Cockroach Q&A

Cockroach, Questions and Answers


Here are some common questions a business owner or a homeowner might have regarding cockroaches:


How do I know a cockroach is a cockroach?
It may sound like a silly question, but it is definitely a common one. You can decipher whether an insect is a cockroach by examining their physical body. The German cockroach is the most common in the United States. It has a compressed oval- shaped body with prickly legs, and they are usually 15mm in length (when fully grown). Both male and female cockroaches have wings and their color is of a light-brown tint with two dark stripes running down the thorax.

Are cockroaches dangerous?
The answer is YES. Second to house flies, cockroaches are dangerous because they spread disease. Because cockroaches are exposed and travel through many different habitats, they are susceptible to disease which may ultimately be transmitted to humans. Diseases like salmonella, typhoid, tuberculosis, cholera, and leprosy are a few that can be caused because of cockroach infestations.


What are cockroaches attracted to?
Three simple things attract cockroaches: food, water, and shelter. Foods with starch are preferred, but they will eat generally anything, even concrete

When is the best time to catch or see a cockroach?
Nighttime. Cockroaches are nocturnal – meaning they will come out at night. When trying to catch them, you should be careful. A small lick of light will send them into a scurry.

A friend of mine says cockroaches are common in unclean areas. Is this true?
No, it is not true. As long as food and warmth are present, the cleanest areas are still susceptible to cockroach infestation. That is why a person will often find cockroaches lingering in hotels, restaurants, bakeries, and hospitals. They usually stay in areas around sinks and in drains and cracks.

How do I stop cockroach infestation?
You can’t necessarily stop or prevent an infestation. However, there are many preventative measures you can take in order to minimize the chances of infestation. Good sanitation is not necessary, but it will help with future infestations. Be very cautious of packages that you are brining into your home. Also, eliminate opportunities of infestation by clearing accessible, open food.


Up to how many eggs can cockroaches lay?

The German female cockroach can lay up to 40 eggs. In a lifetime, the female cockroach can produce up to 8 egg cases. It takes roughly three to four months for an egg to develop into an adult cockroach, but a cockroach lives up to only a year.

    how can I get rid of cockroaches permanentaly in my apartment building? Can you recommend some, strong, effective and safe solution?.. I prefer to spray..


  2. 2

    Can I get ride of the roches with the sprays they sell at any store????

  3. 3

    You can most likely kill a roach on contact with the sprays that you can find in your local hardware store. However, for long term treatment, it will not be efficient enough. For full control of roaches, you need baits and residual sprays and although you may be able to find them at local stores, those will not have the same amount of the active ingredient as professional pest control products do. You will only be able to find professional pest control products online or from professional pest control management companies. I hope that helped you!

    Hi Stephanie,
    I’ve never heard of cockroaches travelling around on people or animals, but I really hope they don’t! I know your house is clean, but is it perhaps a bit cluttered or disorganized? Even small cracks between boxes can provide temporary shelters for cockroaches. Thankfully, it seems like yours haven’t reproduced too much yet and that your problem is relatively mild. I would recommend putting the bait traps in the different spots in your apartment (1 trap per spot should do the trick). Let me know if the problem persists or gets worse! Although, just for future reference, if it does get worse, the first thing you want to buy is an IGR.

    Is there a foam I could shoot in my kitchen sink where they are always coming from?

  7. 7

    The best thing for cockroaches is to use a bait type of treatment method. Any kind of foam or contact kill insecticide will just flush them out as an initial method of treatment, however, it will not eradicate the infestation. If you add a bait under the kitchen sink like our bait gels or bait stations, that will target the colony as well as the existing the infestation.

    A family member brought roaches into our house several years ago. We have tried everything from bombing, sprays, dusting, the gel stuff so they can come back & eat it just stayed put & didn’t seem to attract them, having a professional come in(he was a joke because he didn’t believe me about where they were just because he didn’t see them), we have even tried cheap wine in a small bowl hoping to attract them to it. All with minimal success. The family member’s room is a mess & they are no longer actively living here but we can’t just get rid of their stuff as they are in a nursing home due to cancer treatments. We don’t want to take her stuff to her storage area & possibly spread these roaches to unsuspecting people who also have storage containers around her’s. We have 1 3yr old who likes to put things in her mouth, an 8yr old & a 14yr old as well as 3 indoor/outdoor dogs & 4 indoor only cats. The house is a 2 story 130+ yr old house with full basement ( yes I have seen them down there also) & plaster walls. They seem to come out the absolute most when we are cooking something like soup or the like so there is like hot moist air. They had been pretty much contained to the 1st floor but the last few months have started migrating to upstairs as well. What can we do to get rid of these things as cheaply as possible but also health friendly for the kids & pets?

    Hello Paul,
    Roach control will really depend on the species. It sounds like it is a German Roach problem that you have. Take a look at the following link to see WHERE you need to apply the baits and the insecticide. We recommend using both the concentrate liquid contact killer as well as baits like gel baits and bait stations. Here is the link:
    The following link is from Backed By Bayer’s Maxforce roach control site. Suspend SC as well as the Maxforce line of roach baits are very effective for control. All product labels must be read before application. For the concentrate like Suspend, it is best that you apply it and let it completely dry before reentry and gel baits should be applied in areas that you children cannot access. If you have some areas you would like to apply the baits but they are in areas that the children can easily access, we recommend the stations. Keep in mind though that the bait stations for roaches will only fit the smaller species of roaches like the German roaches and the brown-banded roaches. If you have any further questions or comments, please feel free to contact us again.

    Hi Ashley,
    I don’t think it is a huge problem to be worried about but we do recommend regular maintenance and thorough cleaning. If you are seeing roaches regularly, you may have to consider pest control with insecticide. Regularly would be at least 2-3 a week. If you can identify the roaches, that would also be something to consider. If they are large, outdoor roaches, I do not believe that you will have a problem because large, outdoor roaches that are found inside are considered occasional invaders. If they are the smaller, German roaches, then you may have a problem in the future. If you have any questions or comments, please feel free to contact us again.

    Hi Jasmine,
    They may be occasional intruders from the outside or your if you transferred boxes or materials from your parents’ home, they may be from there…Unfortunately, there is no real way to know. You can continue to monitor for roaches with Victor Roach Pheromone Glue Traps which are like regular glue boards, however, they have been coated with a pheromone attractant. These can be placed in corners on top of counters, behind the microwave, behind the fridge, under the sinks, and etc. This will help you monitor and check to see if you have an infestation or any stragglers. If you can identify that you have an infestation, then you can begin treatment with insecticide as well as use non-chemical methods as an integrated approach to treat roaches. If you have any further questions or comments, please feel free to contact us again.
