• Absolutely love using Responsible Pest Services. My favorite part of the service is that we receive emails confirming the date for our service. This is of great help so we can ensure that our pets are inside. Also, we can add special notes for the service agent so that we make sure he checks some tough to see/reach area.

  • The technician arrived promptly on time, was very friendly and professional, described in detail the services to be performed, and even noticed I had pets and talked about the safety of the products without me having to ask. I was pleasantly surprised by the extent of the detail-oriented service!

  • The spiders seem to have fled from our front and back yards. All in all, we are quite pleased with Responsible Pest Control. We will use them again.

  • Moved to Responsible from Clark, I felt Clark was “checking a box” and getting paid. Not the case with Responsible Pest Services, they take time to do a complete job. I’ve had no ant issues since we started using them, and the ants are the worst in the winter. If you are with somebody else consider a move to Responsible.

Odorous House Ant – The odorous house ant is about 1/8″ and dark brown in color. It gets its name because when crushed the workers give off a rotten coconut odor. These ants normally nest outdoors under items on the ground, within landscape mulch, beneath loose bark on trees, under ground cover, in potted plants and other suitable voids They are often found invading and nesting in homes. Odorous house ants may develop huge colonies containing thousands of workers and numerous queens making this species very difficult to control.

Argentine House Ant – The argentine ant is light to dark brown measuring 1/10″. This ant is readily adaptable and can nest in a great variety of situations. Colonies are massive, and may contain hundreds of queens. Their nests are usually located in moist soil, along sidewalks, or beneath boards. They often invade residential and commercial buildings in search of food and/or shelter. They travel in trails and forage day and night. The ant can eat almost anything but prefers sweets. It has no important natural enemy in the United States.

Pharaoh Ant – The pharaoh ant is extremely small, measuring about 1/16″ in length. It is light yellow to reddish brown in color. This ant is a serious nuisance in hospitals, rest homes, apartment dwellings, hotels, grocery stores, food establishments, and homes. They feed on jellies, honey, shortening, peanut butter, corn syrup, fruit juices, soft drinks, greases, dead insects and even shoe polish. They have been found in surgical wounds, I.V. glucose solutions and sealed packs of sterile dressing in hospitals. The pharaoh ant is capable of mechanically transmitting diseases.

Fire Ant -Fire ants are reddish brown and found in many sizes ranging from 1/8″ to almost 3/8″. Fire ants pose a health risk to anyone venturing into areas where the ants are found. These ants nest in the soil and construct large mounds that are easily seen in lawns and pastures. The fire ant is a veracious stinger, and while most stings result only in a raised welt, a person allergic to insect stings could experience a more serious reaction. Additionally, a person seldom receives just one sting. Rather, dozens or even hundreds of stings can be inflicted quickly on a person accidentally kneeling or standing next to or on a fire ant mound.
