Termites are notorious for causing extensive damage to wooden structures. They live in colonies and feed on cellulose materials like wood and paper. Identifying termites can be difficult as they usually remain hidden within walls, floors, or foundations. However, mud tubes, discarded wings, and hollow-sounding wood are common signs of a termite infestation.

Ants are social insects that often invade our homes in search of food and water. They come in various species, such as carpenter ants, pavement ants, and pharaoh ants. Ants can be identified by their segmented bodies, elbowed antennae, and narrow waists. They leave visible trails of pheromones and often build nests in walls, under floors, or in outdoor areas near the house.

4. Bed Bugs

Bed bugs are small, reddish-brown insects that feed on human blood. They are often found in mattresses, bed frames, and furniture near sleeping areas. Bed bugs leave behind itchy bite marks in a linear pattern on the skin. Other signs of their presence include blood stains on sheets, dark spots of excrement, and a sweet, musty odor.

Mosquitoes are irritating pests known for their itchy bites and ability to transmit diseases such as dengue fever and malaria. These flying insects are most active during dusk and dawn. Female mosquitoes require blood to lay eggs and are attracted to humans by body heat and carbon dioxide. Eliminating stagnant water sources and using protective measures like mosquito nets and repellents can help prevent mosquito infestations.

Spiders are often unwelcome visitors in households, although most species are harmless and even beneficial as they prey on other pests. However, certain spiders like the black widow or brown recluse can be venomous and pose health risks. Spiders have two body segments and eight legs. Their webs and egg sacs are visible signs of their presence.
