Ant invasions and why they happen

A story broadcast on San Diego’s CBS8 channel recently covered an issue that was causing locals to call their area pest control services. The problem: ant invasions. People in San Diego County have been seeing more and more invasions into their homes this summer and according to a news release published by the Standford News Service, the school released a study that found there was a strong relationship between the weather and infestation.

In order to find the link between the two occurrences, Deborah M. Gordon, an associate professor of biological sciences, led a team of Stanford researchers, who surveyed 69 homes in the Silicon Valley area of California between 1998 and 1999. Once a week, participants of the study were asked to monitor and report an estimated number of how many ants invaded their home. They also were asked to report whether they had used any pesticides to get rid of the ants.

Simultaneously, Gordon and her team members documented weekly temperature and rainfall data at weather stations in the area to compare to the reports from participants of the study.


While some of the products reduced the number of ants, none effectively prevented invasions. Sprays got rid of the most ants, followed by household cleaners and baits, and herbal and natural products were the least effective.

“Our goal was to determine if there really is an association between ant invasions and weather,” Gordon stated in the release. “And if so, does pesticide use affect the intensity of infestation?”

The reports from the study showed that a number of products were used in an attempt to rid the homes of ants including:

• “Cleansers, such as bleach, ammonia, soap, Windex and Formula 409;
• Herbal and natural products, including hot pepper, chili oil, lemon and vinegar;
• Sprays, such as Raid, Black Flag and Hot Shot;
• Baits and traps, including Combat, Grant’s and Ortho Ant Kill.”

Ultimately, ants will likely invade homes during cold and wet conditions, usually during winter months. The study found a smaller peak occurs in hot and dry conditions, around August and September.

“When you don’t have ants in your house, putting out pesticides won’t make any difference,” Gordon stated. “The most reliable cause of a decline in infestation may be a change in the weather. They come in because of the weather, and they go out because of the weather.”

Can you really control Mosquitoes and Ticks in Fredericksburg, Virginia?

The scene is nothing new. A family enjoying a warm spring or summer night in their backyard. Dad is flipping some burgers, sipping on a cold one, while chatting with the neighbor. Mom, the neighbor’s wife, and the kids are all sitting on the patio. They have the citronella torches lit, Son just cut the grass, and you’ve all covered yourself in DEET. The trepidation builds with every burger Dad flips…

“SWACK” one of the ladies has just slapped their neck.

“OH NO,” Dad says to himself, knowing it has begun.

Within mere minutes everyone is swatting, slapping, shuffling, scratching, and everything else possible to alleviate the growing irritation of the mosquitoes.

The neighbor speaks up sheepishly. “Maybe we should all go to Ted’s house. They never seem to have mosquitoes bothering them”


“How is that possible” Dad asks. He then looks over at Ted’s yard where he and his wife Martha have just turned on their porch lights and were settled in with cool drinks on their hammocks. Smiling comfortably, they were the envy of the neighbors.

A sign in their front yard catches Dad’s eye…

against them allowing them to attach. This method of finding a host is what allows the same treatment, which makes all potential harborages for both species, effective in protecting your family.

Dad takes not of the number and promises his family this will be the last party ruined by mosquitoes. Jack, the family dog raises his eyes

“Yes, Jack… And Ticks too!” Mom quips as the family laughs

Is it realistic to control Mosquitoes and Ticks in Fredericksburg, VA?



Mosquitoes are not strong flyers at all. In fact, they need to land as rest approximately every 10 feet. Where do they prefer to rest? On the undersides of vegetation that shields them from the sun and holds the most moisture. Why does this matter? It matters because understanding the biology, habits, habitat, and other entomologically pertinent facts is what allows the experts of Sigma Pest Control to conquer these pests and protect your family.

But what about ticks?

Ticks do not travel long distances on their own. They are an ectoparasite that requires a host for all levels of survival. Ticks in your yard are in search of a host. They find a host by climbing vegetation anywhere from several inches, to several feet and wait for a host to brush

Unlike other bugs, you can’t wait until you see a problem to address it, because by then it can be too late!

What's the big deal with termites in Fredericksburg?

termitesWhy are termites such a threat to our homes? Because termites need a few things in life: food, moisture, shelter, proper temperature. Guess which of these our homes provide… That’s right, all of them! Our homes are built of soft, pulpy woods (Spruce, Pine, Fir) that is LITERALLY their favorite entrée! This matters because it allows them to build hydrated mud tunnels that protect them from predators, light, air, heat, cold… it pretty much makes them the safest they could possibly be. Oh, and the interior of our walls pretty much gives them the perfect climate year-round. Pretty much we couldn’t have built them a more perfect paradise if they had ordered it themselves.
