2. Bed Bugs

These creepy crawling little pests will make your skin crawl just thinking about them. They are about the size of an apple seed and a reddish brown.

Check your sheets for blood spots. You should also be careful of any second-hand furniture you decide to buy.

3. Ants

Six different types of ants are commonly found in the United States. While they vary in size and color, they all have one thing in common; they are a nuisance.

4. Wasps and Bees

There is a delicate balance you need to have when it comes to the flying pests around your home. Both bees and wasps provide valuable services. Bees pollinate the local flora. While wasps help control the other insects.

The problem is that wasps tend to become aggressive and territorial. You don’t need wasp guardsmen at your front door preventing people from entering your home.

You will know you have a wasp, bee, yellowjacket, or hornet problem by walking around your home and looking for their nests. They are typically attached to awnings, poles, overhangs, or fences.


The first thing you’ll want to do is remove any available food sources. This could be pet food you left out, picnic scraps, garbage bins, or a compost pile.

Anything sugary can also attract them. So pick up any fruit juice, cans of soda, or fallen fruit around your trees.

If you do notice wasps, avoid trying to swat them. This will trigger a release of their stress hormone and will call the other wasps to the first one’s rescue.
