Pest Control FAQs, answered by experts

Male carpenter bees actually don't have a stinger, but they will hover around areas as a defense mechanism to deter intruders. However, females can sting but are not typically aggressive and tend to only sting when threatened or provoked. They are less active at night, so you are less likely to encounter them because they tend to rest at night.

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).

Flea eggs can’t take heat, so use that information to your advantage. Take any affected clothes and linens and wash them on a hot setting (140℉ or higher) to kill them off. You can also rid carpets and furniture using heat. After vacuuming all surfaces thoroughly, use a steam mop or cleaner to get rid of the remaining flea eggs and residue. 

Flea eggs also can’t handle extreme cold. You could seal affected linens and store them in a freezer. 

It’s normal to spot the occasional ant roaming your house, but if you’ve applied DIY treatments that don’t eradicate the problem, you should consider hiring a professional ant removal service. You should also be concerned about an ant infestation when these pests cause structural damage to your home by tunneling into wood features.

Rats have a strong sense of smell and do not like the smell of bleach. However, pouring bleach in drains or toilets is not a good idea because it can cause dangerous chemical reactions and even damage your pipes. It’s best to have a professional plumber install a rat-blocker or non-return valve instead to keep critters from crawling up the toilet.
