When to Call an Exterminator

A pest infestation doesn’t necessarily mean you have to call an exterminator. Pest control products are widely available for purchase and can be used to trap and/or kill almost every conceivable household pest.

However, professional pest control services exist for a reason, namely that some infestations are too large or widespread to deal with alone. So, how do you know when it’s time to call an exterminator?

Can infestations go away on their own?

Infestations rarely go away by themselves. Pests will invade your house because it provides them food, shelter, and water and, once they get comfy, they’re unlikely to leave without encouragement.

If you notice large numbers of bugs or rodents around your home, you’ll need to take action immediately to prevent the problem from getting worse. If your infestation is already well-established, you may need to enlist the help of a professional exterminator.

When should you hire a professional?

When to call an exterminator for mice


Rats and mice are both common household pests, and can often be dealt with using traps and poison baits. But when do you need to call an exterminator for mice?

  • You have recurrent rodent infestations

If your war on mice is never-ending, you need to find the root cause of your recurrent infestations. A pest control professional will be able to quickly pinpoint the problem and deal with it effectively, getting rid of current infestations and preventing future ones.

  • Mice are damaging your possessions

Mice gnaw on everything and can chew through wood, books, clothing, food supplies, and other household items. The only way to minimize the damage is to eradicate the infestation ASAP, and the quickest way to do so is with the help of an exterminator.

  • Mice are getting into your food

Mice carry all sorts of bacteria and can contaminate food stores. Rodents can transmit a wide range of diseases to humans so, if you’re worried about your health, call a professional to get rid of them quickly.

When to call an exterminator for fleas


Fleas can hop into your home through open doors and windows but are more often carried in by pet dogs and cats. Using a regular flea treatment on your pet may be enough to keep them out of your house, but when should you call for expert help?

  • Your flea infestation is large and widespread

Fleas can be difficult to get rid of, especially if they spread throughout your whole house. DIY flea control can be costly and time-consuming, and the quickest and easiest way to get rid of them is with the help of an exterminator.

  • You have recurrent problems with fleas

If you have a recurrent problem with fleas, this may indicate that you have a large flea population outside your house. In this case, you will need to treat your backyard for fleas and may need to call on a professional.

When to call an exterminator for ants


In most cases, ants come indoors when they find a food source. Infestations can often be swiftly dealt with by removing that food source and cleaning up ant trails but, occasionally, an exterminator may be required.

  • You have carpenter ants

Carpenter ants hollow out wooden structures to make their nests and can cause extensive damage to your property. If you have carpenter ants, you need to remove them as soon as possible to avoid a hefty repair bill.

  • You have recurrent ant infestations

If your ant eradication efforts simply aren’t working, you may need to call an exterminator to get to the root of the problem.

When to call an exterminator for roaches


Cockroaches are a very common household pest, so there are lots of resources available for getting rid of them. A cockroach infestation can be cleared using poison baits, but these fast-breeding bugs can be difficult to eradicate without professional help. You should call an exterminator for roaches if:

  • You see cockroaches during the day

Cockroaches are typically nocturnal, and will only venture out in daylight if they have been crowded out of their hiding place. Seeing cockroaches in the day is a sign of a heavy infestation which may be difficult to eradicate without professional help.

  • Your infestation is large and widespread

Roaches breed very quickly and a large, widespread colony can be difficult to get rid of. If your roach infestation has become overwhelmingly large, call an exterminator.

  • Your previous eradication efforts haven’t worked

If you’re losing the battle on roaches, it may be time to call a pest control professional. Cockroaches can cause a number of serious health problems in humans, so infestations need to be dealt with as soon as possible.

Other reasons to call an exterminator

You hate bugs

If insects and other pests make your skin crawl, the last thing you’ll want to do is clear the infestation yourself. Exterminators have strong stomachs and can rid your home of pests without any need for your involvement.

You don’t have the time

Putting together an effective pest control strategy can be time-consuming. If you’re simply too busy to spend hours tracking bugs, laying baits, and cleaning up their corpses, you should outsource the task to a professional.

You want the problem dealt with swiftly

If you’re an amateur pest killer, it may take a little trial and error to work out the most effective way of getting rid of them. If you want them gone immediately, it’s better to hire someone with the tools and expertise to get the job done quickly.


Pest control is often a DIY job, and traps, poisons, and repellents are widely available for purchase and home use. In some cases, however, only a professional will do.

You may need to call an exterminator if your infestation is widespread, is causing structural damage to your home, or is threatening your health. Exterminators are also useful if you don’t have the time or know-how to deal with the problem yourself, or if you just really, really hate bugs.
