Tools for Cockroach Control
Recommend using sticky traps, cockroach bait, and moderate-strength liquid spray treatment.
Specific Treatment Method
Suggest residents clear the kitchen, clean the floor, move utensils and kitchenware from under the countertops, and remove drawers. Disconnect appliances such as the refrigerator, microwave, and dishwasher. Use a liquid insecticide spray, targeting the areas where cockroaches are found and the surrounding crevices, ensuring sufficient coverage from all angles. If using a pre-diluted commercial insecticide, it is advisable to shake it well before use to prevent settling and layering that may impact effectiveness.
Recommended Usage
A specially formulated natural plant aromatic oil cockroach spray (concentrated form) is the latest generation of non-chemical insecticide, primarily composed of natural plant ingredients including essential oils and emulsifiers. It is safe and effective, capable of physically eliminating all stages of cockroaches, including eggs and nymphs. The usage method is the same as regular insecticides, simply dissolve and mix it well before spraying. Note: It is not recommended to use it around stovetops, electrical switches, and outlets.
Post-Treatment Maintenance
After spraying liquid insecticides, it is necessary to strengthen cleaning efforts, seal all water sources, and cut off the cockroaches' food supply, especially food particles on the floor and countertops. In crucial areas where cockroaches have been observed, cockroach bait (powder) and attractant-based sticky traps can be placed to continuously monitor and control potential new generations of cockroaches.
Liquid sprays, bait, and specific placement of sticky traps - refer to the accompanying diagram.
Cockroach Severe Infestation Treatment Plan
On-site Symptoms
During the day, a large number of cockroaches, mainly small ones, are commonly found around the sink, stove, behind the refrigerator, and on the sides of kitchen countertops. There is a significant presence of live cockroaches.
Interpretation of Symptoms
Cockroaches have found suitable habitats in the kitchen with abundant food and water sources. They have begun to reproduce in large numbers, increasing their population and spreading from their initial location to other areas.
Required Tools
It is recommended to use the latest registered strong liquid spray and powdered insecticides. Additionally, it is advised to use bait, gel, and cockroach traps with attractants for subsequent maintenance.
Specific Treatment Method
Residents must clear the kitchen, clean the floor, remove utensils and kitchenware from underneath the countertops, and move drawers. Appliances such as the refrigerator, microwave, and dishwasher should be turned off. Unnecessary items should be thoroughly cleaned.
Use liquid insecticide spray in the areas where cockroaches are found, including the surrounding gaps and other locations such as underneath the sink, around the stove, behind the refrigerator, along the bottom edge and sides of the kitchen countertops. Pay particular attention to the corners, gaps in cabinet partitions, and wooden utensils that have not been used for a long time. Ensure that an adequate amount of insecticide is sprayed, covering every angle.
Cockroaches tend to gather in groups and hide. If a large-scale aggregation is observed, it is recommended to prepare liquid insecticides in advance, increase the pressure in the sprayer, apply the spray around the perimeter, seal possible escape routes, and then target the center of the group to prevent most cockroaches from escaping and spreading.
Precautions
When using liquid insecticides, it is important to control the concentration. Before treating the refrigerator, it should be turned off and allowed to cool. Check the condition of the old door seals and the bottom of the refrigerator for any repairs or replacement needed.
After liquid treatment, allow ventilation and drying for a few hours before applying powdered insecticide to surfaces and gaps. If the liquid has not completely dried, use water-resistant powder as they are highly effective against remaining cockroach eggs and the next generation of cockroaches, with a longer effective period.
In addition to sprays and powders, you can consider using a combination of non-woven fabric and silica powder. Apply non-toxic powder evenly on the non-woven fabric using high-tech electromagnetic charge devices, and then place it in common areas of the kitchen such as the lower part of the countertop and the sticky edges underneath the sink. This method is convenient for killing surrounding cockroaches, easy to operate, and highly effective.
For cabinet partitions, cut them into appropriate sizes and place them in suitable positions to protect adjacent surfaces, maintain aesthetics, and prevent cockroach breeding and settlement.
In the subsequent prevention and maintenance work, apart from spraying various insecticides, it is crucial to strictly strengthen cleaning efforts. Particularly in important areas, especially those near water and heat sources, cockroach gel, powder, and traps with attractants can be placed. This will enable continuous monitoring and treatment of newly hatched cockroaches, preventing the emergence of the next generation.
Please refer to the diagram below for specific placement of bait and traps.

Frequently Asked Questions about Cockroach Extermination
1) Why doesn't sticky paper work effectively in my home?
Typically, the sticky paper available in the market is designed to trap cockroaches as they crawl over it, but it lacks attractants or has attractants with a short duration of effectiveness. Ordinary sticky paper cockroach traps can only be placed flat and have limited positioning, resulting in lower efficiency. Since cockroaches reproduce rapidly, the number caught is usually balanced by the number of newly hatched cockroaches, making ordinary sticky paper traps ineffective in controlling the population.
We recommend using 3D decorative dual-phase attractant cockroach traps with attractants. These traps can be hung in various corners of walls, close to the cockroach activity areas. The highly effective attractant contains food and insect pheromones that work together, slowly releasing over a long lifespan with a large capacity, resulting in higher efficiency.
2) Will children and pets get poisoned if they come into contact with cockroach pesticides?
Generally, the active ingredients used in cockroach pesticides are only present in small concentrations, so they do not have a significant impact on humans and pets. Moreover, even if accidentally ingested, the stomach acid of mammals will break down most of the active ingredients, reducing the risk of poisoning. However, it is important to take precautions and install the pesticides in secure boxes to prevent children and pets from accidental ingestion. Additionally, care should be taken to avoid contaminating food with the pesticides to prevent bacterial infections and food poisoning.
3) Should I spray pesticides everywhere in my home to deal with cockroaches? How can I find their hiding spots?
Cockroaches generally prefer warm and humid crevices, often located not too far from a water source. You can set up cockroach traps near areas such as the sink and behind the refrigerator compressor, as these places are more likely to come into contact with liquid water.
Other possible hiding spots include gaps at the ends of kitchen countertops, the junction between walls and countertops, and the back of cabinet drawers. Additionally, some secondary locations where cockroaches may hide include damaged refrigerator seals, around old-style stove fuse boxes, behind coffee machines, and inside microwave ovens. Bedrooms may only have cockroaches in special cases, such as when children consume food in the bedroom and attract them with food residues. Therefore, it is generally not necessary to spray pesticides everywhere; a few cockroach traps are sufficient for control.
4) Why do I feel that frequently used pesticides are less effective now?
Cockroaches are ancient creatures, older than dinosaurs, and during their coevolution with humans, they have developed genetic simplicity, making them prone to mutations and having strong reproductive capabilities. As a result, they can develop resistance to commonly used insecticides due to repeated exposure.
The commonly used pesticides nowadays are mainly pyrethroids, which have been used for over 50 years. Through prolonged use, the individuals in the cockroach population that are frequently exposed to these pesticides gradually develop resistance, including resistance to gel baits. Due to legal regulations and the interests of large manufacturers, the market is often flooded with products that have developed resistance. Using these products not only wastes resources but also causes environmental pollution. Therefore, we strongly recommend using new products that have not developed resistance.
5) How should I handle it if there are cockroaches hiding in the microwave or stove?
Some customers have found cockroaches in household appliances, especially in display screens, as the slow heating of appliance components attracts cockroaches.
Common methods of dealing with this issue include installing cockroach traps with attractants at the bottom of the appliances and then turning off the power. Typically, after a few days, all the cockroaches will be attracted out.
Another method is to use aerosol insecticides in cans. After turning off the power, the insecticide can be sprayed through openings, and then the appliances can be sealed in plastic bags for several hours, effectively killing most of the cockroaches.
6) How should I choose between powder and liquid pesticides? Why do small cockroaches appear a few days later? How can I prevent this?
Generally, common liquid sprays for cockroaches can quickly knock down and kill adult cockroaches, but they usually have little effect on cockroach eggs due to their protective hard shells. However, after a period of time, newly hatched nymphs are not usually affected by the residual pesticide in ordinary liquid sprays. Therefore, we recommend using a combination of multiple methods, with a particular emphasis on using powder pesticides. Powder pesticides have longer-lasting and more stable effects, especially in killing cockroach eggs. However, the knockdown speed of powder pesticides is slower, so it is advisable to use them in combination with liquid sprays.
Additionally, it is recommended to install cockroach traps with delayed-action attractants to increase capture rates and control the next generation of cockroaches. To prevent cockroaches from reappearing, it is necessary to maintain cleanliness and hygiene indoors, regularly clean up garbage, seal off warm and humid crevices, avoid the accumulation of food residues, regularly clean the kitchen and utensils, and periodically inspect and replace cockroach traps.
