Mites are extremely tiny round black bugs with no wings and eight legs. While they are rarely harmful to humans other than mild irritation to the skin or allergies, black mites in the house could signal elevated moisture levels or a more significant water issue. One of the most common types of mites is the Clover Mite.
Shape and Size: Bed bugs are flat, oval, and about 5-7mm long. Colour: Typically rusty red or brown, but never truly black.
Bed bugs are primarily attracted to warmth and the carbon dioxide (CO₂) that humans exhale. This is why they tend to gravitate toward areas where people sleep, like beds and couches. They are also drawn to areas with dark crevices and clutter, where they can hide.
Ticks are tiny black or brown parasites that look like poppy seeds, especially before feeding. Before feeding, ticks are minuscule and flat, and they are easily mistaken for poppy seeds based on their dark brown or black appearance. They can also look like bed bugs at first glance because of their size and shape.
"Bedbugs leave behind tiny blood stains or small black dots that look like mold or like black pepper sprinkled in the seams of your mattress or creases in the corners of your sheets," Eric Hoffer, the owner of Hoffer Pest Solutions, told Insider.
