Bio Shield provided the insect spray for review purposes.

Bio Shield spray

Bio Shield spray was developed by a group of pharmacists to deal with insects. They discovered that insects develop a neurotransmitter called octopamine. The formula used in this product blocks the production of octopamine which in turn controls the nervous system and breathing of insects. This provides a quick way to disable the insects. For those of us who appreciate natural products, the active ingredients are all natural. This means it is safe for pets and children. Pepper is a natural ingredient that you would not want to make contact with your eyes. This product has similar warnings.

The Bio Shield insects spray bottle fits comfortably in my hand with the top protruding. It fits easily into a back pocket or easily into a small backpack. The top of the bottle is protected by a plastic seal wrap. This plastic wrap was tough enough that I needed something sharp to help in the removal. The top of the bottle is covered with a transparent removable cap. The spray mechanism is manually operated with the index finger. Per instructions, I shook the bottle well before making my first spray. The first push did nothing. On the fourth push, I was rewarded with a gentle spray on my arm. I felt cool, and there was an odor that reminded me of evergreen. It was not strong and soon dissipated.
I would call it a pleasant experience. I checked the nozzle after spraying and it was free of insect repellent. As I read over the insect list I noticed it did not contain bees. I know a lot of my good readers are sensitive to bee stings and they will surely ask me about this. I called customer service. I had to leave a message but my call was returned with a couple hours. I was told that they only listed the actual insects that were tested. My call was handled exceptionally well. I know there are insects in other geographical areas where there are insects not mentioned, hopefully, these insects will also be disabled.

Test plan

I will use the product in stages. I will spray on the outside of my wide brim hiking hat. Other places to be done separately with be the outsides of my shoes. This is the usual route that ticks invade me. Then I would do my hiking pants. This plan will be modified as circumstances change.

I am looking forward to using this product. I live in a swampy area in the Lowell Massachusetts area. I wish to thank and Bio Shield for the opportunity to test the insect repellent. Since this will be a 2 part report please check back in about a month for the last report.
