I can't say for sure a mouse couldn't get in, but it would have to do some major chewing work to do so. We got this to sort a wasp problem and it worked a treat. **Q: Does this vent come with screw fixings?** A: No fixings were supplied with mine. Just a tip to remove the outer grille you need to use a flat knife push down on one of the edges and lever it off.when fixing the back plate don't over tighten screws or the grille will be hard to press on. **Q: Can I buy a plastic ducting connector that will fit into the 150mm grill?** A: Yes, buy plastic zip ties and use one of them **Q: What is the size of the 'clicked in place' removable grille, and could this part be supplied seperately.** A: The grille is the size of the square vent and you will have to ask the supplier if the sell it separately. ## Frequently Bought Together - Kair White Louvred Wall Vent Grille 155mm External Dimension with Flyscreen and Round 100mm - 4 inch Rear Spigot - Manrose Insulated Ducting 10m x 4" - VENTS UK 100 mm / 4'' White PVC Round Ceiling Ventilation Cover/Plastic Air Vent Diffuser with Fixing Ring for Bathroom Kitchen Hydroponics in-Line Extract Fan Air Conditioning HVAC --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/50324843-white-100mm-louvred-wall-vent-grille-with-flyscreen-and-rear](https://www.desertcart.us/products/50324843-white-100mm-louvred-wall-vent-grille-with-flyscreen-and-rear) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-04*
