Termites, carpenter ants, and wood-boring beetles can move from wood furniture to other areas of your home. If you notice signs of bugs in wood furniture, it's best to remove and isolate it for treatment. Remember that it can be difficult to identify which type of pest you are dealing with, and they can already be in areas of your home.

If DIY methods don’t work or you don’t know which pest it is you should contact an exterminator if you are showing signs of wood-eating pests to prevent further damage.

If you spot two or more cockroaches inside your home, you should hire an exterminator to conduct an inspection and provide eradication treatments. If you see one cockroach and no others, it may have been a stray that wandered inside. Don’t hesitate to call an exterminator as soon as you see more than one cockroach in your home.

While possums don’t typically carry rabies, they can have lice, fleas, ticks, and mites. According to the University of California’s Pest Management Program, possums can also carry diseases like leptospirosis, tuberculosis, toxoplasmosis, coccidiosis, and fevers. Possums are also the carriers of a parasite that can pass to horses and cats called Equine Protozoal Myeloencephalitis (EPM).

Stink bugs don't harm humans or their homes, but they can do a number on vegetable crops, especially in large numbers.
