Questions & Answers

Does it trap deer flies?

Answer by ChewyJun 08, 2026
The Rescue! Big Bag Fly Trap will not work on deer flies. This trap gets rid of common nuisance, or filth flies, while the Deck and Patio Fly TrapStik targets filth, nuisance flies, and it also catches biting flies, such as horse flies, stable flies, and deer flies.

Can I use this indoors?

Answer by ChewyJul 01, 2026
Unfortunately, the Rescue! Big Bag Fly Trap is designed for outdoor use only.

Is it safe I f horse's lick or touch it

Answer by ChewyJun 13, 2026
The attractant inside Rescue! Big Bag Fly Traps is non-toxic and made of food or feed-grade ingredients. The contents do have yeast and, if ingested, can cause an upset stomach, vomiting, and possibly diarrhea. If the trap contained flies, they can carry bacteria and may add to the gastrointestinal discomfort. Ingesting the plastic parts of the traps can cause other issues, depending on the animal, what was consumed, and how much. If you are concerned or your animal is behaving strangely, please contact Rocky Mountain Poison and Drug Safety at 1-866-767-5077. This is a free hotline for Rescue! Big Bag Fly Trap customers to speak directly with a veterinarian.

Does rain affect the bag.

Answer by ChewyJul 29, 2025
Rain is unlikely to significantly affect the effectiveness of this fly trap, although heavy downpours might cause some water to enter through the top opening. The trap is designed to be placed outdoors and can withstand normal weather conditions, including rain.

Great size trap

We use these outside our horse stalls and around the barn. They hold a lot and really help with fly control

works ok

Added the fly trap as our pens are right by a pond. While pretty and beautiful wildlife to watch, the flies are insane here. The product works ok, but the stench

Works better than the "other" brand...

These are my go to for an almost fly free barn every year. Problem I had was with the shipping...it took forever. I kept getting notices that they tried to deliver

These are my go to for an almost fly free barn every year. Problem I had was with the shipping...it took forever. I kept getting notices that they tried to deliver but couldn't...I've been receiving orders from Chewy to this address for the past 5 years. Either the people working for Ontrac don't know how google maps work, or they just put the delivery off until they feel like getting around to it. If Chewy continues to use Ontrac, I won't be using Chewy any longer.

Can’t take the smell.

This worked very well but the bait stunk so bad I had to throw it away before it got full.

works

this does a good job of keeping the fly population low but it smells really really bad. its worth the stink because it does reduce the flies.
