Pest Control FAQs, answered by experts

Rat poison that contains an anticoagulant like warfarin can cause bleeding, chills, confusion, extreme fatigue, headache, convulsions, lightheadedness, and seizures. Anticoagulants prevent your blood from forming clots, which can result in uncontrolled bleeding both internally and externally. Other types of rat poison that aren't anticoagulants attack your liver, kidneys, and digestive system. They can suppress your breathing and heart rate, causing low blood oxygen and poor circulation. Burning in your throat and gastric discomfort are common symptoms.

While water bugs are considered generally harmless to humans, they can bite humans if threatened. Cockroaches are often incorrectly mistaken for water bugs. In this case, cockroaches can bite but are unlikely to bite humans. 

Water bug bites can be very painful and cause symptoms such as redness, swelling, and allergic reaction. Bites will usually heal on their own. However, if you experience severe symptoms or an allergic reaction, seek medical help immediately.

Exterminators use residual insecticides in either liquid or powder form to kill scorpions. These insecticides are applied directly to visible scorpions and their common hideouts and entryways in a home to kill them and prevent future infestation. Exterminators will also use diatomaceous earth at entryways to slowly kill scorpions that enter a home later.

For years, it was believed that hobo spider bites were incredibly dangerous, causing flesh-eating wounds. But the rumors of their bites were greatly exaggerated, and there's been no real evidence showing a connection between a hobo spider bite and necrotizing wounds. 

That said, the spiders can and do bite, usually as a defense response. They won't attack you unprovoked, but if you take them by surprise and get close enough, they may bite you. Their bites may cause some minor irritation or itchiness. 

Maintaining a clean environment can deter spiders to a certain extent by removing clutter and reducing the number of insects they prey on. Spiders tend to favor secluded spots to spin their webs and hunt for prey, and regular cleaning practices such as dusting, vacuuming, and decluttering can disrupt these ideal conditions. Despite these preventive measures, some spider species are highly adaptable and may still infiltrate your home despite your best efforts to maintain a tidy living space.
