However, with a few precautions, it is possible to keep yourself and your loved ones safe.

Set up a barrier for bugs

During summer, your house becomes an exposed environment to flying insects that might carry diseases. Apart from being a nuisance, they can also be a health hazard. You need to stop bugs from entering your house and bringing infections or bacteria. Keep insects away from electric bug zappers from coming and spreading in your entire home.

Cover up exposed skin

During the hot season, it may be difficult to cover your entire body especially when the temperatures are extremely high. However, if you are traveling in areas where insects are prevalent, avoid wearing thin clothing as some insects can easily bite through the fabric. Protecting clothing such as long sleeves, socks, long pants, and hats can protect you from the bites of the disease-carrying bugs.

Check pets before entering the house

Avoid nocturnal outdoor activities

Most insects tend to be more active and bite their hosts during the night. To avoid their bites, it is better to avoid as much as possible to do outdoor activities during dawn.
