Bugs, Black Velvet Bugs and Butterflies

Black Velvet Bug

These are the most common of all insects in the home and are found in most homes. They look like tiny black ants with wings and a white tuft on their head. Their wings are actually made up of thousands of tiny hairs that allow them to fly. They can be found on windowsills, inside closets, under sinks and in other dark areas where they can hide during the day. These insects do not bite or sting humans and are not harmful to pets or children. The only way to get rid of these bugs is by using insecticides that are specifically designed for them

Butterflie

Butterflies are beautiful creatures but they have become more difficult to manage because they have become more aggressive over time. This is due to the fact that they like to lay their eggs in homes which makes them very hard to get rid of once they arrive. You should be aware that some butterflies may not look like what you think it should look like because there are hundreds of types of butterflies around the world with different colors, sizes and behaviors
