So you have some bites on your body. It's a surprise you weren't expecting them. You do some googling. Your bites might even be in a line and  you don’t have a cat or a dog. Google says that's Bed Bugs.  You look and find nothing . Google says Bed Bugs hide. The  more you look  the more you become convinced it's Bed Bugs. Google is convincing you it's Bed Bugs. Google has lots of horror stories on Bed Bugs......







Let’s take a step back and have a look at the facts.

Can bites alone diagnose Bed bugs? Unfortunately, Google has this one wrong. Bites cannot tell you what is biting you. This is from Dr Richard Cooper PhD from Rutgers University, and considered to be the USA’s top scientist on Bed Bugs. In terms of research on Bed Bugs Dr Cooper is a world leader.

So back to these bites,  supposedly from an unseen insect. What is causing these bites?  They are called unexplained bites. They can be from a pest insect, BUT can also be from non pest control issues too.

Which biting pest?

You need to find what is biting you and either describe it or catch it.

When you see a bug that you think is biting you, don’t squash it, but take a good look at it and ask yourself these questions,

  • How does it move? Does it Jump,  Crawl or Fly?
  • Shape and size? Oval and the size of a pumpkin seed? Or Thin and the size of a sesame seed?
  • Colour? Reddish brown or Dark Brown or Black?


Consider investing in a trap to catch your Bed Bugs.  SenSci has an excellent Bed Bug trap, the Pyramid . SenSci also have a lure, called the ActiveCR  available. These mimic the presence of a human and  entice bed Bugs into the trap.  When do you need a a trap with a lure? SenSci advises you only need the lure then there are no humans around e.g. corridors in apartment blocks. For common areas e.g. around your bed,  you don't need the lure.

ACES pest control has these available now, for prices please click here.

If you can catch the biting insect  put it in a jar. Even though it is tempting to, please don’t squash it. Please take a clear photos and send it to us. We need to confirm its a Bed Bug.

A: Nope, you have unexplained bites. These that can be from other biting pest insects and NON pest control issues/causes.

FAQS on unexplained bites

These present as bites from pest insects/ spiders but there is no evidence of any insect or spider.

These can range from medical issues e.g. scabies/anxiety/drug reactions  to some food allergies that can present as bites or welts.

These are issues that pest control services cannot help with


If you still don’t have any evidence of what is biting you, you may choose to ask a pest controller to complete an inspection. If bed bugs are there, they should be able to find them quickly. Before engaging their extermination services, why not ask for some evidence ( from the inspection) of  Bed Bugs? No evidence,  then it may not be Bed Bugs.

Caveat Emptor (Buyer beware).

Since 2009 ACES pest control customers with bed bugs, have had no issues seeing or finding bed bugs. When I ask for photo (s) , with minutes I have them by e mail or MMS. A Bed Bug infestation is OVERT and easy to find.  This is the reason ACES pest control doesn't offer diagnostic inspections for Bed Bugs, as if you can't find the bed bugs, its most likely you have unexplained bites, NOT Bed Bugs.

If there is still no evidence of biting pests then you are right back to unexplained bites.

  1. […] Bed bugs, once thought to have been eradicated post-World War II, are on the increase and seemingly have an unstoppable march out of the bedrooms and into places we haven’t seen them before, such as offices, public transport, and more. Certainly, this was what was reported around the recent Rugby World Cup in France in 2023. Famous for feeding on human blood and the ability to hide, leaving people in fear of these unseen blood-sucking villains. But should we be worried? And what can you do about their relentless march into places away from the bedroom? Well, let’s take a step back and have a look at the basics, and then we can understand that there isn’t too much to worry about. […]
