What Research Does Know
Every insecticide is poisonous to some extent, with research suggesting that when given in higher doses of exposure, it can possibly be a contributing factor towards miscarriages, as well as preterm deliveries or even birth defects.
There are certain chemicals in insecticides such as PCB (polychlorinated biphenyls) that are known to have a weak, estrogen-type hormone of mimicking-qualities — known as endocrine disrupters — and scientists feel these may be affecting the reproductive system in unborn children.
Researchers know that all of the chemicals have the potential to harm, including the all-natural brands. They have to have ingredients that are going to kill an infestation of bugs, so they have to be harmful to an extent. They strongly urge that all labels be thoroughly read and all directions followed carefully when using the products, especially if you have no option but to use them whilst pregnant.
Alternatives to Insecticide
- A less toxic approach would be to use boric acid — the blue form — sold at hardware stores. This will not be harmful to you or the baby.
- Use baits. It may take longer to rid yourself of the roach problem but it is a non-toxic approach and will eventually see your home roach free.
- Call a professional and inform them of your pregnancy. It will be expensive, but they will do all the work, whilst making sure you are safe in the process.
- Make the roaches want to leave. Remove food sources. Keep food off tables and counters. Put leftovers in sealed tight containers and keep the refrigerator and surfaces scrubbed down. Seal all the cracks and openings in your home that roaches could possibly use as a way in and out. This takes close inspection, because they can squeeze through the smallest of spaces. Keep trash outside in a tightly sealed garbage can/refuse box.

Why Spray for Roaches
Not spraying for roaches is unhealthier for you and the baby than spraying for roaches. They carry diseases, not through bites or stings but by what is on them. They’re filthy with excrement and vomit and can cause illness by way of direct contact. If they scurry over your surfaces, or on top of your dishes or utensils without your knowledge, and you use those things, you’re being exposed to whatever disease is living in their poop.
They carry any number of nasty, horrible infections along with a multitude of different bacteria, as well as cause allergies to flare and asthma to act up. In pregnant women they can cause respiratory issues. So, having an infestation when pregnant could be dangerous for your breathing, and thus your child.
Those are reasons enough to want to spray these suckers, but here are some more: They will crawl on you at night and expose you to all of the creepy crawly diseases they’ve picked up as they scurry through trash, poop and worse.
Professional Services
- When you call, let the service provider know up front that you are pregnant. This is so when they come to get rid of the infestation they’ll take the necessary steps to be especially careful when applying any chemicals.
- The professional will let you know how long you will need to stay out of your home until the pesticide has completely dissipated.
- Prior to them coming, remove all of your food, dishes, and utensils from your home.
- When the spraying is finished, have someone else come in and wash the areas thoroughly where you will be preparing food.
- When you get back home, open all windows possible in order to air the entire house.
- When you find any dead cockroaches, just sweep them up and toss them out. Don’t do a thorough cleaning or vacuuming of the house for about a week after the extermination, or you will undo what the professional has done for you. You don’t want to clean away the treatment.
Is Fly Spray Harmful When Pregnant?
OLE or PMD are not recommended.
Research shows no adverse effects on baby survival or growth or development at birth or as of the age of one after being exposed to any kind of insect repellent during the second and third trimesters. Authorities indicate that it should be used minimally and in conjunction with other measures such as covering up with long sleeves, long pants, socks, covered shoes, and an overall cautious approach.
Insect borne diseases are far worse to deal with than any insect repellent. Flies, mosquitoes, and other insects carry dangerous, even life threatening diseases and repelling them is far better than being exposed to what they can infect you with.

What Helps Bug Bites When Pregnant
- You can apply ice to the affected area which will reduce the swelling caused by the bite.
- You can also apply aloe vera. This is another way to reduce the swelling. You have to be careful with this, though. It does have the potential to bring about an allergic reaction if left on the skin for too long.
- Avoid scratching the area, put a Band-Aid/plaster over it. It will clear up on its own within a day or two time.
Do Pregnant Women Get More Bug Bites
- Wear clothing that is lighter in colour. Mosquitoes, especially, prefer folks who are wearing darker clothing such as blue and black.
- You need to wear long sleeves and no shorts. This way you’ll limit the access they have to your skin.
- Wear clothing that is loose fitting. Mosquitoes can actually bite you through clothing that is tight fitting. If you are wearing tight fit clothes, make sure that the weave is also tight.
- Of course, as we mentioned, use a repellent that has been tested and registered. There will be a registration number above the ingredients on the label. DEET, Picaridin and IR3535 are the top three-rated products to be used by women that are the safest and should be used to repel bugs.
- Being outside you may want to use a Citronella candle or maybe some tiki torches or even some campfire smoke if you may be camping. These things are natural ways to repel bugs that are in no way harmful to a pregnant woman.
