The threat of termites on homes

Termites are the leading enemies of homeowners. It doesn’t spare any property, be it new homes or old ones. Worse, the infestation goes unnoticed for months until the signs of damage become noticeable.

However, some homeowners often dismiss the tell-tale signs of the infestation. This will lead to further damages and costly repairs, not to mention the cost of treatment.

To give you an idea, the following are some of the damages termites alone can do to your home:

-Wood damage

Termites eat wood 24/7. Also, they eat the same amount of wood in winter as they’d do in other seasons. In fact, the pest can consume a 2” x 4” piece of wood in six months. However, an expansive colony and the Formosan species can consume this faster at a span of 25 days.

Such wood damage is appalling, especially for new homes. If you don’t address the termite infestation, you’ll have to deal with the next possible damage.

-Compromised structural integrity

A massive colony can impact the structural integrity of a house. This is very much evident for old homes with no occupants. Since the termites are undisturbed, they can proliferate fast. Soon enough, they can eat the foundation enough to lose its strength.

Aside from the foundations, termites can also take down wooden beams on your attic and flooring. All of these will require expensive and immediate repairs. Aside from that, you’d have to shell out more money for the termite infestation. Just so you know, standard homeowner’s insurance doesn’t answer to termite infestations.

-Potential allergies

Although rare, an advanced termite infestation can trigger allergies and asthma attacks. This is mainly associated with the frass or droppings that pest leaves as the by-product of their wood-chomping nature.

Also, the discarded wings and molted skin can also cause sensitivities.

-Decreased house market value

For those who are planning to sell their homes, a termite infestation will directly impact its market value. Worse, you won’t be allowed to sell it unless you’ve fixed the termite issue.

Treating the infestation will cost more money. As much as you can sell your home as-is to cash for home buyers, you won’t get the best value from your property.

Common types of termites found in residential areas

There are more than 2,000 termite species all over the world. Of that number, about 45 species and subspecies can be found in the U.S. Nevertheless, four main species infests homes. These are the Subterranean, Drywood, Dampwood, and Formosan termites.

-Subterranean termites

Subterranean termites are soil-burrowing species that will form mud tubes to infiltrate structures. Also, they will build an underground network with intricate sacs and divisions that can span for up to 20-feet deep. Also, they will build soil mounds outdoors as an extension of their harborage.

These mites have a creamy white color and can grow by up to 1/8” long. Although small, they create the largest pest nest and they can be found in all U.S. states except Alaska.

These termites need to stay within their mud tubes and harborage to survive. If they got exposed outside of their tubes, their bodies would dry, which will lead to their death.

Take note that Subterranean termites are responsible for most of the termite damage in the whole country.

-Drywood termites

On the other hand, Drywood termites prefer dry wood and hotter environments. They are usually found on wooden floors, house foundations, and dead trees.

Moreover, Drywood termites don’t need contact with the soil, so their infestation goes unnoticed for an extended period. But unlike Subterranean termites, they are larger and can grow between 3/8” and 1 inch. Also, they have smaller mandibles.

Meanwhile, Drywood termites build smaller colonies and they are typically found in southern states as well as the west coast of California.

-Dampwood termites

The opposite of Drywood, Dampwood termites require moisture to survive. Still, they don’t require soil contact and they rarely invade homes. Usually, they will feed on trees and other live wood with high moisture content.

With this nature, Dampwood termites are typically found in coastal areas along Florida and nearby communities. Also, they thrive on semi-arid areas.

Moreover, Dampwood termites share the same large mandible as Subterranean species. However, the latter has a lighter color, while Dampwood is darker.

-Formosan termites

Lastly, we have Formosan termites. Of all the termite species, Formosan is considered as the most destructive. Also, once its colony infested a structure, it would be difficult to control.

Formosan termites are aggressive and voracious wood eaters. Usually, they will grow for up to half an inch and can eat wood without being detected for several months.

Nevertheless, Formosan termites are rarely seen in most states. They are recorded in several southern states like Alabama, Florida, Tennessee, South Carolina, Texas, and more.

Signs that your home has a termite infestation

Do you suspect that your home is infested with termites? You should look for the following signs:

-Mud tubes
-Frass or droppings
-Discarded wings
-Spongy wood
-Ticking sound inside the wood
-Flying “ants”

Take note that a termite infestation may go unnoticed for a few months. When you saw spongy wood in your home, the termites may have advanced its infestation.

Upon the discovery of the pest, you can perform DIY pest control as long as the infestation is still in its infancy. Below, we’ve reviewed three of the best termite killer spray options that you can try.

However, if the infestation is already massive, we suggest that you call an exterminator to assess the situation. You can still use termite sprays, but only after professional treatment has been done.

What to do when you discover termites in your home

What if you discovered an infestation in your home? Before you panic, we suggest that you do the following first. Take note that some of these may or may not apply depending on the situation.

-Don’t disturb their harborage

Most homeowners who encounter a termite infestation for the first time tend to disrupt the termite harborage as an effort to control its population. As much as this is a satisfying move, it will also make the condition worse.

What will happen is that the termites will just transfer to a different spot in your home. This makes diagnosis more difficult.

-Don’t give furniture away

Upon the discovery of the infestation, avoid giving away any wooden furniture. Although this won’t fix the pest problem, it will stop its spread on other households.

Just the same, avoid bringing hand-me-down furniture on your home to prevent another infestation.

-Call a termite exterminator

For those who want a thorough termite inspection and treatment, professional exterminators are unbeatable. They can tell you what species is infesting your home and the extent of the infestation.

If the infestation is isolated, you can use termite sprays to fix the infestation. Take note that this is ideal for controlling the population. If the termites persist, you should call pest control experts.

-Try using DIY solutions

If the termite infestation is still small, you can use the best termite killer spray. These household products are diluted versions of commercial termiticides that exterminators use. Depending on the formula, it can contain cyfluthrin, fipronil, imidacloprid, hexaflumuron, and more.

Moreover, termite sprays are contained in aerosol cans for easier application. Some, like the TERRO spray (review below), would have a dual-action spray that lets you apply it into small wall openings and crevices.
