To get results faster, you have to be aware of how severe the problem is before you actually start applying any substance. If you live in a big house or if the bugs have managed to spread rapidly and you are overwhelmed by their presence, you might need the Harris toughest bed bug killer.

Frequently Asked Questions


 Q: Does Harris bed bug killer kill eggs?

Bed bugs can spread very rapidly, and they do this by laying eggs. The female bed bugs typically lay their eggs on a hard surface such as the bed frame, for example. Other surfaces where they typically lay eggs include cracks, upholstery, and clothes. Just one female can lay as many as 250 eggs. 

Also, the eggs hatch in only 7-14 days, becoming nymphs that will need only two-three more weeks to become adults. Moreover, even nymphs suck blood to feed themselves. 

Once these eggs hatch, the infestation problem reoccurs although you might have thought you’ve gotten rid of bed bugs initially. For this reason, it is essential to use products that don’t only kill adult bugs, but also their eggs.

Even a cheap Harris bed bug killer will also kill the eggs and not only the mature specimens. This is what partially makes these products so popular and accounts for their efficiency. 

Q: How long does it take for Harris bed bug killer to work?

Bed bugs can hide in the smallest cracks and lay their numerous eggs there. This is why it is sometimes difficult to exterminate them by applying specialized products once only.

Even the most affordable Harris bed bug killers guarantee efficacy in fighting against bed bugs, but to achieve good results, you have to apply the product according to the instructions and according to the level of infestation. If the problem is not critical, you may be able to tackle it by using limited amounts of product.

However, if you are in desperate need of a quick solution, you might want to consider the Harris 5 minute bed bug killer products that are some of the fastest solutions provided by the company. These products kill bed bugs within only 5 minutes after the first contact. 

If you are looking for non-toxic options, the Harris diatomaceous earth bed bug killer can be of great help. However, products based on diatomaceous earth usually need more time to work because they are based on physical action, meaning that the bugs need to touch it. 


Q:  How do you know if bed bugs are gone?

After you finish reading these Harris bed bug reviews, you’ll definitely be more prepared to fight bed bugs and you might even proceed directly to buying one of the solutions presented above. In this case, there might be one more important question we have to answer before we part ways – how do you know when the bed bugs are gone?

Sometimes these annoying creatures suddenly reappear just when you were finally feeling comfortable in your home again. To be 100% honest, we have to say that there is no certain way to know for sure when all of the bugs are gone. You just have to be patient, wait, and see. 

These tiny creatures can linger in the narrowest places, which makes it difficult to ascertain that there are no more bed bugs eggs in the house. Generally, you should wait for at least 2 weeks after the final application and if no bugs start showing up again, the treatment was most probably successful.
