If making your home less inviting was not enough to curb the problem, you may want to consider using pesticides. The problem is that roaches are immune to many pesticides or can become immune to the ones you use. Start with one method and do the trapping exercise to see if you are having any success.
Diatomaceous Earth and Boric Acid are the two most common dusts. Diatomaceous Earth damages the exoskeletons of insects which dehydrates them while Boric Acid poisons them. Diatomaceous Earth works faster, almost immediately compared to Boric Acid which can take in excess of a week. However, roaches are less likely to be immune to Boric Acid and are not repelled by it. When you use dusts, take care not to breathe them in.
Hydramethylnon Bait Stations
Some roach bait stations have varieties and use Hydramethylnon poison which kills the roaches in 3 days after the consumption. These bait stations allow you to use poison without covering your house, but should still be kept out of the reach of pets and children. The bait stations work well, but can be used up quickly in highly infested areas. Check the bait stations and change them frequently.
Insect growth regulators work breaking up the natural breeding cycle of insects. In roaches, they cause adult sterility in exposed eggs and juveniles. This means that eventually your population of roaches should go extinct. However, if there are unaffected roaches nearby, you could just be re-infested again.
Carbon Dioxide Fumigation
Carbon Dioxide is used by filling large plastic bags with roach infested items and replacing the air with Carbon Dioxide and roaches cannot breathe and die.
Steaming holes cracks and underneath appliances can kill roaches without the use of pesticides.
Foggers are pretty pointless. The roaches will retreat, hiding safely from the poison and come back out when the coast is clear. All you will have managed to do is poison your own environment. The residue will not affect the roaches at all. It is best not to bother with foggers.
Well, prevention is the best medicine. The roaches come to your home to eat, so you just don’t give them reasons to visit your house. Do not leave food exposed, unwashed dishes in the sink, open cereal boxes, etc. Beyond these things, roaches even feed on organic debris and anything that has fallen on to the floor like dry skin. In short, maintaining hygiene and cleanliness in your home will cause them to look for other places to eat.
The same rules apply to those roaches living outside around your home. Clean away dead leaves close to the house and clean any places that might be damp and shaded.
You can create a humane trap; take a jar, place a piece of bread inside and smear Vaseline all around the edge of the jar. The roaches will be enthusiastic to visit the jar but will not be able to get out past the vaseline.
You can also sue bay leaves which are easily available in supermarket. Roaches absolutely hate bay leaves. They can be put in strategic places. I recommend you to visit TheReviewGurus for more ideas in this regard.
Cockroaches are filthy creatures that just don’t belong in our homes. One sight of these disgusting pests is enough to make our skin crawl and send into a search for a good cockroach killer that will exterminate them completely. Cockroach bait is an effective way of doing just that. It is a food source added with insecticide that lures cockroaches in. The poison level is intentionally low so as not to kill the insects immediately after ingesting it. Instead, they live long enough to crawl back to their dwelling place and communicate to the other cockroaches that a new food source has been found. This way, all of them will eventually consume the bait.
Indoor Cockroach Bait
Indoor cockroach baits usually come in form of gel. This bait can be directly applied on countertops, floors, walls or any surface in the house where cockroaches are often seen crawling. Indoor cockroach baits can also be used in bait stations. Which method to be used will depend on the degree of cockroach infestation you have. Remember to always practice safety precautions in using either two methods.
Severe infestations may require the use of a gel bait, especially if other treatments employed have been proven to be ineffective. It is more effective in such a way that exposed cockroaches will be covered with poisonous gel and the others that come in contact with it will also be poisoned. Gel baits can be applied along countertops, cabinets and furniture edges. Apply gel baits with extra caution as they pose a high risk to children and pets inside your home. It is always a wise idea to consult a professional exterminator to get advice on how to use this type of cockroach killer safely as well as effectively.
Cockroach Bait Stations
This cockroach killer is considered to be a much safer alternative in eliminating these pesky insects, especially when there are kids and pets inside the house. Bait stations are built like little structures that have a small entrance where cockroaches can pass through. Strategically place the stations behind appliances such as under the kitchen sink, inside closets or cabinets, and basically any place where cockroaches are usually seen as they search for food sources. Depending on infestation’s severity, cockroach killer stations may last for one week to a month. You may have to continue supplying the stations with food baits until you are completely sure that the infestation is over.
Outdoor Cockroach Bait
Outdoor baits are commonly used in areas where climate is very hot. Although cockroaches are normally seen inside homes, they are also known to forage for food around house’s exterior. Outdoor baits usually come in granules that are supposed to be scattered around home. They are formulated to be weather-resistant, so that they retain their affectivity even after constant exposure to heat or heavy rainfall.
