How to Get Rid of German Roaches

German cockroaches are a common pest in most homes across America. They are quick to multiply and can have huge clans in days. The sight of gross cockroaches can make people go through the roof. They are resistant to pesticides due to their high level of evolution and can be very hard to get rid of due to the high roach lifespan.

The discovery of German cockroaches (Blattella germanica) in your home can be distressing. These prolific pests reproduce rapidly and possess remarkable resilience, making infestations challenging to eradicate. However, swift and decisive action is vital for effective control and to restore peace in your living space.

CDC research has said that roaches do not bite, but they can probably scratch humans with their tiny legs. As roaches travel in the dirtiest and dingy places, they tend to carry many diseases with them. So, how do you get rid of German roaches resistant to most pesticides?

This guide will explore the most efficient strategies for eliminating German roaches quickly. We’ll cover a range of techniques including potent baits, targeted insecticides, natural remedies, and expert prevention measures. By following these approaches, you can achieve a pest-free environment and regain control of your home.

Key takeaways

  • German cockroaches are common household pests that multiply quickly and carry diseases.
  • Methods to get rid of them include bait, pesticides, and natural remedies like vinegar, baking soda, and catnip.
  • Keep your house clean and seal off openings to prevent infestations. Call exterminators for severe cases.

How to kill German roaches

There are still many ways to get them out of the house. Here we have listed out the best way to get rid of these unwanted pests, and we hope they help you beat these filthy pests.

1. Use bait

One of the best ways is to set baits for them. German roaches enter your homes in search of food. So, you can leave out pieces of food coated in insecticide on your kitchen floor or kitchen counter. Roaches come out at night, and they will definitely take the bait, eat these food baits, and even take some back to their colony and kill the whole clan.

How it works: Roach baits contain slow-acting insecticides mixed with food attractants. Roaches consume the bait and take it back to their nests, where the poison spreads through the rest of the colony.

Best types: Look for gel baits containing active ingredients like fipronil, hydramethylnon, or indoxacarb. They are typically applied in small dots in areas where roaches are seen. Consider bait stations for longer-lasting control and keeping the bait off open surfaces.

Pros: Highly effective, can eliminate entire colonies, easy to use.

Cons: Can take a few days or weeks for substantial results.

2. Spraying pesticides

How to kill German cockroaches with pesticides? Not every pesticide works well on roaches. You can research the market and find one that kills them. But be careful with pesticides. Try not to spray them on kitchen counters, food objects, or porous material. It is best to spray them in pipes, cracks, sewer lines, and behind cabinets to directly kill the colony of the roaches.

How it works: Insecticides can provide quick knockdown of visible roaches and residual effects to prevent others from entering treated areas.

Best types: Select products labeled specifically for cockroach control. Look for ingredients like cyfluthrin, deltamethrin, or bifenthrin. Use both a liquid spray for targeting cracks and crevices, and an aerosol spray for flushing roaches out of hiding.

Pros: Provides fast results, useful for spot treatments

Cons: May not penetrate nests or kill eggs, less effective on insecticide-resistant populations.

3. Natural methods

While generally less potent than commercial pesticides, here are some natural options:

  • Vinegar: You can make a solution of 50-50 vinegar and water to wipe the floor and surfaces where you spotted the roaches crawling by. Exposure to vinegar and its citric acid can instantly suffocate German roaches and kill them.
  • Baking soda: The baking soda you use for cooking can be pretty dangerous for German roaches. It combines equal parts of granulated sugar with baking soda and places them in strategic areas where the roaches reside. Within a few days, the number of roaches will decline, and they will completely perish in a week or two.
  • Borax: Borax used as a laundry cleaner is quite lethal for German cockroach nymphs and the parent roaches. You can sprinkle some borax in infested areas, and eating this will disrupt the digestive system of the roaches and kill them.
  • Diatomaceous earth (DE): DE consists of diatoms (unicellular aquatic plants) which can be a major killer for German cockroaches. The dust of the DE soaks through the exoskeleton or the hard skin of the roaches soaks up all the moisture from their body and kills them. But you need to camouflage the DE, mix it with equal parts of cocoa powder, and sprinkle it on affected areas.
  • Catnip: Catnip does not necessarily kill German roaches, but it repels them from entering your house. Nepetalactone, the chemical in catnip, acts as a natural repellent. You can make small packs of catnip and place them at strategic points to stop German roaches from entering your homes.
  • Rubbing alcohol: You can combine rubbing alcohol with water and spray it on roaches to kill them. The high intensity of the alcohol will kill them instantly.

4. Consider Professional Help

There are times when DIY methods simply aren’t enough. Stubborn infestations that keep returning or initial outbreaks that seem overwhelming might signal it’s time to enlist professional help. Pest control experts have years of experience dealing with German roaches specifically. They understand the insects’ behaviors and hiding preferences, allowing them to locate and treat problem areas you might easily miss.

Furthermore, exterminators have access to a wider range of potent insecticides, often including those that aren’t available to the average homeowner. This means faster, more thorough results. A reputable exterminator will also devise a customized pest control plan that includes not only initial treatment but potentially follow-up visits and preventative measures to give you the best chance of keeping your home roach-free for the long term.

Understanding German Cockroach

Before diving into elimination strategies, it’s essential to understand the enemy. German roaches are one of the most common household pests worldwide. Here’s a quick breakdown of their key characteristics:

  • Appearance: Small and light brown with two dark stripes running lengthwise behind their heads. Nymphs (young roaches) are smaller and darker.
  • Size: Adults measure around 1/2 to 5/8 of an inch in length.
  • Reproduction: German roaches are prolific breeders. Females can produce multiple egg capsules in their lifetime, each containing dozens of eggs.
  • Diet: These pests are omnivores, scavenging on a wide range of food scraps, crumbs, and even non-food items like soap and glue.
  • Habitats: They thrive in warm, humid areas with access to food and water. Kitchens, bathrooms, and near garbage cans are prime nesting spots.

Why are they so hard to get rid of?

German cockroaches have evolved a set of characteristics that make them exceptionally difficult to eradicate:

Rapid reproduction

A single female German cockroach and her offspring can produce hundreds of thousands of roaches within a year. This means that even a small initial infestation can quickly escalate into a major problem.


German roaches are remarkably adaptable. They can survive in a wide range of temperatures and conditions, and some populations have developed resistance to common insecticides. This resilience makes it necessary to use a variety of control methods and potentially rotate through different products.

Hiding experts

Their flat bodies allow them to squeeze into incredibly tight spaces, making them difficult to locate and treat directly. They also tend to be most active at night, further reducing their visibility.

Opportunistic feeders

German roaches aren’t picky eaters. They’ll consume almost anything, from crumbs and grease to soap, glue, and even book bindings. This makes it hard to eliminate their food sources completely.

These traits highlight why a multifaceted approach is crucial for successfully battling a German roach infestation.

Why and how do German cockroaches enter your home?

Do not let these tiny scary pests roaming around your home question your house choice and lifestyle. Cockroach infestations are much more common than you would think. They enter homes searching for food and a warm and moist space to grow their clan.

So, where do these come from? Unfortunately, German roaches can enter your home from any sort of opening through pipes, doors, windows, and sewers; the possibilities are endless.

  • Coming in with groceries, boxes, or other items: German roaches or their egg cases can hitch a ride on secondhand furniture, cardboard boxes, grocery bags, and other objects unknowingly brought into your home.
  • Traveling through cracks or gaps: German roaches can squeeze through small openings in walls, around pipes, or underneath doors.
  • Hitchhiking from neighbors: In apartments or multi-unit buildings, infestations can spread from one unit to another through shared walls or ventilation systems.

Once they enter your homes, they make homes in the smallest of cracks in your house, and you can hardly notice them before a tiny one goes flying across your bedroom.

Prevent German roaches from coming into your home

Prevention is always the best cure when dealing with pests. If you do not want to have a huge roach infestation inside your house, you can take these measures to prevent them.

1. Seal Entry Points

Check for and seal any cracks, gaps, or holes in your home’s foundation, walls, and around doors and windows. Use caulk, expanding foam, or weatherstripping to block potential entryways.

2. Keep it Clean

Meticulous cleaning is essential! Wipe up spills immediately, wash dishes promptly, and don’t leave dirty dishes overnight. Ensure there is no litter inside your house or particles of food lying around. Clean it up to stop attracting those dirty pests. Vacuum regularly to remove crumbs and food debris.

3. Eliminate Moisture

Fix leaky faucets and pipes. Run a dehumidifier in damp areas like basements or bathrooms. Use a dehumidifier inside your home to make your house less damp to repel roaches.

4. Empty pet food containers

If you are careless and keep your pet food lying around in bowls hoping your pets will eat them. Well, that can even get German roaches to feed on them and grow their colony on all the free pet food.

5. Keep food away/sealed

Use airtight containers for dry goods, and refrigerate perishable foods. Avoid leaving pet food out overnight. Do not keep food open or unattended. You must always seal them in tight containers and keep them in closed cupboards or inside the fridge.

6. Keep trash out

Take out your trash regularly. If you are letting trash lie around for days, they can be real cozy breeding grounds for the roaches.

7. Check Incoming Items

Inspect used furniture, boxes, and grocery bags for signs of roaches or their egg cases before bringing them into your home.

How to Prevent Further German Roach Infestation

Even after success in eliminating a German roach infestation, it’s vital to stay proactive to prevent them from returning. Sticky traps, strategically placed in high-risk areas like under the kitchen sink, behind appliances, or in bathroom cabinets, act as an early warning system. These traps will alert you to even small numbers of roaches, allowing you to take quick countermeasures before the problem spirals out of control.

Maintaining your cleaning routine is non-negotiable. Pay particular attention to hotspots, like the areas around your stove, underneath your refrigerator, and inside pantry cupboards, where crumbs and food debris may accumulate. Additionally, routinely inspect your home for any new cracks or gaps that might develop. Roaches are experts at squeezing through surprisingly small spaces, so recaulking around windows or addressing any damage to your foundation is vital for continued roach prevention.

Eradicate Your Roach Problem: Sustain Your Pest-Free Home

German roach infestations can easily return, so it’s crucial to stay proactive to keep your home free of these pests.

Make sure to seal all potential entry points, including even the smallest cracks or gaps. Fix leaky plumbing and keep moisture levels low to create an environment that roaches dislike. Additionally, a strong focus on cleanliness is key. Keep food in airtight containers, clean up any spills or crumbs immediately, and clean your kitchen and food areas often. These actions will deter those roaches and help ensure your home stays pest-free.
