Specs
B3X Exclusion Strips are an exciting and innovative exclusion product for birds, bats, insects, and more! Place stips behind shutters, in ridge vents, fill gaps along roof lines, or seal off attic vents. The "compression anchor technology" constructed of reticulated polyurethane material allows installation without adhesives or tools. Each box contains 32 two-foot strips, for a total of 64 linear feet.
Professionals agree that there are never too many options when doing wildlife exclusion work. Whether it's a gap along the roof line or soffit, space between siding, cracks behind shutters, or crevices along attic or ridge vents, stuff B3X Exclusion Strips into these openings to keep those nuisance pests out!

This stuff is extremely easy to install. Can easily be trimmed to any size you need. Its my go-to for bat exclusion work.

I have a 124 year old house with shudders and the bats were spending the daytimes behind them making a horrible mess. B3X is working like a champ keeping them out. My only wish is that you would sell a half size box. I had enough for all but one window and really don’t want to buy another full box as it is expensive!

I have used these on multiple stone homes with sparrows behind the shutter. They are easy to install, but you do need to take your time and fill the voids properly. I have installed this on two homes in the same neighborhood with heavy bird pressure and the sparrows will pick at this product and pull chunks out of it until they can re-enter the space. I now use Methyl Anthranilate aroma and/or apply a gel on the outer edge of the strips (unless highly noticeable). The combo of products seem to be working better.

Great product. Problem solved. Highly recommended for stone attached shutters.

I was having a lot of trouble with birds building nests behind my shutters. No matter what I did it did not discourage them from picking and removing whatever I put behind the shutters . This product works and so far they haven't been able to pull out. Highly recommend.

I used this product extensively for the past several weeks for bat exclusion. Far less spray foam required and still allows air flow for attic vent slots to circulate. Excellent product!

This stuff is foam gold. I have the thin, plastic, hollowed out shutters on the front windows of my stone house. Perfect 1-2in spaces for sparrows to nest. This stuff was cut to the perfect size for my shutters and was easy to trim with regular scissors where modification was necessary. Quick and easy to install. Shipping was fast too! Yeah, it’s expensive for foam. But this was the ONLY simple solution I could find on the entire internet after quite a bit of searching. My problem is solved. I love it when a plan comes together!

Purchased this product after it was recommended to me by a friend. It works great for odd areas when doing bat exclusions. Great product, ordering more this week.

Just found this product. The first box I worked with did AWSOME a spot that I would normally foam and then wait to see how big it was going to get so I could trim it back, no need The B3X will cover that. No clean up, no mess. Behind shutters, in ridge caps on tin roofs. Just a couple of areas. I own a Nuisance Wildlife Control company and now that I have found the B3X, my company will be using a lot less foam.
