement can probably contain their population temporarily. But, soon new born cockroaches will appear again since there are  eggs underground waiting to hatch out. Therefore, you have to solve the cause of the problem.

Basic ways to get rid of cockroaches yourself

you can use bait to trap a cockroach. First of all, you have to detect its nest. Then, you use a roach bait made from boric acid (do not use a powder one) (Art Ball Knock Plus brand is generally sold). While eating the bait, a cockroach will be touched with boric acid on its legs and then will clean itself by licking them making the acid swallowed into its body. Moreover, the acid is able to penetrate straight into the body through its rough skin. After four days of eating the bait, its foregut will be burst apart and a cockroach will die. Its fellow cockroaches then will come and eat a dead one. Soon cannibal cockroaches will be killed as well. As a result, in this way, all the cockroaches in the nest could probably be killed. Besides, the acid also has an effect on a female pregnant cockroach by reducing its Oocytes. The boric acid is very cheap (29 baht for 4 pieces)

There is the disadvantage of getting rid of cockroaches using the boric acid. It takes quite a while to become effective and you have to be patient setting a trap consistently to kill them in every generation.(Cockroach’s egg takes 2 weeks in order to hatch.)

You have to solve the cause of the problem

• Clean you house
• Eat at a proper place
• collect garbages to outside daily
