While bed bugs haven't been shown to carry disease, according to the EPA these pests leave small bite marks across the body that, in rare cases, can cause an allergic reaction. Depending on the individual, these bite marks can become inflamed or even cause a whole-body reaction from a single bite. These extreme cases warrant immediate medical attention.
Costs in dealing with these little critters can be sizable. Treatment can be upwards of a few thousand dollars for a single room. That doesn't take into consideration the cost of a lost customer, damage to an inn's reputation, or refunds. In order to be prepared, it's important to educate yourself and your staff.
