Crazy Ant
This species may be difficult to control and does not feed much on ant baits. The keys to control are to find the colonies and subcolonies and treat them directly. Regular inspections and service are necessary to find and treat new colonies as they move from neighboring properties. The services of a professional, such as Terminix, are very helpful when encountering these ants. General tips for limiting ant infestations include:
- Eliminating piles of lumber, bricks or other debris that could serve as a nesting site for ants.
- Keeping landscape mulch less than 2 inches thick and at least 12 inches away from foundations.
- Ensuring the sprinkler system does not spray directly onto the foundation.
- Sealing as many cracks in the home's exterior as possible.
- Keeping tree and shrub branches trimmed to prevent touching the home.
- Considering re-landscaping to avoid using plants that are prone to aphids and similar insects. At the very least, treat such plants for aphids regularly. A tree/shrub company, such as TruGreen, can be helpful with this task.

Pavement Ant
Individual pavement colonies can often be controlled using ant baits, but perimeter inspection and treatment are commonly necessary for long-term relief. Pavement ant colonies are controlled by direct treatment of nests in the soil. Where colonies are located under slabs, ant baits may be successful in controlling an infestation. If baits are unsuccessful, the slab may need to be drilled and treated underneath.
These tips will help prevent a pavement ant infestation:
- Seal cracks and holes in the exterior of the home to prevent ants and other pests from entering.
- Keep vegetation cut away from the foundation of the home.
- Avoid using items such as stones and landscape timbers next to the home's foundation. Pavement ants nesting under these items are likely to infest the home.
- Keep layers of mulch in landscape beds less than two inches thick and at least 12 inches away from the foundation.

House Mouse
The best way to avoid invasions of mice is to (1) provide as little harborage as possible that might attract rodents, and (2) seal as many holes and cracks in the outside of the home through which mice might enter. Follow these recommendations to help prevent rodents from seeking the shelter provided by your home:
- Keep firewood stored as far from the home as possible and store it off the ground. During the winter, store only enough wood next to the house to burn every couple of days.
- If possible, remove any piles of debris, stones, bricks, etc. If these are near the foundation of the home they serve as harborages to attract rodents. Once there, it is any easy step for rodents to enter the building itself.
- Do not allow piles of leaves to accumulate next to the home's foundation. This also serves as attractive harborage for rodents - mice in particular.
- Seal any hole or crack larger than 1/4 of an inch. A good rule of thumb is that if a pencil can fit into it, a mouse could too. Large holes or cracks should be stuffed with steel wool or wire mesh before sealing with caulk or foam, otherwise rodents could chew through to enter.
- Install good, thick weather-stripping on the bottom of all doors to prevent rodents from entering. The garage door may prove difficult to seal completely, so the door from the garage to the house must be sealed tightly.
- The installation of one or two wind-up mousetraps in the garage can catch many mice as they enter. These traps can catch up to 15 mice with one setting. Ask your Terminix service professional for more information.
- Remember, your Terminix service includes coverage of commensal rats and mice, and much of the service provided during the colder months is to inspect for signs of rodents and to maintain preventive control measures.

Pack Rat
The best ways to avoid invasions of pack rats are to (1) provide as little harborage as possible that might attract rodents, and (2) seal as many holes and cracks in the outside of the home through which rats might enter. Follow these recommendations to help prevent pack rats from seeking the food and shelter provided by your home:
- Keep firewood stored as far from the home as possible and store it off the ground. During the winter, store only enough wood next to the house to burn every couple of days.
- If possible, remove any piles of debris, stones, bricks, etc. If these are near the foundation of the home they serve as harborages to attract rodents. Once there, it is an easy step for rodents to enter the building itself.
- Seal any hole or crack larger than 1/4 of an inch. Large holes or cracks should be stuffed with steel wool or wire mesh before sealing with caulk or foam, otherwise rodents could chew through to enter.
- Install a good, thick weather-stripping on the bottom of all doors to prevent rodents from entering. The garage door may prove difficult to seal completely, so the door from the garage to the house must be sealed tightly.
- Remember, your Terminix service includes coverage of commensal rats and mice, and much of the service provided during the colder months is to inspect for signs of rodents and to maintain preventive control measures.
Although not a significant health threat, pack rats are associated with a number of diseases that infect humans, including plague and lyme disease. For this reason, dead rats should never be handled using bare hands, and care should be taken to avoid their ectoparasites, especially fleas and ticks.

Africanized Honeybee
Because the Africanized honeybee cannot be distinguished from its native cousins without detailed scientific measurements, any honeybee nest or swarm found in southwestern states should be respected at a safe distance. Only experienced beekeepers and/or pest management professionals should be contacted to deal with colonies or swarms of honeybees. Never attempt to treat such nests without the proper training and equipment.
Once the colony inside a wall or attic has been eliminated, the building owner will need to open the wall and remove all the honey and honeycomb. If not removed, the honey will rot, produce strong odors and seeping stains, and will attract other insect pests.
