Keeping Ants Under Control

Besides using pesticides and ant baits, there are other small ways in which you can keep creepy crawlies out of your home and yard. Tidiness in the home and garden play a vital role in ant control.

Let’s go over a few tips!

  1. Keep food scraps off of your kitchen floor and patios. Worker ants (or the ants that bring food back to the colony) are attracted to leftover food sources. Cleaning your kitchen floor and vacuuming weekly can help to pick up any crumbs that you may have missed during dinner. Be sure to also sweep your patios, decks, and porches for food crumbs to keep ants from wandering near your outdoor lounge area.
  2. Avoid leaving water out. Like every living creature, ants need water and food. Outdoor water dishes for pets or any other standing water source can attract ants, especially during the hotter months when the water supply is shortened.
  3. Use sealants. Ants are tiny bugs that can get in through practically any opening. It’s a good idea to seal in cracks around windows, doors, sinks, bathtubs, and anywhere else you think ants may enter through.
  4. Stack some firewood far away from the house. Ants love firewood. Firewood makes a great hiding place for ants. Stacking firewood on the edge of your property is a wonderful way to deter them from your home and outdoor seating or play areas.
  5. Trim back vegetation that is near your home or structures. Ants make their way into homes and buildings largely by crawling on bushes or trees onto roofs or window sills. Avoid these unwelcome guests by trimming away branches.
  6. Correct moisture problems in the home. As we mentioned previously, ants are attracted to water and moisture. Be sure to check under your sinks and in the bathrooms for moisture buildup, as well as pipes for leaks.

Identifying Your Ants

If you’re not too sure which type of ants you’re dealing with, you’re in luck. Because in this section, we’ll be going over some of the most common home and yard ants.

Fire Ants

If you’re a southerner, you’re probably all too familiar with Fire Ants. Fire Ants love hot weather and generally are out and about when it’s the mid-70s to 95 degrees.

They’re incredibly aggressive ants whos stings burn like… well… fire. Fire Ants are bright to deep red in color and about 1/4 of an inch in length. They like to make dirt mounds in very sunny, flat, open areas such as playgrounds or near sidewalks. So don’t expect to find these guys in shady or damp places.

Fire Ants are omnivorous and will eat anything they can get their sticky little fingers on, including sugary foods, meats, and even vegetables.

Carpenter Ants

Apparent by their name, Carpenter Ants tunnel through wooden beams to make their nests. They can wreak havoc on homes with exposed wood and house approximately 50,000 of their ant pals in your walls (per colony).

They’re usually dark red or black in color and around half of an inch long. They can be found in dead trees and damaged wooden structures.

Crazy Ants

About 1/8 of an inch long, Crazy Ants are most commonly identified by their “crazy” or erratic movements. They can be yellowish, black, or raspberry in color and most often have long legs that are disproportionate to their tiny bodies.

These ants tend to wreak havoc on electrical wires and like to nest in moist areas. Crazy Ants will feast on practically anything, including sweets, so don’t be surprised if you find these in your kitchen. They also like meats and other insects as snacks.

Odorous House Ants

These ants are most commonly found in kitchens on countertops or near sugary foods. They’re usually black or dark brown in color and give off an unappetizing smell when crushed. Odorous House Ants are very tiny and fast, often moving swiftly along kitchen floors after heavy rains.

They’re only about 1/8 of an inch long and usually travel in large lines of their ant family.

FAQ

Q: Will ant killers work on all ants or just specific ones?

A: Generally, ant killers will work for any of your average yard or home ants. Some ant killers may specify, but you can more than likely use those for any type of ant also.

Q: Can ants learn to avoid ant killers and baits?

A: No. Ant killers are mostly applied directly to the ant mounds so the ants come in direct contact with the poison, and baits will not lose their attractiveness to ants.

If you notice that ants are beginning to avoid your ant bait, it’s most likely because the pheromone trail of other ants has worn away, thus keeping new ants from traveling near the bait. Try moving the bait to a different location.

Q: I have ants in the bedrooms. Should I place ant bait in the rooms or elsewhere?

A: You can place ant baits in bedrooms. Terro Liquid Ant Bait is made with sugar, water, and borax, making it safe to have around your family and in your home (when used as directed). However, we do recommend that you keep any ant killer product out of a child’s or curious pet’s reach.

Q: How long does ant killer take to work?

A: Depending on what type of ant killer you purchase, they usually take around 48 hours to kill ants.

Q: Will ant baits and killers damage my wooden floors or carpet when used indoors?
A: Indoor ant killers will usually have cleaning instructions in the event of spills or temporary staining. Most of the time, indoor ant killers will not damage any type of flooring.
Q: Will ant killer hurt my grass?
A: All of the ant killers on our list most likely won’t harm your grass when used as directed. However, keep in mind that ant killers are meant to be placed directly on mounds or placed near ant trails. We recommend that you avoid placing any ant killer in unnecessary outdoor areas to keep from potentially killing the grass or other vegetation.
Q: Do liquid ant killers dry clear?
A: Yes. You can expect any liquid ant killer you purchase to dry clear. However, if used indoors, particularly on the carpet, liquid ant killers can attract dust and dirt. This may result in a slight color.
Q: Can ant killers be used in cars? 
A: They can be. Natural liquid spray ant killers would be your best (and safer) bet. We recommend letting the solution gas off for a few days after application before you drive the car anywhere.
