The answer to 'why do I have cricket' is that crickets are common household pests that can infest homes, especially during the warmer months. Crickets are attracted to warmth, moisture, and food sources found in homes, and they can enter through cracks and crevices around windows, doors, and pipes.
Common signs of a cricket infestation include hearing their chirping noises, seeing them jumping around, and finding their droppings or shed exoskeletons. While crickets are generally harmless, they can be a nuisance and may chew on fabrics, paper, and other materials in your home.
