Chemical Free
[This review was collected as part of a promotion.] STEM Indoor Bug Blocking Mist is a great plant based option that deters ants and roaches. Stem uses natural plant and botentical oils like gerenoil and lemongrass which attacks the insects nervous system. I love how this product is free of harsh chemicals, dyes and fragrences making it safe for children and pets to be around. The only con is that you must spray the product directly onto the insect to effectivly kill them.

So far it’s been good
[This review was collected as part of a promotion.] This definitely comes in handy for when I’m outside with my spouse or what I do is the night before I spray it outside that’s way later on in the evening we don’t have to worry about any bug. I will be getting a different to try as well.

Awesome job
[This review was collected as part of a promotion.] Absolutely a bug stopper! I wasn’t sure what type of photo to show, the bottle or where I sprayed . I used it indoors all along all door ways thru the house! No smell and it lasts

Nice!
[This review was collected as part of a promotion.] I used this in and around my kitchen counters. I no longer see any ants! It dries rather quickly. I recommend this product to use indoors. It does not smell at all.

Love the spray bottle application
[This review was collected as part of a promotion.] Texture is liquid, effectiveness is okay, it does not work the best, application is easy to use, instructions are easy to read, packaging is okay. Overall it’s a 10/10

A very nice bug blocking product.
[This review was collected as part of a promotion.] I like the sleek packaging of this product and the smaller bottle size. It’s nice and handheld. It makes storage very easy and out of reach for children. As far as effectiveness I do seem to see a decrease in bugs from spraying in my doorway. It has a light scent and I have yet to see any residue it has left. I would definitely purchase again!

It works okay, but not as well as flying insect sp
[This review was collected as part of a promotion.] I didn't really know what to expect from this product. And it worked.Okay, but not as well as I would have hoped. I live on the 2nd floor and have a lot of trees near me. And that causes us to be subject to lots of little small, gnats and fruit flies and mosquitoes

No smell
[This review was collected as part of a promotion.] I have an exterminator spraymy home due to spiders so couldn’t really be fair in judging how well this product worked. However I can say there was absolutely no harsh smell which I absolutely loved. 🥰

Great indoor bug defense spray
[This review was collected as part of a promotion.] I received STEM indoor bug blocking mist from Influenster in exchange for my honest review. Product comes in a full 10 ounce spray bottle. Has an off and on square toggle, so you can't accidentally spray the product without being in the on position. The product does have a chemical smell, but it's not overwhelming, and it does a great job of keeping insects out of my townhouse. Spraying every few weeks has greatly diminished insects from coming through the wall from other units into mine. The main ingredient is cedarwood oil, and this spray is safe around humans and pets. This product can be used on most any surface, wood frames, baseboards, under appliances. Best of all there's no wipe up required.

Safe for the family
[This review was collected as part of a promotion.] We live in the country so every big you can think of likes to sneak in, we don't like to use a lot of sprays fur to the smells of poison or being unsafe. With this Stem indoor bug blocking mist it is safe for the family and even ypur pets. It smells like cedarwood and leaves a nice scent behind. It works great in window sills, doors, cabinets and anywhere you can think of. We have been using this for about a month and it has worked great for our family.

Spray spray
[This review was collected as part of a promotion.] It is prime bug season here and I am grateful for a product that actually works in keeping them outside. Easy to use. I spray it when we will be out of the house for a little while so it has time to dry and work its magic. Only needing to use it every couple of weeks makes it a simple addition to my house chores. Will repurchase.

Scentless bug protection.
[This review was collected as part of a promotion.] The block mist appeared to work effectively in keeping the sneaky insects that try and come in at bay. Give a few inches when spraying to prevent getting the area too wet. I did not smell the product, which is great. Quick drying and stores under my kitchen sink

Spray away
[This review was collected as part of a promotion.] I’ve only just started using this because I absolutely terrified of unwanted intruders in my home. I use it along my front porch and balcony. It sprays easily and heavily. The smell is definitely on the “earthy” essential oil side instead of chemical smelling which I appreciate having two dogs. Let’s hope it does its job and keep things out!

Seems to do the job well!
[This review was collected as part of a promotion.] Every time our lawn service sprays for bugs outside, they all try to come inside. I sprayed this along the groves of my patio door and I did not get a single live bug inside! There were a lot of dead ones right outside the door. Looks like this works.

Doesn't work
[This review was collected as part of a promotion.] It does smell nice but doesn't really do anything. I didn't see a difference so unfortunately this product did not work for me. Maybe if you lived in an apartment or a smaller space you would have better results.

No smell !! Really works !!
[This review was collected as part of a promotion.] This is an awesome bug repellent. I absolutely love that it’s safe for people and pets. There wasn’t a smell after spraying it. The spray on the bottle is adjustable to your desire. I feel it works longer than 14 days.

Safe for pets and people!!
[This review was collected as part of a promotion.] This product came safely packaged in a plastic bag in case of leakage, which I loved. The best part is that it's safe around pets and humans. It sprays out a wide mist and covers the area very well. I sprayed around my doors and windows. I've not seen any unwanted pests, so it seems to work.
