Why Flea Eggs Must Be Destroyed Before They Hatch

Summary: Dealing with flea eggs is a critical part of removing fleas from your home. In fact, if the eggs are not removed, you will have another flea infestation within a couple weeks! After giving your carpets a good vacuum, make sure that your flea product of choice contains IGR (Insect Growth Regulator) to stop their eggs from hatching.

Since a female flea can lay about 40 eggs per day, a few case studies have shown that for each flea you find, there are an estimated 120 eggs (or a further stage of the flea development cycle) around your home or garden. Your efforts to combat fleas will be useless if you don’t stop the flea life cycle. Before we look at the removal process, what do these eggs look like on your pets and other places in your house?

What Do Flea Eggs Look like?

While fleas don’t always come from pets, usually a flea problem starts with them so they may require an immediate inspection. Can you see fleas or their eggs? Well since they are very small, they can often be rather hard to find. These eggs are about 0.4mm in size and are completely white and sometimes slightly see-through. I personally think that they look like little grains of salt but I have heard a few people say it looks like dandruff. One of the most common mistakes is confusing flea dirt for these eggs. Always remember that this dirt is often a sign of fleas as it contains their feces. However, these are not eggs! Their eggs also don’t stick to animal fur (or any surfaces for that matter) and this allows them to fall off rather easily and land in your carpets, couches, bedding and other concealed places. Also, if your pet does have fleas, chances are that he or she will be scratching the bite marks as they are very itchy and this can also spread the eggs around.

Environmental Conditions That Speed Up Reproduction

Temperature has a direct effect on the rate in which fleas complete their reproductive cycle. Generally speaking, if you live in a hot environment, this will speed up this process, which gives you less time to put an end to all forms of flea life before the next wave arrives. The ideal temperate for fleas is about 25°C at an estimate of 70% humidity. How do fleas reproduce so quickly?

Well in these conditions, fleas will reproduce fast (provided they have a host available), their eggs will hatch after only a couple days and will take extra effort to get them under control because they thrive in warmth. However in colder regions, its noted that adult flea eggs take much longer to hatch and female fleas do not lay a large amount of eggs each day. Any temperatures that fall below 0°C usually results in the developing fleas becoming dormant but unless its below freezing, they can survive about 7 months without food. Quite a scary thought! Also, even though fleas prefer animals, remember that human fleas are rather common so don’t be too alarmed if you find one on yourself.

Treating Flea Eggs on Your Dog or Cat

While there are a number of natural and product based solutions for getting rid of fleas on dogs, remember that flea eggs also need to be removed! Female fleas will usually start laying their eggs in just a single day after coming into contact with your pet. Once the eggs have hatched into larvae, they feed on the dried remains of the adult fleas (blood and feces) and in some circumstances, also tapeworm eggs that was transferred from another pet or animal. While adult fleas cannot transmit these tapeworm eggs by feeding on the animals blood, they can be swallowed by your dog when it licks or bites itself (or during grooming, this is rather common with cat fleas). This will result in your pet contracting tapeworms, which can pose a fairly serious health risk if ignored.

The most common form of tapeworms on dogs and cats are referred to as “Dipylidium Caninum“. As previously mentioned, your pets are often responsible for bringing fleas and their eggs into your home so if you are currently dealing with a flea attack, make sure that you treat them on your animals otherwise you will be fighting a loosing battle. If you are unsure if your pet has fleas, signs of their presence can often be found in their sleeping areas, whether it be adult fleas, their poo or their eggs.

How to Get Rid of Flea Eggs in Your Home

The Bug Squad has a number of detailed removal methods for adult fleas. However, in this section, we are going to explore a few ways to kill their eggs to stop the flea life cycle from causing repeat flea infestations. Here are some things that you can use right away:

  1. Give your pet bedding (blankets, etc.) a good, hot wash. This will get rid of both the eggs and any lingering fleas.
  2. Vacuum your carpets and couches. If possible, try and use a water based model as these do an excellent job at removing the eggs. This also removes flea dirt and ensures that the larvae doesn’t wake up to find a tasty meal nearby.
  3. Use an IGR flea spray (natural ones are fine as well, just make sure it has a insect growth regulator) on your carpets and furniture. If you have a dog and it has a kennel, also treat this area. Remember that this wont actually kill fully developed fleas in your home. If you require this as well, you may also opt to use a flea fogger/bomb in your home. These are slightly more aggressive methods but they definitely work. Just make sure all the pets are out the house and you follow the instructions carefully. This step is extremely important as vacuuming doesn’t always cover all areas where eggs from fleas may be found and even if a small amount is left over, it could result in another generation of fleas.
  4. Use a flea comb to remove any eggs off your pets. Make sure this is done outside. Its also important to treat your pet for fleas otherwise the female fleas will simply lay more eggs and the problem will persist. You may also wash your animal with flea shampoo to get rid of eggs and even the adult fleas.

Another optional step is to use a steam cleaner to remove adult fleas, eggs and larva. The hot steam kills fleas instantly and these devices can usually be hired at an affordable price, if you don’t have one already. Finally, if you have a number of pets that frequently spend time inside your home, I highly recommend frequent vacuuming (every couple days) and checking your pets for fleas daily as a proactive measure to keep fleas away, especially during the warmer seasons. However, please stay away from pet flea collars as they can be deadly to your furry friends.

In conclusion, learning how to kill flea eggs is very important if you want to get your flea problem under control. While you may have some success with various flea products on your pets, another generation could be waiting to bug you (literally) after a couple weeks if you do not remove the eggs as well. Many people spend hundreds of dollars getting rid of fleas but fail to ensure that the eggs are removed. After reading this article, I hope this will never be you 🙂 Thanks for reading my article about flea eggs!

    Hello, about a month ago I found that my cat had fleas. I cleaned everything and used DE on the carpet and put revolution on my cat( I had been using essential oil from the vet). I have been combing him regularly and no more fleas. Here is my question: I didn’t know what to do with all my shoes so I just put them in a huge plastic bag and tied it up. Do you think it’s safe to untie and wear my shoes again? (I kept one pair out and put DE all over it. Haven’t been barefoot this whole time:)

    • Natasha Anderson Natasha Anderson says:

      Hi Kim! Yes it should be safe, go ahead. Well done on beating the infestation 🙂

    Hi Natasha! You have done so much helpful work on this site. Thank you!
    I have two Great Danes. We live in Washington State, it’s Winter and they can’t stay outside. I know there are now fleas in the carpet and on the dogs. I have a 10lb bag of DE food grade in my Amazon cart right now. I have Dawn in the kitchen and I have Frontline for extra large dogs in my Walmart cart. I’m getting ready to go to war…haha! No, I mean it.
    Does my plan of attack look like this: 1st, treat the carpets, furniture, etc. with the DE; next, bath the dogs with Dawn; Finally, treat the dogs with Frontline. I know I can bath the dogs in a week again with the Dawn, if their skin isn’t too dry, and I know that I can treat in 30 days with the Frontline. How often can I do the DE treatment? I want to stay on this so that I can get rid of all the things that hatch in the meantime.

    Thank you again for all your help. It’s amazing!

    • Natasha Anderson Natasha Anderson says:

      Hi Linda, your plan of attack is perfect, I love it. Only pointer is that if you apply the 30 day Frontline, don’t wash the dogs in water a week later. I recommend that you proceed, let me know how it goes 🙂

    we have tried everything on the market spent easily over $1,000 on topical products pills shampoos powder Etc. My littlest dog is a Maltese it seems that he has more fleas. I bought some borax and then read you had to keep the animals away from it for up to 48 hours we have a two-bedroom townhome this is practically impossible. I am interested in something that is effective but safe for animals. One cat is 15 years old and is diabetic I am worried about using all of these pesticides on him but bathing him only last about a day until the fleas are back. we have three different kinds I’ve noticed two different black kinds on both animals one kind of flea that is red on the cats only. I’m going to try the half cup baking soda and 1/2 cup sea salt on the carpet and brush it in can you tell me how long I need to leave it in for? is there some kind of repellent? we are going crazy with this!

    • Natasha Anderson Natasha Anderson says:

      Hi Marci! I recommend that you give your cat a bath in warm water and dawn soap. Yes I know, he might kill you lol but it kills fleas instantly so maybe give it a try (there is a guide on this website, under the “fleas” category). As for your home, I recommend Diatomaceous Earth (food grade), also have a guide on it. Check both out and let me know if you have any questions. 🙂

    I was starting to clean out my basement and was going through a box when I found what appeared to be fleas on some towels. I freaked out and took the box outside. The next day I examined them closer and they were definitely dead. I thought maybe I was seeing things and they had been dead all along. The next day I went to continue cleaning the boxes and found little bugs crawling on a pillow in another box. There was one that looked like an adult flea but there were little white ish bugs crawling on it also. Would these be young fleas? I’ve never noticed them on my dog and cat (both treated and looked at by the vet for fleas) but should I be worried I have a flea infestation?

    • Natasha Anderson Natasha Anderson says:

      Hi Katie! No, I don’t think that those were young fleas, perhaps something else. I personally think that you won’t get a flea infestation, just keep an eye on it though and perhaps set a few DIY flea traps (article on this blog), they are super cheap and easy to make.

  5. Avatar Jaime says:

    Hi. It’s still not clear to me whether or not flea eggs can hatch and live off an animal ie in carpet. Can you please clarify? If my house and cat are completely rid of fleas, but there are some flea eggs that survived, are they harmless or can they somehow hatch AND find my cat and re-infest? I just feel confused about the flea egg info. Thank you!

    • Natasha Anderson Natasha Anderson says:

      Hi Jaime! That is a great question, and as luck would have it, I literally just posted an article that covers flea larvae, which answers your question nicely (even shows some pics). If you go to the homepage, you will see it on the top left, check it out and let me know if you have any questions.

    Hi & thank you!
    A friend is giving me her iroomba after she replaced it post her flea attack. How should I make sure it’s free of any flea problem before I put it in my car or home?
    Thank you again!

    • Natasha Anderson Natasha Anderson says:

      Hi Diana! I recommend just emptying the collection unit and doing a physical inspection, that should be all you need to make sure it is flea free. You can also wipe it down with a wet cloth and soap, as the soapy mixture will kill fleas on contact.

    Hello I was hoping you might have some advice. Almost a week ago we bombed my house. Since than we have shampooed the carpet, vacuumed almost every day. I’ve washed pretty much everything that can be washed – more than once – we’ve steamed furniture and other items, we’ve steamed the hardwood floors I believe three times and yet every morning we get up and kill more fleas. I know I’m not the only busy person in the world, but one factor that has made all of this really difficult is I am 10 weeks away from having my fourth child. The bombs we used did have an IGR, but what I’m starting to wonder is if fleas in the pupa stage have now hatched and that’s what we’re dealing with. And if that’s the case – does the IGR effect them? Or is this like having a whole new reinfestation? Any advice would be greatly appreciated! This is really taking a toll on my body and my mind. Thank you

    • Natasha Anderson Natasha Anderson says:

      Hi Tasha! Congrats on your baby, I am also almost due again (8 weeks). I recommend that you give food grade DE a try (article on this blog). In addition, make a few DIY flea traps and leave them out, I have an article on this blog for that as well. Additionally, I am going to send you my ebook on flea removal (usually $9), just because I know that you need the help being pregnant and all. Have a good one!

    You can also salt your floors and carpets. This will dehydrate the exoskeleton and kill the fleas. I used 1-1½ boxes per room at my house. You must leave it down for minimum of 2 days. Once you vacuum it up be sure to remove the bag and discard. If you have bagless type empty the contents and discard. After emptying my vacuum into a plastic bag I tied it up and sprayed the outside with flea spray. I also sprayed the inside of my vacuums.

      Hi Patty! Thank for the great tips, really appreciate your contribution to the community 🙂

    How do flea eggs feel, can they be squished?

    • Natasha Anderson Natasha Anderson says:

      Hi Anny! Yes they can, but it is not an ideal way to get rid of them, much like trying to crush hundreds of little salt grains hehe. Hope that helps.
