Ants are one of the most widespread and challenging household pests. They are incredibly adaptable, social creatures that live in colonies that can range from a few thousand to many millions of individuals. As such, simply eliminating one or two ants will usually not do the job when it comes to getting rid of an ant infestation.

To successfully remove ants from your home, you must first identify the species and determine their specific nesting location. Then, a combination of different strategies should be employed to ensure their complete removal. Strategies can include using ant bait or professional ant control treatments such as liquid insecticides, dust, aerosol sprays, foam applications, and granular treatments applied to areas where ants have been seen entering your home.

Some of the most challenging ant species to get rid of include carpenter ants, odorous house ants, and fire ants; however, no matter what type you have in your home it is important to act quickly and remain vigilant while taking all necessary steps for total elimination — creating an environment uninhabitable for these common household pests.

If you are not sure where to start, hiring professionals is always a good idea for pest control. Make sure to read reviews of different companies to get a better picture of how much does pest control cost and which service is right for your problem.

2. Cockroaches

Cockroaches are a particularly difficult house pest to manage and can be a nightmare for homeowners. They are nocturnal, highly mobile, and can spread diseases and contaminate food with their waste products. They often create large infestations in just a few months, making a small problem turn out of control quickly.

Besides the foul odor they spread throughout homes, cockroaches are known to trigger allergies and aggravate asthma symptoms in those who are sensitive. A single female cockroach can lay up to 40 eggs at once which increases the population rapidly if left unmanaged. Removal of adult roaches is important as well as control of their food sources and harborage areas; removing debris or clutter like paper material or blankets that provide these pests hiding spots will help reduce populations.

In addition, products like baits, gels, traps, or aerosols may be recommended by your local pest management professional to reduce the risk of an infestation before it becomes too much of a problem. Keeping food in sealed containers, disposing of garbage regularly, sealing cracks around doors or windows, and eliminating where possible moisture sources such as leaky pipes may also help reduce roach numbers around your home.

3. Fleas

Fleas are one of the most difficult household pests to get rid of, due to their highly adapted ability to survive. They travel from host to host and can burrow down deep into carpets and furniture, so vacuuming up the surface isn’t enough. In some cases, large-scale treatments may have to be carried out by a professional pest control expert.

Heat treatment is the most effective way of eliminating fleas in a house or building as only high temperatures that exceed 120F/48C can kill them in earnest. Flea foggers will help but must be used with caution as they release potentially hazardous chemicals into the environment.

4. Bed Bugs

They are small (about the size of an apple seed) and can hide in even the smallest crevices. Their flat bodies allow them to slip between mattress seams, cracks in furniture, and other tight spaces. Bed bugs reproduce quickly, with each female capable of laying hundreds of eggs during her lifetime. This means that removing just a few bed bugs does not guarantee their elimination; comprehensive pest control measures must be taken to identify and fully eradicate them.

To successfully remove bedbugs from a home requires a thorough inspection by an experienced professional, like those from Aptive Pest Control. Such experts possess the necessary training to locate harborage areas, followed by elimination using both chemical treatment protocols and mechanical means such as vacuuming and steaming surfaces. Effective control may require several visits over an extended period of time to ensure the complete eradication of these difficult pests.

5. Mice and Rats

The best way to get rid of mice and rats is through the use of traps and bait. Traps come in several different styles ranging from snap traps, glue traps, electronic traps, live traps, live box traps, repeat pest killers, injectors as well as bait stations which are more convenient than sprays. When used correctly they can help reduce the population size significantly in a relatively short amount of time.

Baiting is also an effective approach in controlling a mouse or rat infestation however it requires setting out dozens of small placements strategically around infested areas which adds complexity and initial setup costs. When applying rodent bait be sure not to place too much bait out at one time as this could cause them to overfeed in one area; instead concentration should be made on setting out multiple smaller placements throughout all areas believed to have been affected by rodent activity.

Baits vary in toxicity levels so please consult with your local pest control professional for specific advice about what works best for your application prior to attempting any treatments on your own. Being able to manage an infestation of mice or rats can be a godsend when trying to get rid of raccoons or other large pests too, as they’re often drawn to the smell of smaller animals feeding.

6. Stinging Insects

Stinging insects, such as yellow jackets, wasps, and hornets, can be among the hardest pests to eliminate from a household. Not only are these insects formidable opponents when disturbed or threatened, but they have the ability to reproduce quickly and can establish large colonies with extensive nest structures.

Depending on the species of stinging insect, nests may be found anywhere in the yard and near a structure occupied by humans. It is important to approach stinging insect nests with caution to avoid being stung. Professional pest control services may be necessary when dealing with some species of stinging insects that are difficult to get rid of.


With the right approach and a little patience, most household pests can be dealt with in a safe, effective manner. It’s important to remember that even the hardest pests, such as rodents and cockroaches, can be exterminated using the appropriate methods.

The best way to get rid of any pest is by understanding its behavior and identifying its weakness. That way you can target the problem with an appropriate solution and get rid of these pests for good. Seek help from professionals if necessary, as they have the necessary resources and expertise to eradicate problem pests quickly and effectively.
