Final answer:
The insects found in the kitchen are likely not ticks and are more likely to be small insects such as mites or fleas. To get rid of them, it is important to remove the pigeons and their nests in the space between the roof and the ceiling. Professional pest control services can help with this.
Step-by-step explanation:
The insects that you found in your kitchen are most likely not ticks. Ticks are arachnids and are typically larger, around 5mm. The insects you described, being between 0.5 and 1mm, are more likely to be other types of small insects, such as mites or fleas. However, without clear pictures, it's difficult to accurately identify the insects.
To get rid of these insects, you should focus on eliminating their source, which is the pigeons and their nests in the space between the roof and the ceiling. You can hire professional pest control services to remove the pigeons and clean the area thoroughly to prevent further infestation.
You do not necessarily need to leave the house during this process, but it is advisable to keep your kitchen and living spaces well-ventilated to minimize any potential health risks associated with the presence of pests.
