How do I safely use the bed bug Bomb?

Simple! You will need to set the bed bug aerosol at a proper point within the bed bugs infested room and activate the canister. Ensure that all the doors and windows are closed for at least 2 to 3 hours during the application time.

Improving air circulation in your room using a fan or air conditioner helps the bed bug bomb penetrate effectively into crevices/cracks beneath beds and furniture.

Bed bugs bombs contain flammable chemicals that can affect both your humans and pets. However, you must properly identify the bugs – check the pictures of bed bugs.

Therefore, the following precautions should be followed during use:

1. Read keenly and follow directions given in each aerosol canister during application. You will need to note main things like cautions/warnings, application procedures, and side effects.

2. Cover all food substances in your room and gaming toys for children and pets airtight. Children may put fumigated toys in their mouths. Food absorbs this chemical leading to food poisoning.

3. Get the accurate area/volume of room you want to treat with bed bug bombs. To do this, measure the length, width, and height using a foot or tape measure.

Then, multiply the measurements of these sides to get volume. Do the same for other rooms and sum the volumes of each room. Compare the total with the indicated volume in the aerosol canister.

4. Switch off lights/deactivate sockets from mains and remove anything that can spark. Bed bud bombs are highly flammable due to aerosol propellants used. Ensure that you place your aerosol can/canister at least 7 feet from any spark source within your house/office.

5. Vacate your humans and pets from the room being treated. When inhaled, beg bug bombs cause air track discomfort. Bed bug bombs can kill pets such as dogs. Keep off the house for two to three houses.

6. Use the right number of bed bug bombs in a given area/space. Excess Bed bud bombs are dangerous as it may take long before it leaves your room.

Also, some residuals may be difficult to get rid of. Less quantity of bed bug bombs will cause inefficient killing of these bloodsuckers. You will therefore need to stick to application instructions – if you are unable to engage an examiner.

7. Inform your neighbors about bed bug bomb application – this will minimize any effects that may cause chaos on the eve of application. Recommend them to switch off any spark source during that time.

8. Keep off people from accessing the room. Ventilate the office/room/s well before entering. Ensure you open doors and windows to let in fresh air for 60 minutes.

9. Store the unused bed bug bombs in an enclosed place away from children and pets.

Why Bed Bug Bombs won’t kill all your bed bugs.

Unfortunately, most bed bug bomb users cannot complete all bed bugs in their place. This is one of the many challenges in household pest control.

However, several reasons may lead to the incomplete killing of bed bugs in your room/office/house or warehouse while using a bed bugs bomb. These include:

1. Incomplete Penetration. Bed bug bombs work by spraying the gaseous insecticide killer over bed bugs and their egg, thus killing them.

Any bed bug or eggs that are not reached is not killed. The insecticide is expected to access the cracks/crevices, mattress seams, and roofs, sealing those points, thus killing bed bugs by suffocation.

2. Incomplete air circulation in your room limits the bed bug bobs’ action from penetrating some bed bugs’ hideouts such as crevices/cracks, ceiling, inside the mattress, bedding, clothes, or under the carpets.

You will need to turn some of your items like chairs, couches, beds, clothes, picture frames, and drawers to enable killing gas to properly penetrate these sections.

3. Less quantity application. All bed bug bombs have application descriptions, which also indicated volume capacity, mode, and area that each aerosol canister could serve. Administration of larger space won’t kill all bed bugs.

4. Mutation/chemical resistance. Most bed bug bombs contain pyrethrin or pyrethroid. EPA banned the use of DDT in 1972 – this led to the development of synthetic pyrethroids, which were then used to kill bed bugs.

According to Economic ecological research, report shows that most bed bugs are becoming immune to these chemicals. They undergo mutation, and there these chemicals may not kill them.

By 2010, some bed bugs species had gained complete resistance/mutated and could not be killed by these chemicals. In case you find yourself in such a case, ensure your use of an alternative method such as heat treatment.

5. Using the wrong bed bug bomb. There are varieties of bug bombs in the market. Purchasing the wrong bug brand won’t kill bed bugs. You will need to be keen on the labels indicating the kind of insects killed by a given fogger.

6. Less powerful bed bug bomb. The market is currently flooded with varieties of bed bug bombs. Check diatomaceous earth for bed bugs.

Though they can kill bed bugs, these aerosol foggers do not have enough concentration to kill bed bugs. You will need to test various bed bug bombs or get insight through the reviews from other users in the universe.

Which alternative bed bug killers will work?

Bed bug bombs may fail to kill bed bugs in your house/office effectively due to some of the reasons I have highlighted above. Below are some of the alternatives that you can use instead.

1. Heat treatment. This involves heating the bedbug-infested room to a temperature of 125 degrees Fahrenheit.

At this temperature, all bed bugs and their egg will be dead. Check the bed bug steamer.

This will take a longer time and cost as compared to bed bug bombs. This calls you to vacuum clean all your bed bugs-infested items and house.

The vacuum machine sucks both the adult and their eggs. However, this method may not remove some of the bed bugs hidden deep in mattresses and crevices.

2. Dry cleaning/using a dryer. This requires you to put your bed bug-infested clothes or bedding into a dryer operation at a temperature of 125 degrees Fahrenheit. Here’s how a dryer kills bed bugs.

This temperature will kill all the bed bugs and their eggs. This method may not kill bed bugs in some items like couches, mattresses, or beds since these items can’t fit in your dryer. The dryer is unsuitable for entire room treatment.

3. Using bed bug sprays. Spray bedbug-infested room or items directly using bed bug spray available in the market.

This method is dangerous as you are directly involved in spraying, and thus you may get affected by these aerosols, which cause nausea, dizziness, breathing discomfort, and stomach upset.

4. Dispose of all bed bugs, infested items. This is not easy since you may not be willing to dispose of your newly bought items.

But, it is recommendable to dispose of old bed bugs infested items or burn them. NB: Desist from purchasing any second-hand items – they are one means of transferring bed bugs into your home/office.

5. Setting bed bug traps. These will trap bed bugs that crawl into them. They are not very efficient as they may not trap bed bugs that do not come from other hideouts and their eggs.

Ways That Will Make Bed Bug Bombs Kill Bed Bugs Efficiently

Though bed bug bomb may not completely kill bed bugs in your bed bugs infested office, home, or warehouse, you can improve its action/performance by doing some of the following things:

1. Ensuring your room/house/office doors and windows are airtight closed during the 2 to 3 hour application time will concentrate the killing gas within all possible bed bugs hideouts in the room.

2. Turning all bed bugs-infested items in your room. Ensure you spread bed bugs infested clothes, bedding, chairs, couches, or footwear and turn the beds and wall units in your room to offer ample penetration of bed bug bombs into those places without obstructions.

3. Using several small quantity bed bug bombs. Place several bed bugs aerosol canisters at various points in your room. This helps in quick access and penetration of active insecticide simultaneously in the room.

It also prevents bed bugs from hiding in one part of the room when they sense danger. NB: The total of all these canisters should not be more than the room’s volume being served.

4. Boosting air circulation. Insufficient air circulation within the bed bugs infested room cause incomplete penetration of the bed bug killing gas to such place as beneath the bed, shelves/drawers, under the table, couches or carpets.

You can boost room air circulation using a fan or air conditioner. Remember to power these devices from outside to prevent any spark.
