"Great! Roofers came early, stripped entire roof, replaced the plywood that needed replacing, installed the new shingles and cleaned up the premises all in one day. We could not have been more pleased with Britt and his crew. We will definitely hire him for future improvements again."

"It went WELL! These guys are huge helps! They arrive faster than promised, they charge what they promise. There are no surprise charges like with a dumpster! I am now using a BullBag in CT and one in RI. I, alone, can keep this company busy!!!! They are awesome to work with! I HIGHLY RECOMMEND THEM! One of their managers, Vicki, was so nice, pleasant and patient with me. I was frazzled with all of the damage my property received from the hurricane. She was great!"

Nest Installation FAQs, answered by experts

Some species of bees (not to mention hornets) are aggressive and dangerous to have in your walls. If they swarm in anger or defense, they could badly hurt people in your home. Other species of bees are largely harmless and many people live in close proximity to them.

Either way, bees making hives in your walls usually causes damage. It can contribute to moisture problems, and attract other pests. Those problems get even worse if honeycombs build up. So we strongly suggest you find a way to keep bees from taking up permanent residence.

Yes, it’s actually common to see more cockroaches after you spray. It might seem like things are getting worse, but that’s usually a sign the treatment is working. Roach sprays and baits can flush them out of their hiding spots as they try to escape the chemicals. You might notice them acting strangely—slower, twitching, or out during the day when they’re usually hiding.

While many pests like rats, mice, ants, cockroaches, silverfish, and bed bugs can damage your home, termites are among the most destructive. By sheer dollar amount, the damage from a bad termite infestation is unparalleled, as they can ruin walls, floors, roofs, and wooden support materials, potentially requiring massive reconstruction. Other highly destructive pests include rodents, carpenter ants, and bees that build hives within walls. If you spot signs of termites or other pests, you should hire an exterminator immediately.

Cleaning your home after discovering fleas is an all-day job, but this may not be the last you see of them. Some fleas are resistant to initial treatments and may lay eggs that will hatch after your first pass. Continue with treatments for one to two months to fully eradicate them.

The hardest ant to get rid of is the pharaoh ant. Although small, pharaoh ants can spread infections in hospitals and are known to transmit infectious diseases in schools, apartment complexes, and office buildings. For this reason, they’re best handled by pest control professionals.
