If you still have native ants, keep doing what you have been doing (or not doing). If you see an invading fire ant mound in an otherwise RIFA-free area, verify that it is not the native species before attempting to kill it. If you do treat such a RIFA mound, be sure to confine treatment to that mound or its immediate surroundings. Many observant folks notice that armadillos dig into fire ant mounds and correctly assume that they are eating the ants.

Along the Nexican border of Texas and in West Texas, there exist native fire ants that are difficult to distinguish from their imported cousins. However, if you can see four tiny teeth on the mandible or jaw of a fire ants, it is S. invicta. Native species possess three teeth. Over East, Central and much of South Texas, the most common native fire ant, S. geminata, can be distinguished without examination of tiny details of anatomy.

Both biological wisdom and recent research indicate that fire ants, like other opportunistic organisms, become more "weedlike" and achieve pest status when introduced into regions free of their natural biological enemies, such as parasites and pathogens. A case in point is the fire ant species native to Texas. Our native fire ant species is a is a minor nuisance at home, but a major pest in India where it was inadvertently introduced.

Other ants compete for food with fire ants and help keep them under control. If you kill all ants in your yard, you create an "ant vacuum" and after the next rain, it will be fire ant queens that land in your "safe" yard to begin new mounds unopposed by any other ants. Fire ants are better at colonizing and dominating newly disturbed habitat than the average ant species.

There is no single, easy answer for every situation. Most people with more than a handful of mounds will be satisfied with just a bait or the "Two Step Method." Remember, no method is 100% effective all the time, though some come close, and no method is permanent. The ants will re­invade, with new colonies probably appearing after the next rain, and certainly within a year.

Some uncertainty comes from the fact that red imported fire ants vary in size (1/16 to almost 1/4 inch long), with the largest workers 2 or 3 times larger than the smallest. Native fire ants are less common in imported fire ant infested areas. Solenopsis geminata is the most common native fire ant species encountered. To the unaided eye, they are almost identical to red imported fire ants. However, S. geminata will have a few larger workers with large, square-shaped heads.

Red imported fire ants are medium-sized ants that build mounds of soft soil. They are rarely larger than 18" in diameter. In cold, dry areas such as the High Plains of Texas, mounds are usually much smaller and harder to detect. When disturbed, fire ants emerge aggressively and sting. Their sting usually leaves a white pustule on the skin. Other small to medium-sized ants that build small mounds will actually run away from disturbances and are not fire ants.

These are not ants, but rather a wingless solitary (non-social) female wasp in the family Multillidae. Females are wingless and typically colorful; males have wings. The common name for the group is "velvet ants." Here in Central Texas we have about 40 species of velvet ants, some small and some big. The "hiss" is called "stridulation" and is caused by washboard-textured body segments rubbing rapidly against one another.

Fire ants reproduce opportunistically when conditions are wet and warm. They are found in all types of soil, but they do better in open pastures and sunny, grassy places than in thick shaded woods. Grassy medians of freeway and mowed pipeline and powerline rights of ways provide prime "freeways" for the ants too. Polygyne colonies (those with multiple queens/mound) can reproduce by budding off new colonies and spread by walking a few meters per year.

Broward County Extension Education Division recommends increasing the composition of native plants in our urban landscape in an effort to make our surroundings more sustainable, conserve water, reduce fertilizer and pesticide runoff and decrease maintenance costs. Increasing the number of native species used in a landscape provides food and shelter for native, desirable wildlife.

Yes. Cocos has these annoying ants, which can inflict a nasty bite. Be very aware of "bare" patches as this is usually an excellent indication that a fire ants nest is there.

Below are categories of frequent questions received by The Road Home. Please choose a category from the list below for questions related to that topic.

Look at the ants. Fire ants include many opportunistic ant species of the genus Solenopsis. There are native and imported species. Native Texas fire ants are very similar to the imported pest, but actually help retard the spread of the imported species and should be spared if possible. Both native and imported fire ants are small, dark orange/brown ants with workers of various sizes that quickly mobilize and sting en mass when their mound is disturbed .

You might have seen pictures of massed fire ants killing hatchling quail chicks or stinging the noses and eyes of newborn deer. Without question RIFA can kill young birds, small mammals, and reptiles. However, in the case of quail, it could be that a more important impact on populations is the removal of insect food that would normally be available to quail chicks.

egg laid by queen 2. larva hatches and grows through 4 larval developmental stages or instars between which molts of larval skin occur 3. at 4th molt a pupa is produced 4. pupa hatched into adult ant. How the colony feeds and cares for female larvae determines their caste; i.e., whether they behave as workers (all are sterile females) or queens. Male ants develop from unfertilized eggs and therefore possess only one set of chromosomes; i.e. they are haploid.

Fire ants are from South America. They entered the U.S. through Mobile, Alabama, probably in soil used for ships' ballasts. They were accidentally introduced around the 1930's and have been spreading since.

There isn't much you can do, except watch the affected area for excessive swelling, itching or redness, or other symptoms like shortness of breath, thickening of the tongue, sweating, etc. that could indicate a systemic allergic reaction. Treat stings as you would stings of other insects and keep them clean and intact to avoid secondary infections.

Laundry piles are convenient places that present lots of tunnels for the ants. Often, reports of ants in laundry occur following a flood or severe drought. Ants are observed in utility rooms, bathrooms or near the water heater where they have access to the area from outside. When it floods they move into any good dark place, but in drought conditions they tend to move to moist areas.

Anyone who has been stung by one or more of these aggressive insects can answer this question. Fire ants clamp onto their targets with powerful jaws and sting their victims repeatedly. Each sting injects a dose of venom that causes a burning sensation. The stings raise itching blisters that can become infected. In sensitive victims, the stings can cause anaphylactic shock (symptoms include trouble breathing and fainting) or even death.

Identifying fire ants is difficult because they look much like ordinary ants. They are 1/8 to 1/4–inch long and reddish brown to black in color. Fire ants are probably best distinguished by their aggressive behavior and characteristic mound–shaped nests.

ANSWER: We often ask, "Can we get rid of ants in our gardens?" We spread ant bait in home made traps. These traps allow ants in but keep water out. We discovered that if we spread ant killer under host plants, irrigation and rain will dissolve the chemical and wash it over the roots. The roots draw up the chemical which will change the taste of the plants. When a female butterfly lands on a leaf (they taste with their feet) they will often lift off and not lay eggs.

The worker ant is very dark brownish almost black and about 5mm long. The queen is rarely seen except for certain months in the summer, is about 15mm long and mid brown in colour.

The emergence of 'flying ants' in large swarms can cause alarm to people but nothing can be done to stop them swarming, and they are also harmless.

Insecticidal dusts are an effective treatment against garden ants and these can be purchased from most hardware stores. Insecticidal aerosols are suitable for crawling ants and can be sprayed into cracks and crevices, you can also treat flying ants with this. Bait formulations rely upon worker ants taking the bait back to the nest sharing it with other ants.
