How do mosquitoes develop?
First, it is important to understand mosquito biology. Mosquitoes are small flies that lay their eggs in, on, or near stagnant water. The larvae, or wigglers that hatch from the eggs live in water and feed on organic debris until they transform into a motile pupa, or tumbler, and finally into the familiar adults. This process, from egg to adult, requires as little as one week when conditions are favorable. Emerging females...

A bed bug check takes only a few minutes to complete and can give you and your family peace of mind when staying at new places.
Bed bugs are small insects, but big enough to see with the naked eye. They are oval shaped, wingless, and reddish brown. Bed bugs feed only on human blood, usually at nighttime while we are sleeping.
It's important to remember that bed bugs can occur anywhere and are not always an indication of poor hygiene or care. Bed bugs can be moved to new places on furniture, luggage,...
