Known as one of the toughest pests to defeat, cockroaches are winged insects that can carry disease, cause allergic reactions, and taint food with bacteria.

They love moist areas and are drawn to food that’s been left out so hygiene is important in getting rid of them.
To kill cockroaches, the most popular approach is with bait which they then take back to their nest and share with others, effectively killing them all.

Ants can be stubborn when it comes to pest control and you will need to work for a few months in order to eliminate them.
However, there are many proven methods for getting rid of them including insect sprays, ultrasonic repellents, and baits and poisons and that ants take back to their colonies.
Although not all spiders are considered dangerous, they do attract other pests in the home and can also cause allergies with their webs.
They’re able to multiply quite quickly, depending on the species, and will be more prevalent in certain seasons of the year.
Some spiders can be fatal or poisonous especially for children and animals who don’t understand the risks they pose, so they’re not a pest you want to leave hanging around.
The most common approach to getting rid of spiders is using insect repellent or spray, and they will require more than one treatment usually to be effective.

In some cases, you may need to completely discard your bedding and have your mattresses treated with heat and chemicals in order to remove the bugs.
Fleas are winged insects that jump, and they’re commonly found in homes that have either cats or dogs as pets.
Although they do also bite humans, their main hosts are animals and they are capable of reproducing at a fast rate.
The average flea life cycle takes between three to six weeks to complete which is what makes them such a stubborn pest.
A flea infestation will usually take multiple treatments to deal with due to the number of eggs that can spread throughout the house.
Common flea treatments include sprays, fumigation, and heat treatments. Regular washing of pets with specialized flea shampoo is needed and all furniture and bedding have to be treated in order to get rid of them.
Ticks are parasites that attach themselves to the skin of animals and feed on their blood.
They pose a serious threat to both humans and pets, and an infestation usually begins outside of the home but can make its way inside.
Ticks can spread disease like Lyme disease and cause paralysis so it’s imperative to treat this pest as soon as it’s found.
Unlike fleas, ticks can’t jump so it can be harder for them to find a host and they are usually more of a problem outside than inside.

The most common methods for treating wood-boring beetles include natural repellents and sprays, and a solution of diatomaceous earth which is a desiccant that kills larvae and beetles.
For more serious cases where these beetles have completely taken over a home, it may be necessary for complete fumigation which involves suffocating the pests with help from a professional exterminator.

Termites are especially attracted to wood and can quickly eat through timber, trees, and plants.
To rid yourself of a termite infestation usually takes a lot of time, and can be over 12 months in some cases.
Where an infestation has begun a long time ago, like in older homes, it can be especially hard to get rid of them and so in-depth fumigation might be needed.
Otherwise, bait stations and poison may be sufficient to kill them when their numbers are still low.
Houseflies and fruit flies are the two most common species known as pests in the average household.
Fruit flies will quickly and easily destroy food that’s left out and can pose a threat to your outside garden.
Common houseflies are capable of carrying bacteria and disease, so they present a completely different type of problem as a household pest.
To rid your home of flies is relatively easy and most of the time they can be caught with a trap or repelled with natural products.
